Humerus is a common site for malignant tumors. Advances in adjuvant therapies and reconstructive methods provide salvage of the upper limb with improved outcomes. Reports of limb salvage with total humeral replacement in extensive humeral tumors are sparse. We undertook a retrospective study of 20 patients who underwent total humeral endoprosthetic replacement as limb salvage following excision...

BACKGROUND To evaluate the clinical outcome of revision of primary shoulder replacement by using reverse total shoulder arthroplasty (RTSA). METHODS Seven patients underwent revision RTSA with a mean follow-up of 22.1 months (range, 12 to 54 months). Their mean age at the time of operation was 75.5 years (range, 70 to 80 years). Assessments were performed on the preoperative and postoperative...

PURPOSE To evaluate the influence of patient characteristics on stem loosening after cemented or uncemented total hip arthroplasty (THA) using a matched case-control study. METHODS; Consecutive records of 4372 cemented (716 cases and 3656 controls) and 809 uncemented (115 cases and 694 controls) primary THAs between 1981 and 2003 in 30 hospitals in 8 European countries were reviewed. Cases and ...

BACKGROUND Overweight and a high level of physical activity are known risk factors for loosening of a total hip arthroplasty (THA) due to primary osteoarthritis. We wanted to investigate how these factors, together with age and sex, affect the risk of revision surgery. PATIENTS AND METHODS We matched data from the Norwegian Arthroplasty Register with information on risk factors collected at a...

BACKGROUND The most common modes of failure for megaprostheses are aseptic loosening followed by periprosthetic infection and stem fracture. Surgical technique for bone and implant exposure is controversial and may influence the success of revision and the need for additional future revisions. The purpose of this study was to evaluate the effectiveness of cortical fenestration for megaprosthesi...

OBJECTIVE To analyze the outcomes of total elbow arthroplasty in the treatment of elderly type C distal humeral fractures and discuss the clinic efficacy. METHODS 8 cases of elderly type C distal humeral fractures, Male was in one case, female in seven cases, and the average age was 66.5 years (60-81). All cases were closed fractures because of falling and none had associated injuries. Accord...

Glenoid morphology has an important impact on outcomes and complication rates after shoulder arthroplasty for primary glenohumeral arthritis. The B2 glenoid, or a biconcave glenoid with posterior humeral head subluxation, in particular has been associated with a poorer outcome with shoulder arthroplasty compared with other glenoid types. A variety of techniques may be used to address the bone d...

The increase in the number of shoulder arthroplasties has also created a paradoxical increase in the number of revision procedures. These revision surgeries can be complicated by well-fixed humeral components that require removal. In this article, we report a representative revision arthroplasty that involved a novel technique, vertical humeral osteotomy, which allowed for safe and effective hu...

Between 1993 and 2002, 58 GSB III total elbow replacements were implanted in 45 patients with rheumatoid arthritis by the same surgeon. At the most recent follow-up, five patients had died (five elbows) and six (nine elbows) had been lost to follow-up, leaving 44 total elbow replacements in 34 patients available for clinical and radiological review at a mean follow-up of 74 months (25 to 143). ...

PURPOSE To investigate the cause of failure in matte-surface cemented stems in second-generation metal-on- metal total hip arthroplasty (THA). METHODS Records of 26 men and 11 women (39 hips) aged 29 to 72 years who underwent primary cementless THAs by a single surgeon using second-generation metal-on-metal prostheses and were followed up for a mean of 122 (range, 120-141) months were reviewe...
