Thu, 18 Mar 2010 15:06:52 +0100 Reverse shoulder arthroplasty as a salvage procedure for failed conventional shoulder replacement due to cuff failure—midterm results http://www.medworm.com/index.php?rid=3368380&cid=s_33389_31_f&fid=33389&url=http%3A%2F%2Fwww.springerlink.com%2Fcontent%2Fw774261057063k77%2F Abstract  Our goal was to evaluate the objective and subjective midterm outcome after revision of a failed shoulder arthroplasty with a reverse design prosthesis. Twenty consecutive patients with 21 revisions of a primary shoulder arthroplasty using reverse shoulder prosthesis Delta III® were followed up postoperatively for a mean of 46 months including clinical and radiological examination. Complications were recorded and Constant score, DASH and SF36 were assessed. With the numbers given a significant reduction of pain was achieved from 8.7 to 3.0 (p < 0.001). There was a significant improvement of active flexion from 43° to 97° (p < 0.001) and active abduction from 44° to 90° (p < 0.001). However, at the same time, active external rotation wi...

All patients were fitted with cementless prostheses in 2008. For the THA patients with dysplastic hips, we attempted to restore their hip centres to the position of the true acetabulum. Digital templating was the method chosen to achieve hip centre restoration. The prosthesis prediction accuracy (within ± one size using digital templating) was 20 (48.8%) for the cup size and 30 (73.2%) for the stem size. Meanwhile, for patients with other primary diseases, the accuracy for the cup size within ± one size was 34 (70.8%) and for the stem size accuracy was within ± one size in 38 (79.2%). Between the two patient groups, there was a sig...

In each group, a transverse fracture was created at a point 70% distal between the lesser trochanter and the adductor tubercle. One femur out of each matched pair was then stabilised with an interlocking intramedullary nail (nail only group) and the other femur was stabilised with plate augmentation after interlocking intramedullary nailing (plate augmentation group). The bending load to promote 5-mm displacement showed statistically significant differences between the plate augmentation group (mean 843.36 ± 409.13 N) and the nail only group (mean 315.02 ± 219.80 N) (p = 0.001). Torsional torque at the angle of 15 degrees showed statistically significant differences betw...

Adult patients treated for hip fracture between the years 1997–2007 were included in the study. Retrospective statistical assessment of continually gathered data focussed on epidemiology and demographics. The study involved 3,683 patients (2,678 women and 1,005 men). Patients older than 70 years accounted for 82% of all cases. There were 2.7 times more women; in patients younger than 60 years men significantly outnumbered women (p < 0.001). The mean patient age was 77.9 years (SD ± 12.6; women, 80.3 years; men, 71.5 years). There was a slight increase in the average age in both sexes. Trochanteric fractures accounted for 54.7% and femoral neck fractures ...

The histological results showed that the hierarchical structure of the mutant cartilage and the embedded chondrocytes were markedly abnormal. The expression and distribution of type II collagen was non-uniform in sections of the mutant cartilage. Ultrastructural examination showed obvious abnormal chondrocytes and disarrangement of collagen fibres in the mutant cartilage. Furthermore, the predicted stability of type II collagen dramatically decreased with the substitution of serine for glycine. Our study demonstrated that the p.Gly1170Ser mutation of COL2A1 caused significant structural alterations in art...

In contrast to conventional total hip replacements, only a few clinical hip resurfacing trials using radiostereometry (RSA) have been reported, and solely for the Birmingham hip resurfacing arthroplasty. The purpose of this RSA trial was to describe the migration pattern of a new hip resurfacing system (ReCap) within the first two years after primary surgery. Twenty-six patients underwent total hip replacement. The patients were followed-up for up to 24 months and were evaluated with the use of radiostereometric measurements. The prosthesis showed mean translations and rotation close to zero....

The subtleties in biomechanics of the wrist joint and their role in the production of the symptoms are presented as five cases from a retrospective study. The relationship of the symptoms to the patients’ job activities is also discussed. The embryological and anatomical studies show that the tip of the ulnar styloid is covered by the TFCC. Therefore, the term “ulnar styloid impingement syndrome” is adopted for the entity in cases in which the TFCC has remained intact.

This is partly due to polyethylene wear of the articular surface induced by excessive articular contact stress during elbow motion. The aim of this study was to dynamically evaluate in vivo three-dimensional elbow motion after total elbow arthroplasty. Twelve patients (15 elbows) who underwent operation with the Osaka University Model Total Elbow System were analysed using X-ray fluoroscopic imaging and a two-dimensional/three-dimensional registration technique, which could accurately estimate the three-dimensional spatial position of components. Valgus/varus angle and rotation between humeral and ulnar components showed wid...

