All patients were managed by revision arthroplasty, using cementless femoral stems. Cortical struts, cable plating systems, bone allograft and demineralised bone matrix were used to aid the reconstruction where indicated. All the fractures had clinical and radiological union. The outcome was graded, subjectively as satisfactory by all patients and this is substantiated objectively, by a post operative mean Harris hip score of 83.04. Uncemented revision appears to be an attractive option for periprosthetic fractures with unstable femoral stems. PMID: 20235063 [PubMed - as supplied by pub...

At 1 and 2 years post-operatively, patients with HR achieved statistically significantly better WOMAC functional scores. However, differences in scores were of slight clinical relevance with a difference of 2.2/100 and 3.3/100, at 1 and 2 years respectively (p=0.007). After an average follow-up of 56 months (range 36-72) there were similar re-operation rates 7/100 THA and 6/109 HR (p=0.655) and revision rates 2/100 THA and 4/109 HR (p=0.470).

The classification and management of aseptic loosening of total hip arthroplasty remains a distinct challenge to the modern orthopaedic surgeon. The aim of this study was to assess the inter-observer and intra-observer reliability of commonly used classification systems for the assessment of bone stock loss in revision hip surgery. Radiographs of 23 femoral and 32 acetabular components in 30 patients were assessed using the Paprosky, AAOS and Endo-Klinik classification systems. A novel classification system was introduced and also used to assess the radiographs. Assessment was undertaken by 3 surgeons on 2 separate occasions and the inter- and intra- observer reliability calculated. The nov...

After adequate resuscitation, an angio CT scan of her pelvis showed a false aneurysm of the external iliac artery in proximity to a loose pegged cemented cup. A pelvic X-ray 6 years prior to presentation had revealed a medialized high riding pegged cemented cup with a loose cemented stem. Vascular reconstruction followed by revision of the left THA was necessary.

From 1995 to 2000, 225 total hip arthroplasties (THA) were performed using this device. All patients were evaluated clinically by the Harris Hip Score, and radiographically. The Hip Score increased from 54 preoperatively to 97 points postoperatively. The stem displayed a varus alignment between 5 degrees and 10 degrees in 17 cases without any clinical consequences (HHS 96.8). We recorded one case of septic loosening and one case of aseptic loosening. The stability of the stem was radiographically evaluated according to Engh's criteria, confirming bone ongrowth in all other cases. ...

We investigated if complications, reoperations and mortality differed from that of cemented hemiarthroplasties. The study groups consisted of 78 cemented and 97 uncemented, hydroxyapatite coated hemiarthroplasties with minimum 1 year follow-up. The dislocation rate was 3% in both groups (p=0.84). Proximal femoral fracturing occurred in 1% in the cemented group and in 4% in the uncemented group (p=0.26). Reoperations were performed following 4% of procedures in the cemented group and following 2% of procedures in the uncemented group (p=0.48). Mortality rates did not differ statistically significa...

Harris Hip Score evaluation showed a significant improvement in hip pain and function. Radiographic measurements of axial migration over a 4-year period were less than 2 mm. The migration data were similar across the 4 types of revision stem. A follow-up using DEXA scans showed preservation of bone in all regions up to 4 years, which justifies the design rationale for the close fit of the stems in the proximal region in achieving initial stability and strain tran...

The cartilage is macroscopically normal but disrupted from the subchondral bone. Excision of chondral flaps is the usual procedure for this type of lesion. However, we report 19 consecutive patients in whom the delaminated chondral flap was re-attached to the underlying subchondral bone with fibrin adhesive. We used the modified Harris hip score for assessment of pain and function. Improvement in pain and function was found to be statistically significant six months and one year after surgery. No local or general complications were noted. Three patients underwent further surgery for unrelated reasons. In each, the area of fibrin repair appeared intact and secure. Our results suggest...

Cambridge cups were implanted in a cohort of 50 women who presented with displaced sub-capital fracture of the femoral neck. The cups were manufactured with an hydroxyapatite (HA) coating. Twenty six cups were implanted after removal of the HA. Twelve Cambridge cups were retrieved post-mortem between two and 84 months after implantation. Histological and histomorphometric testing was undertaken to analyse the residual HA coating thickness, bone apposition to the implant surface and particulate wear debris in the surround...

After extracting the proximal part of the femoral component, the femoral canal was opened at the knee joint and a modified intramedullary nail was used to dislodge the distal stem under fluoroscopic control. In five cases the surgery was uneventful. In one case femoral perforation occurred due to the contour of the cement mantle at the tip of the stem. In the postoperative period all patients progessed well. Removal of a broken stem using our method has limited indications, and it is not recommended in septic cases or when the cement mantle at the tip of the stem has an oblique contour. It also requires opening of the knee joint, but the technique is simple, saves surgical time and...

