Background and purpose - The number of shoulder registries increases. We assessed international trends in use of shoulder arthroplasty, and described the current state of procedure selection and outcome presentation as documented in national and regional joint registries. Methods - Published reports from 9 population-based shoulder arthroplasty registries (country/region: Norway, Sweden, New Ze...

BACKGROUND The younger patient with glenohumeral arthritis presents a challenge because of concerns about activity and frequency of failure. The purpose of this study was to define the results, complications, and frequency of revision surgery in this group. MATERIALS AND METHODS Between 1986 and 2005, 46 total shoulder arthroplasties and 20 hemiarthroplasties were performed in 63 patients who...

Total shoulder arthroplasty is a common treatment for glenohumeral arthritis. One of the most common failure modes of total shoulder arthroplasty is glenoid loosening, causing postoperative pain, limitation of function, and potentially, the need for revision surgery. The literature has devoted considerable attention to the design of the glenoid component; efforts to better understand the biomec...

BACKGROUND Reverse total shoulder arthroplasty provides a surgical alternative to standard total shoulder arthroplasty for the treatment of selected complex shoulder problems. The purpose of the present study was to evaluate the effects of etiology on the results of reverse total shoulder arthroplasty. METHODS Between May 1995 and June 2003, 240 consecutive reverse total shoulder arthroplasti...

The authors report on their experience in revision total shoulder arthroplasty using the Delta III shoulder prosthesis, a reversed constrained prosthesis which is known to give good functional results in the rotator cuff-deficient shoulder. It was implanted in patients with a failed total or hemishoulder prosthesis. The Constant-Murley score was used to assess the functional outcome. The prelim...

Shoulder arthroplasty has been the subject of marked advances over the last few years. Modern implants provide a wide range of options, including resurfacing of the humeral head, anatomic hemiarthroplasty, total shoulder arthroplasty, reverse shoulder arthroplasty and trauma-specific implants for fractures and nonunions. Most humeral components achieve successful long-term fixation without bone...

BACKGROUND Revision in failed shoulder arthroplasty often requires removal of the humeral component with a significant risk of fracture and bone loss. Newer modular systems allow conversion from anatomic to reverse shoulder arthroplasty with retention of a well-fixed humeral stem. We report on a prospectively evaluated series of conversions from hemiarthroplasty to reverse shoulder arthroplasty...

BACKGROUND Revisions of apparently "aseptic" shoulder arthroplasties are not infrequently culture positive for Propionibacterium, organisms that may be introduced at the time of the index surgery when the dermal sebaceous glands are transected. This report seeks to answer the question, Do surgeons performing revision shoulder arthroplasty years after the index procedure need to be concerned abo...