Report of 7 patients http://www.medworm.com/index.php?rid=3304584&cid=s_33389_31_f&fid=33389&url=http%3A%2F%2Fwww.springerlink.com%2Fcontent%2Fl488n220u62q3714%2F Abstract  Injudicious reaming of the tibial shaft can lead to extreme local hyperthermia, which in turn can result in the rare but catastrophic complication of segmental bone and soft tissue necrosis (osteocutaneous thermal necrosis). This is a retrospective study showing osteocutaneous thermal necrosis occurring after tibial intramedullary reaming salvaged by Ilizarov reconstruction in seven patients from the collective experience of four limb reconstruction centres. All patients were males, with an average age of 51.8 years (range, 30–70 years), who had undergone intramedullary reaming during the treatment of closed tibial fractures. In all patients, circumferential bone and variable contiguous soft tissue necrosis developed a few days after reaming. Bone and ...

The acetabular shell was inserted at 0–20° of anteversion at five degree intervals. By using different head sizes (28 mm, 32 mm, 36 mm), the degrees of dislocation were recorded by computer navigation. The 36-mm group consistently showed better stability compared with the 32- and 28-mm groups, regardless of the degree of cup anteversion. Within each group of head size, the hip was significantly more stable when the cup anteversion increased from 0° to 10°. The difference became insignificant when it increased from 15° to 20°.

Total knee arthroplasty is an effective procedure to relieve pain, restore knee function, and improve quality of life for patients with end stage knee arthritis. The aim of this study was to investigate the inflammatory process in patients with primary knee osteoarthritis before surgery and in subsequent periods following total knee arthroplasty. A prospective study of 49 patients undergoing primary total knee replacements was conducted. The patients were evaluated by monitoring serum interleukin-6 (IL-6), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), knee skin temperature, and clinical status.

The use of constrained liners is an option for the management of chronic hip instability, typically used after other methods have failed. The purposes of this study were to evaluate the overall clinical outcomes and failure rates of a tripolar constrained liner design, to assess the radiographic outcomes of its use, and to examine whether various factors such as abductor mechanism quality and history of previous revision surgeries were associated with an increased risk of failure. Forty-three hips in 39 patients who had a mean follow-up of 51 months (range, 24–110 months) were reviewed. Ninety-one percent of the hips (39 of 43 hips) did not need any revisions over the study ...

Computer tomography was performed in 24 children in the mean age of 6.1 years. There were eight boys and 16 girls. Gleno-scapular angle, congruency of gleno-humeral joint and joint deformity according to Waters at all. criteria were measured. The mean functional score according to the Mallet classification system was 12.3 points. The joint was stabile in nine, subluxed in seven and dislocated in nine cases. Gleno-scapular angle in affected joints was 23.3° and in non-affected 4.5°. The glenoid was statistically more retroverted in older children. With more severe posterior incongruence there was st...

Operating times were collected and related to the number of procedures done by residents performing closed reduction and internal fixation using cannulated screws for intracapsular fractures of the hip and cephalomedullary nailing for trochanteric fractures, as well as hemiarthroplasty for displaced intracapsular fractures. The mean operating times decreased significantly for all four procedures studied, though at different rates. For cannulated screws, the mean duration of surgery decreased from 47.8 minutes to 30.1 minutes for procedures 21–25. For cephalomedullary nailing without distal locking, the mean operating time decreased from 73.3 minutes to 36.3...

Ninety Wistar rats were divided into three groups. Group A was fed with a normal diet as control; group B was fed with a normal diet and T-2 toxin; and group C was fed with a low nutrition diet and T-2 toxin. The left knee specimens were collected, fixed in formaldehyde solution, stained by hematoxylin and eosin and Masson. After two weeks, the epiphyseal plate showed necrosis of chondrocytes in groups B and C. After four weeks, more obvious chondrocyte necrosis appeared. The positive rate of Lamellar necrosis in group C was signific...

A wide range of options are currently practised, ranging from conservative measures through various types of operations and, recently, use of growth factors and emerging gene therapy techniques. The end result of these methods is usually a fibrous repair tissue (fibrocartilage), which lacks the biomechanical characteristics of hyaline cartilage that are necessary to withstand the compressive forces distributed across the knee. The fibrocartilage generally deteriorates over time, resulting in a return of the original symptoms and occasionally reported progression to osteoarthritis. Our purpose in this study was to review the aetiology, pathogenesis and t...

An orthopaedic view http://www.medworm.com/index.php?rid=3281702&cid=s_33389_31_f&fid=33389&url=http%3A%2F%2Fwww.springerlink.com%2Fcontent%2Fx421u255p5t0217g%2F Abstract  In recent years, the locked plating system has gained favour in the treatment of certain fractures in adults; however, there is not much information regarding its use in children. We think there could be some advantages and applications such as: an alternative to external fixation, the bridge plating technique, unicortical screws, removal of hardware, metadiaphyseal fractures, periarticular fractures, poor quality bone, and allograft fixation. However, there are some disadvantages to keep in mind and the final decision for using it should be based on the osteosynthesis method principle the surgeon would like to apply. In this review article we discuss the up-to-date possible clinical applications and issues of this system. Content Type Journal ArticleCategory ...

