Efforts to treat it with the use of local anesthesia have been made, but the results have been contradictive. In the late 1990s, an infiltrated solution of ropivacaine/ketorolac/adrenaline was shown to be effective for this purpose, and this technique has since spread over the world. The purpose of this study was to compare the local infiltration anesthesia technique with epidural anesthesia, which has been the most widely used technique in Sweden.Eighty-five patients received either local infiltration anesthesia or epidural anesthesia for postoperative pain relief. Postoperative morphine consumption, range of motion, walking ability, ...

A total of 130 patients (70 hips, 60 knees) received a modified FFbH-OA survey with 6 additional questions concerning patients' expectations before and 3 years after joint replacement surgery. The overall response rate was 78.8% (101 patients). Patients who underwent THA had a mean age of 63.7 years, and those who underwent TKA had a mean age of 67.4 years.Sixty-three percent of all respondents reported that their expectations had been fulfilled or exceeded 3 years postoperatively (THA, 65%; TKA, 61%). A high negative correlation in the THA group could be seen between patients' expectations and clinical scores: the lower the clinical score, the less the patient's expectations...

Currently up to 70% of combat wounds are extremity related. Clinical outcomes for these patients are dependent on the care of these wounds. The Vacuum-Assisted Closure (VAC) Therapy system (KCI Inc, San Antonio, Texas) is ubiquitous in theater and is often considered the only way to treat these wounds. However, the VAC Therapy system is not without problems. It is expensive and requires extensive amounts of product and machinery, as well as functioning suction, and therefore a power source at all times. In addition, the VAC Therapy system requires a trained and vigilant nursing staff. We hypothesized that the antibiotic bead ...

The indications to discontinue anticoagulation for a simple procedure are controversial. Other surgical subspecialties have shown that keeping patients on warfarin during a simple procedure is safe. The purpose of this retrospective study was to evaluate the postoperative complications encountered for patients undergoing simple arthroscopic procedures while on warfarin. We hypothesized that anticoagulated patients undergoing simple arthroscopic procedures would have few surgical bleeding complications.Arthroscopic procedures performed over a 10-year period on warfarin-anticoagulated patients were retrospectively evaluated.

Therefore, we examined whether smoking causes osteoporosis based on the impact of smoke exposure on the bones of rats. A rat model of passive cigarette smoking was prepared by breeding rats in a cigarette-smoking box for 4 or 8 weeks. Histological changes, micro-computed tomographic (CT) analysis, mechanical bone strength, and bone mineral density of the femur and lumbar vertebrae were examined in these rats and in control rats that were not exposed to smoke.

The polished, tapered cemented femoral stem is vulnerable to displacement when exposed to traction forces. Six days after bipolar hemiarthroplasty, the patient experienced her first dislocation, and immediate reduction of the dislocated hip was easily achieved. However, on the ninth postoperative day, redislocation occurred, and this time, reduction was not achieved.

Forceful reaming and insertion of the nail led to a break in the cortex of the distal fragment and bending of guide wire. Finally, open reduction and intramedullary nailing was performed to retrieve the guide wire and intramedullary bone fragment and fix the tibia.A comminuted fracture with multiple close fragments in proximity to the fracture site should be preoperatively scrutinized to look for intramedullary bone fragment or a fragment that could be pushed in the intramedullary canal during the intramedullary nailing.

Tsuge reported a new surgical technique for debridement arthroplasty using a posterolateral approach to the elbow in 1987. He has also reported using this procedure during arthroplasty for posttraumatic stiff elbow and for synovectomy in rheumatoid arthritis. This approach permits easy dislocation of the elbow and provides a good view of the whole joint. Although the recurrence rate of PVNS of the elbow is high, our patient has retained good elbow function with no evidence of local recurrence at 30 months postoperatively.

Using the screw paths associated with an anteroinferior plate (anteroinferior to superoposterior), the distance from the posterior clavicle cortex to the nearest vital structure was measured at 5 different positions along the clavicle. In the medial half of the clavicle, the subclavian artery is in closest proximity to the clavic...

In the absence of residual fibers at the insertion, proper placement requires knowledge of the anatomic relationships in the proximal humerus. This anatomic study attempts to measure these relationships and the dimensions of the insertional footprint to assist in surgical repair and reconstruction. Six matched pairs of cadaver proximal humeri were examined. All specimens were found to be in good condition and none were excluded. The proximal to distal length and maximum width of the pectoralis major tendon were measured at the humeral insertion with a digital caliper.

Intra-articular primary synovial chondromatosis in the knee joint may be localized or generalized. The symptoms associated with localized synovial chondromatosis may include diffuse pain, swelling, restricted motion, crepitus with symptoms of locking and giving way, and posteromedial tenderness mimicking medial meniscus tear. Diagnosis is usually established with magnetic resonance imaging (MRI) and confirmed by histological examination. To our knowledge, synovial chondromatosis of the knee joint in the posteromedial corner has not been reported in the literature. ...