Anatomic abnormalities and the young age of the patients influence the results. Restoration of the anatomic hip center often requires shortening of the femur in order to avoid over-stretching of neurovascular structures. We performed cementless total hip arthroplasty with subtrochanteric transverse osteotomy on 44 hips in 31 patients. There were 29 female and 2 male patients.

Patient-reported outcome and satisfaction scores have become increasingly important in evaluating successful surgery. This case-matched control study compared patient-reported outcome and satisfaction data following hip resurfacing and total hip arthroplasty. Thirty-three consecutive patients selected for hip resurfacing were compared with 99 patients undergoing cemented total hip replacement (THR), matched for age, sex and pathology. Participants completed a Short-Form 12 Health Survey (SF-12) and Oxford Hip Score questionnaire preoperatively and 6 months post operatively with an additional patient satisfaction questionnaire. There was no difference in length of hospital stay. While both groups reported improved ...

Standardised antero-posterior radiography was performed on two groups of 30 patients with unilateral primary osteoarthritis undergoing either a cemented total hip or resurfacing. The normal contra-lateral hip was used as the control. Leg length and offset were measured pre-operatively with no significant difference between the two groups. Cup offset, femoral offset, total offset and leg length of the prosthesis and normal side were measured by two observers and mean measurements were analysed by a paired t test.

We studied 89 patients who underwent total hip replacement for primary unilateral osteoarthritis. Lateral pelvic X-rays that included the hips were performed pre-operatively and one year post-operatively. Reference values were calculated by carrying out the same analysis in 100 asymptomatic healthy volunteers. Pelvic orientation was analyzed using the sacral slope. Patients having surgery for osteoarthritis had a decreased pelvic range of motion pre-operatively and post-operatively when compared to healthy volunteers. Post-operatively, this range of motion increased by 3 degrees but remained lower than the norm. Compared to asymptomatic healthy volunteers...

Leg length discrepancy may occur following total hip arthroplasty, with a potentially impaired functional outcome as a result. The aim of this study was to compare the leg length discrepancy between both cemented and uncemented femoral stems when used in total hip arthroplasty. A prospective radiological study of 200 consecutive primary total hip arthroplasties was performed between June 2005 and December 2006. Pre and post-operative radiographs were analysed. 56 (56%) of the total hip arthroplasties where an uncemented femoral stem was used had a leg length discrepancy over 1 cm. However only 23 (23%) of the total hip arthroplasties with a cemented femoral stem had a leg length discrepancy over 1 cm. The use of cemented femoral ...

Arthritis of the hip primarily involves the joint surfaces. Intuitively the principal objective in the surgical management of arthritis is to replace the damaged articular surfaces. However, early attempts at conservative replacement failed both because of inadequate fixation and failure of the articulation. Conservative hip implants take less bone at the time of surgery and preserve bone in the longer term with more physiological loading. In addition, the implants are usually easier to insert with soft tissue sparing surgery. While these implants potentially offer an additional option in the surgical management of younger patients with arthritis, this advantage is negated if there is an unacceptably high incidence of premature failure.

There are no published clinical results of this approach used for resurfacing arthroplasty. One hundred consecutive patients were assessed prospectively for a minimum follow-up of 2 years (range 2-5 years). The Oxford Hip Score fell from a median of 30 pre-operatively to 5 at two years. Similar improvement was found in the UCLA Activity Score. There were no cases of component failure or fractures. However, nine patients had minor complications related to the osteotomy.

Significant variability in the clinical presentation and degree of deficiency is common. Current management strategies aimed at improving functional ambulation are largely dependent on the degree of femoral shortening and the status of the hip and knee joint. Treatment of acetabular deficiency and proximal femoral deformity in cases of PFFD must be individualised. Reconstruction of the hip joint with pelvic and femoral osteotomies may be possible in mild cases of PFFD. Stability of the hip and knee joint must be achieved prior to consideration for limb lengthening strategies. Severe cases of PFFD may b...

Median length of follow-up was 7.1 years (5 to 13). There was one dislocation, and one peri-prosthetic fracture. There were no revisions for infection, acetabular erosion or stem loosening. Twenty-six patients had died by the time of final follow-up with an overall 5 year cumulative survival of 60.2%. Thirty day mortality was 36% in patients with an ASA score of 3. We present excellent clinical and radiological medium to long term results with no evidence of acetabular erosion. However, careful patient selection is necessary to avoid high early mortality rates.