Clinical rating was based on the forefoot score of the American Orthopaedic Foot and Ankle Society (AOFAS). Weight bearing X-rays were used to perform angular measurements and assess the first metatarsophalangeal joint (MTP 1). At follow-up the mean AOFAS score had improved significantly (p < 0.001), but only 55% of the feet showed a perfect realignment of the first ray. Patients with a hallux valgus angle exceeding 30° and pre-existing degenerative changes at the MTP 1 joint displayed inferior clinical results (p < 0.05). Nearly 20% of the patients suffered from pain at the MTP 1 joint. This was clearly attributed to an onset or wo...

A mathematical model of the hip joint was generated by using a laser scan of a dried cadaveric hip. The range of motion was assessed with a cup inclination and anteversion of reference and with non-optimal cup positions. Large femoral heads increased the range of motion, compared to the 28-mm femoral head, in the presence of a hip prosthesis correctly implanted and even more so in the presence of non-optimal cup positioning. However, with respect to the 32-mm femoral head, large femoral heads showed limited benefits both in t...

The scores showed no significant differences between the two groups at both early and late follow-ups. Our results revealed that MUA for frozen shoulders is a simple and noninvasive procedure to improve symptoms and shoulder function within a short period of time. Even though DM is a predisposing factor to frozen shoulder, non-insulin dependent DM alone does not influence both the short- and long-term outcomes of frozen shoulder.

A review of literature http://www.medworm.com/index.php?rid=3278054&cid=s_33389_31_f&fid=33389&url=http%3A%2F%2Fwww.springerlink.com%2Fcontent%2Ft54063q422m83880%2F Abstract  Anterior cruciate ligament (ACL) rupture, one of the most common knee injuries in sports, results in anteroposterior laxity, which often leads to an unstable knee. Traditional ACL reconstruction is performed with autograft; disadvantages of this technique are donor site morbidity and a long rehabilitation period. In the 1980s, artificial ligaments became an attractive alternative to biological grafts. The initial enthusiasm surrounding their introduction stemmed from their lack of donor morbidity, their abundant supply and significant strength, immediate loading and reduced postoperative rehabilitation. Synthetic grafts made of different materials such as carbon fibers, polypropylene, Dacron and polyester have been utilised either as a prosthesis or as an augmenta...

The purpose of this study was to determine if surgery improved function and QOL in these patients. Furthermore, the authors assessed the patients’ and parents’ satisfaction. %FVC increased in all patients after preoperative inspiratory muscle training. Scoliosis surgery in this group of patients presented no increased risk of major complications. All-screw constructions and fusion offered the ability to correct spinal deformity in the coronal and pelvic obliquity initially, intermediate and long-term. All patients were encouraged to continue inspiratory muscle training after surgery. Th...

We propose the transfer of the latissimus dorsi muscle for treatment of irreparable ruptures associated with functional impairment and chronic pain. Five women and 11 men were so treated and reviewed with an average follow-up of 26 months. The mean age was 60 years. Four patients also had subscapularis deficiency. Results were assessed with the Constant score and the Oxford shoulder score. Humeral head position was analysed. Statistical analysis was performed by the Wilcoxon non-parametrical test. The Constant score increased by 24.2% (p = 0.001) with all parameters showing improvement. Nine patients showed improved humeral head positioning in internal rotation. Three of four patients...

From January 1998 to September 2003, 18 patients with wrist defects due to distal radius grade III giant cell tumour resection were treated with vascularised fibular graft and were followed-up. The limb function was restored to an average 80% of normal function and bone union was achieved within six months in 18 patients with vascularised fibular graft. MSTS score averaged 25.6 and ranged between 21 and 29; Mayo wrist score averaged 56 with a range from 40 to 65. It is appropriate to use the head of the fibula as a substitute for the distal radius.

These procedures are often performed under image intensifier guidance. The cost of these gadgets precludes their common use in resource poor regions. External jig-aided intramedullary interlocking nailing is relatively cheap and offers the chance for performing these procedures in resource poor regions. The aim of this study was to document the advantages, challenges and outcome of this form of treatment in a resource poor setting. The Surgical Implant Generation Network (SIGN) implants and instrumentation were used for this study. Thirty-seven limbs in 35 patients were included. There were 30 males and five females giving a ratio of 6:1. The mean age...

Regular elite competitors are known to be at risk of both acute and chronic injuries. It may be postulated that skaters at the temporary rinks are at high risk of acute injuries from falls due to both their lack of expertise and the inherent dangers of ice skating. Injuries sustained at skating rinks present a significant burden to local healthcare resources, in particular orthopaedic departments. For the first time, Cambridge hosted such a facility from November 24, 2007 through January 6, 2008. We sought to identify the most common injuries encountered and to quantify the orthopaedic burden.