In patient 1, PVNS was suspected on radiographs but confirmed only after removal of a mass of thick, grey-brown spotted synovia. A complete synovectomy was performed prior to hip resurfacing. Seven years postoperatively, radiographs show secure fixation of the components with no radiolucencies. In patient 2, arthroscopy of the hip joint had been performed 3 months prior, but PVNS had not been diagnosed. Pigmented villonodular synovitis was confirmed during the operation when incising a yellowish nodular mass protruding from the capsule. Granuloma was also found in the inferior and anterior part of the acetabulum. Four years postoperatively, the patient exhibits excellent clin...

Minimal information is available regarding the clinicopathologic characteristics of the 4 hibernoma variants: typical, lipoma-like, myxoid, and spindle-cell. Spindle-cell hibernoma is believed to be the rarest variant, accounting for approximately 2% of hibernomas. The spindle-cell variant predominantly develops in the fourth and fifth decades, with an average age at diagnosis of 42.5 years (range, 28-59 years). It has a male predilection of 4:1.

Spine fractures are common and represent up to 16% of traumatic fractures. Diagnostic imaging currently involves plain films and computerized tomography, but MRI is being used with increasing frequency. The definition of neurologic tissue injury has had substantial documentation in the spinal literature. Clinically, posterior ligamentous complex injury has been associated with facet disruption, gapping of the spinous processes, and significant kyphosis. Assessment of spinal stability in the spine trauma population is based significantly on the assumed disruption or integrity of the posterior ligament...

Dislocations can result from sporting activities or higher-energy mechanisms such as motor vehicle accidents or falls from a height. Subtalar dislocations can often be reduced in the emergency room setting, but irreducible dislocations have been described that require operative management. Overall, treatment of isolated subtalar dislocations results in favorable outcomes for patients albeit with some expected reduction in subtalar motion and an increased incidence of subtalar arthritis.

The incidence of this disorder is relatively low, especially with oral therapy, but may result in extensive ulceration, pain, mucosal inflammation, and altered sensation in the maxilla or mandible. Multiple risk factors have been determined and should be considered when initiating a patient on bisphosphonate therapy. Although treatment is generally supportive, additional surgical measures, including debridement and resection, may need to be taken for more extensive disease.

The socioeconomic costs associated with revision surgery and reverse total shoulder arthroplasty increasingly strain the health care system. Rotator cuff pathology treated at an earlier stage, when the tears are smaller and the biology conducive to healing, is associated with a more durable repair and improved strength of the shoulder. Identifying and treating full-thickness rotator cuff tears when they are smaller and nonretracted and before permanent neuromuscular changes develop could potentially improve the quality of patient care while decreasing complications and costs.

There is increasing demand for more efficient and safe rehabilitation protocols. This randomized prospective study evaluates the need for hip restrictions following a modified anterolateral procedure. From 2004 to 2008, 81 patients seeking elective THRs were randomly assigned into a standard rehabilitation group or an early rehabilitation group. The standard group included restrictions to avoid hip flexion >90 degrees and avoidance of riding in a car for the first postoperative month.

Arthrosis at each level was graded from 0 to 4 on a continuum from no arthritis to complete ankylosis. These results were then examined in relation to interfacet spread. Interfacet distances were measured at each level (L1-S1). The difference in interfacet spread (L4-S1) was then correlated to facet arthrosis and disk degeneration. In individuals younger than 50 years (n=251), increased interfacet spread (L4-S1) was associated with less facet arthrosis at the L5/Sl level (P<.05).

Wiring techniques are cumbersome and cable grip fixation has an unacceptable rate of non-union, cable fraying, and production/migration of third-body debris. Using 4 case examples, we present a novel and straightforward locking plate technique that we currently use to achieve such fixation. This method also allows placement of bulk allograft that may restore trochanteric bone stock in cases of marked osteolysis. The technique uses implants that are readily available, and can be employed not only in fixation of trochanteric osteotomy but also in trochanteric advancement. At a minimum of 20 month...

It usually develops at the metaphysis of the long bones, especially the distal femur and proximal tibia. Approximately 40% of osteochondromas are found around the knee. Osteochondroma commonly presents as a painless mass and is incidentally identified via plain radiographs. Thus, surgical excision is not routinely recommended unless the tumor causes clinical symptoms or cosmetic distress.Osteochondroma located in the pelvis is unusual. Spinal nerve root compressions due to pelvic osteochondroma are also rarely reported. We assessed the solitary pelvic osteochondroma of a 33-year-old man mimicking spinal disease.