It is, however, traditionally offered to the younger age group of patients, largely those aged under 60 years. We studied 42 consecutive patients (42 hips) aged 60 years or over (mean age 64) and 41 consecutive patients (42 hips) under this age (mean age 49), all of whom had undergone a metal-on-metal hip resurfacing arthroplasty. A modified Harris hip score was translated to QoL scores using the Rosser Index Matrix immediately pre-operatively, and at six weeks, six months, one year and four years after surgery.

A fatal fat pulmonary embolism immediately followed removal of the femoral head, prior to further preparation of the acetabulum or femoral shaft. Fat embolism syndrome is a well-known complication during total joint arthroplasty, usually attributed to preparation of the femoral shaft, particularly intramedullary reaming and insertion of the prosthesis. These risk factors have previously been identified in the literature. We believe that this case highlights the need for further research to establish the intramedullary pressures during the processes of dislocation and resection of the femoral neck and the attendant risk.

Bone mineral densities were compared with the unoperated side at a time interval of eight years between scans using dual energy X-ray absorptiometry. Initial proximal stress shielding is known but we show that this response continues into the medium to long term in relative terms. We have also found an overall trend for bone mineral density to increase around the prosthesis with the greatest changes occurring distally. The greatest real increase in bone mineral density occurred in Gruen zones 2, 3 and 5 with smaller increases in zones 1, 4, 6 and 7. However, when compared with the contralateral unop...

Of the available options the Birmingham Hip Resurfacing (BHR) prosthesis has been the most popular choice in this country. Despite this revision rates have been shown to be higher in the resurfacing group compared to the total hip arthroplasty group particularly in the early postoperative period. Revision of the BHR acetabular component is technically demanding due to several unique design features of this component.

One hundred and twenty-two procedures were performed on 107 patients between 1996 and 2005. An initial audit (22 procedures) revealed high wastage (45% returned) of allogenic blood. A predonation protocol was initiated and subsequently 100 procedures in 91 patients wer...

It also affects polyethylene wear and the rate of osteolysis. Although there are many tools available to the surgeon to aid placement of the acetabular component, errors still occur, especially in version. We conducted a study of 14 cadaveric hips to investigate whether the transverse acetabular ligament can be used to align implanted cups with the correct degree of anteversion. Radiographic measurement revealed that all of the implanted cups were found to lie within the 'safe zone' for anteversion, when aligned with the ligament. PMID: 18645967 [PubMed - in proc...

In this cadaveric study, anteversion was modelled radiographically with a Charnley double wire marker Long Posterior Wall (LPW) cup and the position of the long posterior wall was studied with relation to different anteversion angles, and also correlated with computer generated line diagrams of the acetabular cup. The position of a long posterior wall varies when different types of anteversion are applied. By increasing the operative anteversion the long posterior wall comes to lie inferiorly and the advantage of the long posterior wall is lost. In light of prior confusion with definitions and in an attempt to make the terms more relevant to the ...

Porous tantalum acetabular shells may represent an improvement from conventional porous coated uncemented cups in revision acetabular reconstruction associated with severe acetabular bone defects. We reviewed the results of 46 acetabular revisions with Paprosky 2 and 3 acetabular bone defects done with a hemispheric, tantalum acetabular shell and multiple supplementary screws. At a mean follow-up of 40 (24-51) months, one acetabular shell had been revised in a patient with a Paprosky 3B defect. Cementless acetabular revision with the tantalum acetabular shell demon...

The most frequent preoperative diagnosis in our patients were severe hip arthrosis (50%), and rheumatoid arthritis (15%).The mean follow up was 8.6 years (range 2-15 years). The most frequent long-term complication was the appearence of radiolucent lines.A cemented acetabular cup was used in all cases. Preoperative mean Harris Hip Score was 42.3, rising to 90.6 at follow-up after surgery.

Two groups of screws (n=8) were inserted into Trabecular Metal revision shells (Zimmer), into which PE liners were then cemented. Screws in Group 1, inserted in the shell's pre-fabricated holes, were countersunk, whereas screws in Group 2 were inserted in custom-drilled holes that make their heads protrude into, and interdigitate with, the overlying cement mantle. Perpendicular loading was then applied to the screw shafts both statically to failure and cyclically. A greater stiffness was observed for the protruding screws upon static loading; and while the countersunk screws all failed at the screw-cement junction (53.44 +/-...

Plain radiographs revealed gas shadows in the region of the wound. An intra-operative sinogram showed the sinus to be coming from a pelvic diverticular abscess and the hip to be an innocent bystander. Our case emphasises the importance of having a clear preoperative plan with relevant investigations before a radical operative procedure is undertaken, to avoid unnecessary risk to a non-infected hip prosthesis.