Histological examination showed good subsynovial and intra-fascicular vascularity with free nerve endings in the majority. Morphologically normal mechanoreceptors (H&E) and proprioceptive fibres (positivity with monoclonal antibody for NFP) were found in 46% and 52.4% of stumps, respectively. A statistically significant correlation between injury duration and persistence of mechanoreceptors and proprioceptive fibres was noted. More fibres were seen where ACL remnant was adherent to PCL.

In this retrospective study the follow-up of 19 patients with 23 osteonecrotic femoral heads treated with implantation of an osteonecrosis intervention implant was assessed. From 19 patients with 23 necrotic femoral heads, there were 13 cases in which a total hip replacement was necessary. This implies a survival rate of 44% after implantation of an osteonecrosis intervention rod after a mean follow-up of 1.45 years. The outcome after core decompression combined with the insertion of a tantalum osteonecrosis intervention implant did not show superior results compared to core dec...

The aim of this study was to analyse the influence of the surgical approach on the direction of the dislocation in patients treated by a hemiarthroplasty (HA) or total hip arthroplasty (THA) after a femoral neck fracture. Fracture patients have a high risk for dislocations, and this issue has not been previously studied in a selected group of patients with a femoral neck fracture. We analysed the radiographs of the primary dislocation in 74 patients who had sustained a dislocation of their HA (n = 42) or THA (n = 32). In...

The precise timing of surgical intervention for secondary lesions in long bones can be difficult to determine. This paper aims to evaluate a classic scoring system. All radiographs were examined twice by three orthopaedic oncologists and scored according to the Mirels’ scoring system. The Kappa statistic was used for the purpose of statistical analysis. The results show agreement between observers (κ = 0.35–0.61) for overall scores at the two time intervals. Inter-observer agreement was also seen with subset analysis of size (κ = 0.27–0.60), site (κ = 0.77–1.0) and nature of the lesion (κ = 0.55–0.81). Simila...

Median follow-up was about 15 years for 134 females and 58 males. Among the knees, 118 had an average opening wedge for varus angle of 13° and 106 had closing wedges of 11°. Knee Society scoring before osteotomies was 68/200 for opening wedge and 81/200 for closing wedge. Modified Ahlback classification showed preoperative grades I (n = 44), II (78), III (83) and IV (19). Healing delay was 55 days for closing and 70 for opening osteotomy. Twenty-nine knees were still painful. Twenty-eight patients were revised and 19 others had complications. After opening wedge osteotomy, scoring was 101/200 and valgus angle was 2°. After closing wed...

Excessive premature loading of articular cartilage, most often the result of a knee injury, has been shown to result in increased degenerative changes and pain in the younger patient. Instability may also contribute to the degeneration of cartilage and must therefore be considered in the treatment of osteoarthritis in the young adult. High tibial osteotomy has been described as a treatment option for malalignment in the older, less active adult and has shown promising results in a younger, more active population. Osteotomies for instability are more controversial and should be considered in more complex injury patterns. Content Type Journal Arti...

However, few studies have been published about functional outcome after joint reconstructive procedures for hallux rigidus. The purpose of this study was to assess clinical, radiological and functional outcome, with special regard to recreational and sports activity, after first metatarsophalangeal joint replacement in patients affected by hallux rigidus grade III. Twenty-three patients who had undergone total joint replacement of the first metatarsophalangeal joint were examined preoperatively and three, six, 12 and 18 months postoperatively.

The main goal is to decrease the prominence of the trochlea and to create a new groove with normal depth, thus optimising patellar tracking. Associated abnormalities should be specifically treated. Recurrence of instability is very rare after this procedure and is more likely to result from missed associated abnormalities. Although results seem very good in terms of instability, further evidence is still needed since the groups of patients in the published series are heterogeneous. Trochleoplasty is not indicated for patellofemoral arthritis or pain. As any surgical procedure, sulcus deepe...

To ascertain what effect a static magnetic intramedullary device implanted in the rabbit femur had on fracture healing, 20 male New Zealand white rabbits with magnetic/nonmagnetic intramedullary implants were examined histologically, radiologically and for bone mineral density. Three groups were constituted according to the poles of the magnets. During surgery the intramedullary device was driven into the medulla. A femoral osteotomy was created with a mini Gigli wire at the centre point of the rod. Radiographs were obtained at the second and fourth weeks. Histological examination and bone mineral density were evaluated at the fourth week. The results of this study verified that ...

The goal of this study was to describe the clinical findings associated with advanced glenohumeral arthritis due to shoulder instability and instability repairs and to present the clinical results and complications of treating this with shoulder arthroplasty. The weighted average Constant score increased significantly from 49.4 to 81.3 points. There was no significant difference in the type of arthroplasty with 35 cases of total shoulder replacements and ten cases of hemiarthoplasty. The rate of complications was 40% (18/45 patients) with 20% (9/45 patients) requiring an operative revision. Patients with ar...

