INTRODUCTION: Loosening of glenoid components in total shoulder arthroplasty is a common clinical problem which can necessitate revision surgery. The mechanism of loosening is poorly understood and may be related to factors including implant design, component fixation techniques, and to tensile stresses at the interfaces. We are unaware of any studies that have examined the fundamental aspects ...
BACKGROUND The substantial increase in the utilization of shoulder arthroplasty in the United States during the past decade is partly attributable to the growing acceptance of reverse shoulder arthroplasty (RSA). This study compared the national utilization of and indications for shoulder hemiarthroplasty, total shoulder arthroplasty (TSA), and RSA. METHODS The Nationwide Inpatient Sample was...
BACKGROUND Cementless humeral resurfacing arthroplasty is a bone-conserving arthroplasty option for patients with glenohumeral arthritis. It has been successful in the older patient population. However, data regarding the results of arthroplasty in younger, more active patients are lacking. We report the two-year results of this procedure in active patients who were less than fifty-five years o...
Ceramic bearing surfaces are being increasingly used in young patients undergoing total hip arthroplasty. However,failures have been reported including fractures even with the newer third generation ceramics. The recommendedtreatment for fracture of ceramic bearing surfaces is complete synovectomy and revision total hip arthroplasty.However, disappointing results have also bee...
Infections of a total joint replacement (TJR) of the shoulder are rare complications. After revision surgery, the incidence rises dramatically. If infection occurs, it leads to a loss of function and may be devastating to the joint. Treatment options range from single- to multiple-staged revision programs, permanent resection arthroplasty or exarticulation. In this case, a reversed shoulder end...
There is limited information on activity levels of patients with reverse total shoulder arthroplasty (RTSA). We conducted a study of the types of sporting activities in which 78 patients with RTSA could participate. Mean follow-up was 4.8 years. Mean (SD) age at surgery was 75.3 (7.5) years. Seventy-five percent of the patients were women. Sixty-one percent underwent surgery for cuff tear arthr...
