Self-assessed outcome at two to four years after shoulder hemiarthroplasty with concentric glenoid reaming.

Background: Active and young individuals with glenohumeral arthritis who are treated with total glenohumeral arthroplasty are at risk for loosening or wear of the prosthetic glenoid component. This study tests the hypothesis that patients with severe glenohumeral arthritis have improvement in self-assessed shoulder comfort and function at two to four years after treatment with the combination of humeral hemiarthroplasty and concentric glenoid reaming without tissue or prosthetic component interposition.

Methods: Thirty-seven consecutive patients (thirty-eight shoulders), with a mean age of fifty-seven years, who were managed by one surgeon were enrolled in this prospective study.

The complex characteristics of 282 unsatisfactory shoulder arthroplasties.

The purpose of our study is to augment the knowledge of patient dissatisfaction after a shoulder arthroplasty. A total of 353 shoulders were prospectively enrolled into the Shoulder Arthroplasty Failure Experience (SAFE) project. Of these, 282 patients had complete data for the final analysis, including demographic information, medical history, physical examination, standard radiographs, and the Simple Shoulder Test (SST) scores.

Nonprosthetic glenoid arthroplasty with humeral hemiarthroplasty and total shoulder arthroplasty yield similar self-assessed outcomes in the management of comparable patients with glenohumeral arthritis.

The risk of glenoid component failure has led us to explore nonprosthetic glenoid arthroplasty coupled with humeral hemiarthroplasty, the "ream and run" (R&R) procedure, for the management of glenohumeral arthritis in active patients. We hypothesized that patients having a R&R procedure would have outcomes comparable with those of similar patients having a total shoulder arthroplasty (TSA). A case-matched control study compared 35 consecutive patients (32 men, 3 women) with an average age of 56 years, after R&R with matched controls having TSA.

Arthroscopic compared with open repairs for recurrent anterior shoulder instability. A systematic review and meta-analysis of the literature.

Background: Both arthroscopic and open surgical repairs are utilized for the management of anterior glenohumeral instability. To determine the evidence supporting the relative effectiveness of these two approaches, we conducted a rigorous and comprehensive analysis of all reports comparing arthroscopic and open repairs.

Methods: A systematic analysis of eighteen published or presented studies was performed to determine if there were significant differences between the two approaches with regard to recurrence (recurrent dislocation, subluxation, and/or apprehension and/or a reoperation for instability), return to work and/or sports, and Rowe scores.
