Between January 1, 1976 and December 31, 1991, 195 total shoulder arthroplasties and 108 hemiarthroplasties were performed in 247 patients in patients with rheumatoid arthritis. One hundred and eighty-seven total shoulder arthroplasties and 95 hemiarthroplasties with complete preoperative evaluation, operative records, and minimum 2-year follow-up (mean,(More)
Currently, there is little information on the outcome of humeral head replacement for steroid-associated osteonecrosis of the humeral head. The purpose of this study was to evaluate the outcome of patients who underwent humeral head replacement for steroid-associated osteonecrosis to determine the results, risk factors for an unsatisfactory outcome, and(More)
This study was performed to review the safety and outcome of total shoulder replacements in patients who are > or = 80 years of age. A total of 50 total shoulder replacements in 44 patients at a mean age of 82 years (80 to 89) were studied. Their health and shoulder status, the operation and post-operative course were analysed, including pain, movement,(More)
BACKGROUND C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) have been shown to be useful for diagnosis of prosthetic hip and knee infection. Little information is available on CRP and ESR in patients undergoing revision or resection of shoulder arthroplasties or spine implants. METHODS/RESULTS We analyzed preoperative CRP and ESR in 636(More)
There has been significant evolution of total shoulder arthroplasty design and improvement in technique over the past 25 years, but there is no information available as to whether this has translated into lower complication rates or different sorts of complications. The purpose of this study was to determine the contemporary complications and their(More)
BACKGROUND Conventional wisdom suggests that the glenoid defect after a shoulder dislocation is anteroinferior. However, recent studies have found that the defect is located anteriorly. The purposes of this study were (1) to clarify the critical size of the anterior defect and (2) to demonstrate the stabilizing mechanism of bone-grafting. METHODS Thirteen(More)
Seventy-eight Neer hemiarthroplasties and thirty-six Neer total shoulder arthroplasties were performed in patients aged 50 years or younger between January 1, 1976, and December 31, 1985. Sixty-two hemiarthroplasties and twenty-nine total shoulder arthroplasties with complete preoperative evaluation, operative records, and a minimum 15-year follow-up (mean,(More)
BACKGROUND We found no information in the literature regarding the relationship between patient and physician-derived outcome assessments with a shoulder questionnaire. In this study, we examined a group of patients who were assessed with patient and physician-administered questionnaires following shoulder arthroplasty. METHODS From August 2003 to(More)
Forty-eight shoulders that underwent glenoid component revision surgery were reviewed at a mean of 4.9 years (range, 2 to 12 years). The indications for surgery were glenoid component loosening in 29 shoulders, glenoid implant failure in 14 shoulders, and glenoid component malposition or wear leading to instability in 5 shoulders. Seventeen shoulders had(More)
Significant discrepancy in the functional outcome of hemiarthroplasty for proximal humerus fractures has been reported with short or mid-term follow-up. This study reports the long-term results and rate of complications of shoulder arthroplasty in the treatment of proximal humerus fractures. The review comprised 57 patients (44 women, 13 men) who underwent(More)