Moreover, we describe a new method to restore ankle stability with a tibiotalocalcaneal arthrodesis using a retrograde hindfoot nail (n = 4) in contrast to tibiotalar arthrodesis with screws (n = 5). The screw fixation failed in two patients due to osteopoenic bone. The crucial benefits of an arthrodesis with a retrograde nail are a stable arthrodesis, intramedullary stabilisation of the tibia and avoidance of extrinsic material in the wound area. An arthrodesis with a retrograde nail is a good alternative for reconstruction after a wide distal fibula resection. The additional arthrodesis of the subtalar joint was not associated with worse ...

We always used a single surgical approach and obtained anatomical reduction in 30% of the whole series of both groups. Four early complications were noted in four patients (20%). We noted no skin complications and the rate of consolidation was 100%. Four patients (20%) developed avascular necrosis of the talus, and at final follow-up seven patients (35%) had undergone secondary surgery. Radiographic analysis showed an osteoarthritis rate of 94% and a malunion rate of 59%. The mean AOFAS score was 66.9/100 and range of motion was systematically decreased. Contrary to undisplaced talar fractures, displaced talar fractures are a therapeutic challenge with many early or late complications. The outcome often revea...

We enrolled 30 patients who underwent THA for osteoarthritis. The median age was 70 years (range, 55–80 years). Patients were clinically assessed using the Harris hip score. Radiostereometric analysis was used to evaluate stem migration at three to four days, six months, one year and two years. We observed a mean subsidence of 0.73 mm at six months, 0.62 mm at one year and 0.58 mm at two years and a mean retroversion of 1.82° at six months, 1.90° at one year and 1.59° at two years.

A retrospective analysis of 447 patients with primary malignant bone tumours, treated between 1985 and 2005, was performed. Multivariate Cox regression analysis was used to investigate the influence of pathological fractures and further independent variables on survival rate. In 52 of the 447 patients, the primary malignant bone tumour was complicated by a pathological fracture. These fractures were more common in malignant fibrous histiocytoma (MFH) of the bone and in the tumour stages IIa/b and III. Ablative surgery was performed in ten p...

Many surgical methods have been described for the treatment of these nonunions including external fixation, intramedullary nailing, arthroplasty, and fixed angle plating. While arthroplasty may have a limited role in the elderly patient with osteoporosis and severe communiution, most nonunions can be reliably treated with revision fixation using a fixed angled device, lag screws, and bone grafting as needed. Fixed-angle plating also has the advantage of stabilising a small distal segment where intramedullary nailing has proven to be less effective. Any surgical intervention must include restoration of the normal mechanical axis of the distal femur for a satisfactory c...

We conducted a prospective study of a new osteotomy combination: “the dual osteotomy”. An open wedge high tibial osteotomy was combined with 1- to 1.5-cm Maquet-like tibial tuberosity anteriorisation. Thirty-four knees in 30 patients underwent surgery, including ten knees in nine male patients and 24 knees in 21 female patients with a mean age of 45 years (age range 34−58 years). All patients...

Our hypothesis was that a bone allograft would provide the osteotomy site bone healing within the expected time. We performed the MOWHTO using a cancellous bone allograft in 310 knees in 284 patients between 2000 and 2005. Internal fixation was achieved with a T-profile AO plate. Preoperative and postoperative radiographic measurements were taken and statistically processed. All patients were followed up for a period ranging from three to eight years, or 5.9 years on average. Implanted cancellous bone allografts ≤9 mm healed within 12 weeks in 90% of cases. With the properly selected patient and surgical technique, use of a...

We compared two types of poly(L-lactic acid) (PLLA) scaffolds for use in tendon regeneration, a plain-woven PLLA fabric (fabric P) with a smooth surface only and a double layered PLLA fabric (fabric D) with a smooth surface on one side and a rough (pile-finished) surface on the other side. These two types of fabric were implanted into the back muscles of rabbits and evaluated at three and six weeks after implantation. Histological examination showed collagen tissues were highly regenerated on the rough surface of fabric D. On the other hand, liner cell attachmen...

Our objective was to compare postoperative ADL in patients who underwent THA using a head diameter of 26 mm or 32 mm. We assessed the range of motion and the mode of ADL after cementless primary THA. Comparison was performed between 25 joints of 24 patients who underwent THA with a 26-mm femoral head (26-mm group) and 24 joints of 20 patients with a 32-mm head (32-mm group). The postoperative range of flexion and abduction was significantly larger in the 32-mm group than in the 26-mm group. With respect to th...

Valgus intertrochanteric osteotomy (VITO) alters hip biomechanics and enhances fracture union. The double-angled 120° plate is usually used for internal fixation of the osteotomy. It allows the osteotomy to heal with medialisation and verticalisation of the femoral shaft. This deformity causes medial ligament strain of the knee joint, genu valgum and ultimately osteoarthritis. This work presents our experience in treating vertical fractures and non-unions of the femoral neck by VITO and fixation by a single-angled 130º plate. Thirty-six patients presented with 19 recent vertical femoral neck fractures, and 17 non-unions were included. They were 26 men and ten women, and their...

