BACKGROUND With an increasingly large number of patients undergoing total shoulder arthroplasty (TSA) combined with increased requirements for public reporting of patient outcomes, there is a greater need to better understand the underlying factors related to patient satisfaction. The purpose of this study was to compare patient demographics, nonorthopedic comorbidities, patient-reported outcom...

BACKGROUND AND PURPOSE Anatomic total shoulder arthroplasty (TSA) gives good outcome in the treatment of primary osteoarthritis, but it is not known whether this also applies to patients over 80 years old. PATIENTS AND METHODS We retrospectively assessed outcome in patients over the age of 80 after anatomic TSA, performed for primary osteoarthritis with a preoperative intact rotator cuff (gro...

INTRODUCTION This study quantified bone removed to correct three different sizes of posterior glenoid defects and also quantified the change in rotator cuff muscle length resulting from correction of each defect using three different glenoid designs. METHODS A 3-D computer model quantified the cortical and cancellous bone removed when correcting three sizes of posterior glenoid defects and si...

BackgroundTreatment of primary osteoarthritis with glenoid dysplasia or Walch type C glenoids remains controversial. There is scant literature available on patient outcomes after anatomic shoulder arthroplasty in patients glenoids. The purpose this study was to evaluate the total (TSA) for dysplastic standard (nonaugmented) components compared TSA concentric wear and minimal erosion (Walch A1)....

Results of hemiarthroplasty for complex four-part proximal humerus fractures in the elderly have been unreliable. Although patients often achieve pain relief, return of above-shoulder level function can be challenging, because tuberosity nonunion, malunion, and/or resorption is quite common. The reverse shoulder replacement has been advocated as a reliable alternative for these patients. Prelim...

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...

Prosthetic shoulder arthroplasty is becoming increasingly popular. The most widely reported procedures are hemiarthroplasty and unconstrained total arthroplasty using the Neer II prosthesis, which involves insertion of a press-fit or cemented humeral component and a cemented polyethylene glenoid implant. Long-term studies show that excellent or good results are achieved in over 90% of cases, wi...