After emergent extrication of the intrathoracic humeral head and proximal medial shaft, the patient underwent delayed shoulder reconstruction with a reverse total shoulder arthroplasty and allograft augmentation. The reverse shoulder was used due to the high-energy comminution, stripping of the remaining tuberosity fragments, and extensive proximal bone loss. The patient's functional ability would therefore depend on the biomechanical design of the prosthesis and not solid healing of the severely compromised tuberosity pieces. The proximal shaft was reconstructed using a femoral strut allograft that was cabled into place. This...

Initially, the patient, a 36-year-old woman, had been misdiagnosed with fibrous hyperplasia of the left humerus. We intended to curette the lesions and transplant fibula to fill the bone defect, but the initial surgical attempt could not be completed due to massive intraoperative bleeding. In the second surgery, she was treated by blocking the blood flow of the subclavian artery temporarily through a balloon catheter, curetting lesions, and filling the defect of bone with bone cement and K-wires. At 12-month follow-up, there was no evidence of local recurrence of hemangioma or loosening of bone cement. However, longer-term follow-up is needed to confirm the success of the ...

It is locally aggressive, and local recurrences are described after resection. Pain is the most common symptom. Since the lesion is typically slow growing, the pain can be present for many years before the patient seeks medical attention. Microscopically, adamantinoma consists of islands of epithelial cells in a fibrous stroma. Nuclear atypia is minimal, and mitotic figures are rare. The most common radiographic appearance is that of multiple sharply demarcated radiolucent lesions surrounded by areas of dense, sclerotic bone. This tumor most often affects the tibial diaphysis and produces lytic lesions that can cause fractures.A...

He sustained a right hip dislocation and transverse with posterior wall acetabular fracture with a nonconcentric hip joint after reduction. The fracture was treated with right labral and articular segment absorbable suture tie-down and relocation of the right hip into an anatomical position. At 32-month follow-up, the patient had returned to activities of daily living, he had a normal and symmetric gait pattern, and no pain on hip adduction, flexion, or internal rotation.

SW1353 cells were stimulated with S-nitroso-N-acetyl-D,L-penicillamine, expressions and activities of metalloproteinase-13, and membrane type-1 metalloproteinase were assayed, and a proteolytic activation of recombinant human metalloproteinase-13 was measured in the presence of recombinant human membrane type-1 metalloproteinase. Nitric oxide increased expressions of both matrix metalloproteinases and stimulated the proteolytic processing of metalloproteinase-13 from the pro-enzyme to the final active form.

The purpose of this randomized, controlled study was to determine which factors are predictive of postoperative range of flexion. Fifty-six patients received either a standard or a high-flexion design NexGen Legacy Posterior-Stabilized TKA (Zimmer, Warsaw, Indiana). The relationship between preoperative flexion, intraoperative flexion, and range of flexion 1 year postoperatively was determined. The influence of soft tissue release and the type of femoral component was also investigated. A significant correlation existed between preoperative flexion, intraoperative flexion, and maximum flexion 1 year postoperatively. Patients who had a p...

However, patients with extra-articular deformities, severe varus and valgus deformities, and posttraumatic arthrosis pose unique challenges to surgeons. Each deformity requires different modifications of surgical technique or prosthesis used to successfully perform TKA and optimize postoperative results. The surrounding tissues connect the femur and the tibia at the anterior, posterior, medial, and lateral walls of the knee joint. The medial soft tissues should be released for varus deformities and lateral soft tissues should be released for valgus deformities. The posterior soft tissue may be released for flexed de...

Ten cadaveric hips in 6 whole-body specimens were used, with 3 fiducial markers to allow registration of computer navigation points to computed tomography scan data. Three femoral neck resection levels were investigated: 0 mm, +5 mm (the recommended level of resection), and +10 mm from the base of the femoral neck. Results showed that the CCD angle was significantly higher with 0-mm neck cut and the offset was lower, whereas the highest neck cut had longer leg-length results.

We evaluated 112 knees treated with TKA using the gap technique and navigation system. Flexion-extension gaps were measured before femoral cutting (precutting gaps) and before prosthesis insertion (final gaps). Balanced precutting flexion-extension gaps were shown in 45 cases (40.2%), and balanced final flexion-extension gap was achieved in 105 cases (93.8%). Precutting tight extension gaps resulted from preoperative extension lag. We found TKA using the gap technique with navigation to be an effective means of achieving balanced flexion-extension gaps.

NASA has established benchmark figures for different manufacturing processes, and we have used these figures in analyzing our first 240 navigated total knee arthroplasties for varus knees. Our experience curve was 93% (P < .001), which is similar to the experience curve (90%) for processes consisting of 25% hand assembly and 75% machining.