Maintaining acceptable reduction is not always possible, and re-displacement or re-angulation is the most commonly reported complication. Factors leading to this complication can be broadly divided into three groups: fracture-, surgeon- and patient-related. The quality of casting has been historically measured subjectively. The description of several casting indices by different authors has been a major undertaking, attempting to address objective assessment of this factor. The following have been described: cast index, padding index, gap index, three point index a...

We performed a matched-pair study comparing 48 computer-assisted THR with 48 THRs performed using a traditional freehand alignment method. The same implant with a straight non-modular femoral stem was used in all cases. The navigation system used allowed the surgeon to monitor both acetabular cup placement and all the phases of femoral stem implantation including rasping. P...

As per Bryan and Morrey classification, there were seven type I fractures, one type II fracture, three type III fractures, and three non-unions. Patient outcomes were evaluated using the Mayo elbow performance score. The follow-up period ranged from three to seven years (mean 4.8 years). All patients had a stable, pain-free elbow with good range of motion at follow-up. There was no evidence of avascular necrosis or degenerative change.

Results for the osteotomy group were satisfactory in 96.5% of cases. In one patient loosening of the implant occurred after 37 months, which required prosthesis revision. Three patients underwent a further operation of secondary patella resurfacing for patella pain. The group without osteotomy reported a similar percentage of satisfactory results.

Application of AGF was presumed to improve implant fixation and gap healing of non-grafted, loaded implants. We inserted one loaded titanium implant intra-articularly in each medial femoral condyle of eight dogs. Each implant was surrounded by a 0.75 mm gap. One implant in each dog was coated with AGF prior to implantation whereas the contralateral implant served as a control. AGF was prepared by isolating the buffy-coat from blood and further concentrated using an Interpore Cross UltraConcentrator. Platelet counts were increased from a median baseline of 168×103/μl to 1003×103/μl in AGF. However, AGF had no significant effect on implant fixa...

We evaluated the reproducibility of this technique in a regional hospital. Thirty-five patients underwent MIPO of humerus shaft fractures. Fifteen patients had an open fracture, six a preoperative radial nerve palsy, and nine a concomitant thoracic, musculoskeletal or vascular injury. At an average 12-month follow-up, 91% of fractures healed after a mean of 12 weeks (range, 8–16). Two infections occurred. Final alignment averaged 4° of varus (range, 5° of valgus to 20° of varus).

Despite the good number of studies available, comparison and pooling of the results are challenging because of the different evaluation systems and techniques used. However, in general, published studies on HTO report good long-term results with a correct patient selection and a precise surgical technique. Based on our findings, the ideal candidate for an HTO is a young patient (<60 years of age), with isolated medial osteoarthritis, with good range of motion and without ligamentous instability. Furthermore, the literature review shows that the outcomes gradually deteriorate with time. N...

Twenty four arthroplasty surgeons were surveyed to rank the value of RRRs. Since RRRs were primarily valued for educational purposes, we examined the ability of 49 orthopaedic trainees to determine the coronal alignment of TKA performed in cadaveric specimens based on these radiographs in neutral, 10° internal and external rotations. Surgeons rated the quality of the RRRs to be significantly lower than the radiographs taken in the radiology suite (5.5 ± 2.5 versus 8.9 ± 0.9, p < 0.0001). Of an estimated 65,910 TKAs performed by these surgeons, only eight cases (0.01%) required same day revision based on the RRR.

Minimally invasive osteosynthesis, if possible, offers the best possible option as it permits adequate fixation in a biological manner. Seventy-nine consecutive adult patients with distal tibial fractures, including one patient with a bilateral fracture of the distal tibia, treated with locking plates, were retrospectively reviewed. The 4.5-mm limited-contact locking compression plate (LC-LCP) was used in 33 fractures, the metaphyseal LCP in 27 fractures and the distal medial tibial LCP in the remaining 20 fractures.

Clinical and radiographic examinations of 56 knees were carried out at five (4–7) years. American Knee Society (AKS) scores improved from mean 45.5 (20–80) points (knee score) and 55 (15–100) points (function score) before surgery to 90 (30–100) points in both scores after surgery. The position of each implant was determined on screened radiographs using an image intensifier. The implant position was analysed according to the Oxford X-ray rating system. We evaluated nine measures, and there was no detectable correlation between implant position and clinical result. Howev...

A total of 48 patients divided into two groups of 24 were studied retrospectively and prospectively. The retrospective studies revealed that failure to locate distal locking slots in ten antegrade nailing procedures was due to wrong entry point and comminution of the fracture. The challenges encountered led us to innovating methods to overcome the difficulties of placement of distal screws in a prospective study. Application of methods A and B made location of the distal slots easier in the prospective study even though there were more complex comminuted fractures. The methods also reduced the antegrade operation time by 1 hour 11 minutes...

Twelve patients with fresh patellar tendon rupture were included in the study. They were prospectively followed up for an average period of 45 months. The patients resumed their pre-injury activities at an average of 6.1 months. The active knee movement averaged 0–154.6° compared to 0–156.7° in the contralateral knee. Radiologically no patella alta, patella baja or degenerative changes in the patellofemoral joints were noted. The results support use of the absorbable reinforcement device for tension regulation at the suture line. Content Type Journal ArticleCategory Original PaperDOI 10.1007/s00264-009-0879-xAu...

We used a porous beta-tricalcium phosphate (β-TCP) wedge because it is resorbable and osteoinductive. All osteotomies were completely consolidated and complete osseointegration of the remnant of the β-TCP wedge took place. However, after a mean maximum follow-up of ten years none of the cases showed complete resorption. After ten years, 40 (81%) of the 53 knees had an excellent or good result, and in 13 knees there was recurrent pain for which six had an arthroplasty. Although the results deteriorated with time, t...

From 2003 to 2007, 1,150 patients who had acute unilateral intertrochanteric fractures of the femur were enrolled to the study. All fractures were managed by closed reduction and internal fixation with 135° DHS devices. Patient demographics, fracture patterns, reduction and fixation and perioperative course parameters were all recorded. The follow-up period was 38 months on average (range 16–60 months). Finally, 937 patients were available for evaluation of final results in which we focused on lag-screw cutout. Excluding complications not related to screw position, 64 patients (6.8%) with scre...

Fifty-seven knees (29 left, 28 right) of 45 patients (19 boys, 26 girls) were followed-up for a period ranging from 30 to 38 years in seven patients with seven knees, from 20 to 29 years in nine patients with 11 knees, and from ten to 19 years in 29 patients with 39 knees. Supracondylar femoral osteotomy was performed on 12 knees (11 patients), high tibial osteotomy above the tibial tuberosity on eight knees (six patients) and below the tuberosity on 37 knees (28 patients).

Between 2004 and 2007, 29 patients with a mean age of 24.4 years (range 18–42) had ankle arthrodesis using an anteriorly placed narrow DCP. Twenty-two patients were post-traumatic and seven were paralytic (five after spine fracture and two after common peroneal nerve injury). Follow-up was between 12 and 18 months (average 14 months). A rate of fusion of 100% was achieved at an average of 12.2 weeks. According to the Mazur ankle score, 65.5% had excellent, 20.7% good and 13.8% fair results. Ankle arthrodesis using an anteriorly placed narrow DCP is a good method to achieve ankle fusion in many types of ankle arthropathies. Content Type Journal A...

There were 20 male and 21 female patients with a mean age of 74 years. Thirty-two patients were followed up for more than one year and their final results were evaluated. There were 30 stable (31A1) and only two unstable (31A2) fractures. The average surgical time was 28 minutes, the average length of incision was 5.5 cm. All the patients, with one exception, healed without complications in anatomical position with good function of the hip joint. The only complication was caused by pulling-out of the plate from the femur in the fourth postoperative week when the patient (31A2 fracture) fell out of bed. A DHS with a four-hole side-plate was used at r...

The patients were followed for a mean of 35.8 months. No patient was lost to follow-up. Anterior plating of humeral shaft nonunion via an anterior approach was performed using a straight plate and compression for well-vascularised non-unions and wave plating with a tricortical graft for poorly vascularised non-unions. All non-unions healed within 6–18 weeks (mean, nine weeks) without local complication. One patient had a mild decrease in elbow and shoulder range of motion. No neurovascular injury was observed. Anterior plating is a simple, safe and effective treatment for humeral shaft non-union. As this approach avoids the ...

Even today, it has an important role to delay the need for hip replacement in younger patients. The purpose of this study was to evaluate the long-term results of intertrochanteric varus osteotomy for dysplastic osteoarthritis of the hip. Between 1980 and 1995, 52 hips with dysplastic osteoarthritis underwent an intertrochanteric varus osteotomy. All patients could be followed up after 17.8 years. Radiographic assessment included centre-edge (CE) angle of Wiberg and collodiaphyseal (CCD) angle. Dysplastic hip dislocation was classified according to Crowe.

Especially in severely displaced C-fractures in older patients, non-anatomical reduction leads to a high rate of secondary displacement, residual osseous deformity and only a fair shoulder function. For these cases alternative methods such as prosthetic replacement should be chosen.

We have a cohort of 15 consecutive patients in whom this novel cement spacer has been used. All patients were able to at least partially weight bear and none of the spacers fractured. Thirteen have been explanted at second stage operation after a minimum of eight weeks in situ. Two patients have been unable to undergo a second stage due to unrelated death and medical problems precluding further surgery. The articulating cement spacer described is produced using a technique that is simple, reproducible and allows a reinforced spacer to be created inexpensively without the need for special equipment.

We performed THA in six patients with advanced active tuberculosis of the hip from 2002 to 2006. Tuberculosis was confirmed in all cases by histological examination. All patients were treated with antituberculous medications for at least two weeks followed by thorough debridement and THA. Antituberculous medications were administered postoperatively for at least 12 months. The duration of postoperative follow-up was an average of 49 months. No reactivation of the infection was detected in our series. Using the Harris hip score system, five of th...

An improved understanding of deformation of the metatarsals under inversion landing conditions is essential in the diagnosis and prevention of metatarsal injuries. In this work, a detailed three-dimensional (3D) finite element foot model was developed to investigate the effect of inversion positions on stress distribution and concentration within the metatarsals. The predicted plantar pressure distribution showed good agreement with data from controlled biomechanical tests. The deformation and stresses of the metatarsals during landing at different inversion angles (normal landing, 10 degree inversion and 20 degree ...

The question of which surgical approach is the best for the femoral head fracture and its relationship with HO and AVN remains controversial. We conducted a systematic review in which all published studies were evaluated. We performed a literature search in MEDLINE, PubMed, EMBASE, MD Consult, and the Cochrane Controlled Trial Register from 1980 to April 2009. We found ten appropriate studies, describing 176 patients. A lower percentage of patients treated with a trochanteric flip approach was reported with HO than patients treated with anterior or posterior...

The pelvis and upper femur are frequently involved, resulting in disabling hip disease, and total hip arthroplasty (THA) may be required. We performed a retrospective study on the management and the outcome of 39 uncemented hydroxyapatite fully-coated THA in patients with PDB of the hip. The follow-up averaged 79.4 months (range 24–194). Functional scores improved significantly and, using the Harris hip score, 84% of patients had an excellent clinical outcome at the latest follow-up. Despite one case of an uncemented acetabular component with probable loosening, no implant revision had been...

Based on Allman’s classification, fractures were placed in group Ia, Ib and Ic. The majority (66%) were allocated to groups Ib or Ic. Clinical evaluation was made using the Constant score and simple shoulder test. On post-injury radiographs, we measured the amount of overlapping of the fracture fragments (OV) both in centimetres and as percentage of the length of the clavicle and the mean distance between cranio-caudally displaced fragments (DS). The mean Constant scores were 87.1% and 85.6% in groups Ib and Ic, respectively. In patients with a Constant score ≥90%, the mean OV was 7.7% and the averag...

At the Department of Trauma Surgery, Vienna Medical University, 419 children and adolescent patients with physeal injuries of the distal tibia were treated from 1993 to 2007, of these 376 were included in our study and evaluated retrospectively. Seventy-seven displaced physeal fractures of the distal tibia were reconstructed anatomically by open or closed reduction and produced 95% excellent results. A perfect anatomical reduction, if necessary by open means, shou...

Little information exists about the radiological features of arthrosis in relation to clinical findings and the radiological appearance in degenerative shoulder joint disease especially with regard to decision making about the timing of joint replacement. We retrospectively examined 120 standardised X-rays of patients with advanced osteoarthritis of the shoulder. Exclusion criteria included rotator cuff tear, severe glenoid erosion or protrusion. Measurements of joint space width at three levels in each plane (anteroposterior and axillary view), humeral head diameter and size of humeral osteophytes were made by two independent examiners. Osteoarthritis was graded a...

Between 2004 and 2007, 309 biopsies (ultrasound 151, computed tomography 89, and fluoroscopy 69) were included. There were 142 soft tissue and 167 bony lesions. Diagnostic yields and accuracies were assessed using the chi-square test or Fisher’s exact test with Bonferroni’s correction when necessary. Overall diagnostic yield was 90.6% for all 309 lesions (bone 91.6% vs. soft tissue 89.3%, p = 0.5125). The diagnostic accuracy of the 185 core needle biopsies, which were confirmed by definitive surgical biopsies, was 84.3% (bone 88.9% vs. soft tissue 79.1%, p = 0.0669). The yields of homogenous bone tumours (96.8%)...

Six matched pairs of cadaveric bones were used for each of three bone types of the humerus, radius and ulna. For each bone type, one of two bone plates was fixed to either of two matched cadaveric bones at the middle of the diaphysis. The interface contact area and force of the plate fixed to three types of human cadaveric bones were evaluated using Fuji prescale pressure sensitive film. Data were quantitated using computer-assisted image analysis. Results showed that the average force between the MC-LCP and humerus or radius was about half of that o...

Sixty-two patients underwent 63 proximal femoral replacements for metastatic bone disease over a seven-year period. Breast cancer was the most common primary pathology. One patient underwent a revision procedure for infection. Twenty-two patients suffered dislocations, most commonly those undergoing a conventional arthroplasty articulation. The estimated cost of a proximal femoral replacement is £18,002 at our centre. Less than half of this is reimbursed under Payment by Results. Endoprosthetic replacement of the proximal femur is an effective treatment of metastases, but is poorly reimbursed under current funding arrangements.
