Eighty-six reverse shoulder arthroplasty (RSA) cases performed through a deltopectoral (DP) approach were reviewed at an average of 17.2 months after surgery. All procedures were performed by 2 fellowship-trained shoulder surgeons who perform a high volume of shoulder arthroplasty. We describe the surgical technique for the DP approach for primary and revision RSA, preliminary results, intraope...

BACKGROUND AND PURPOSE Glenoid reconstruction and inverted glenoid re-implantation is strongly advocated in revisions of failed reverse shoulder arthroplasty (RSA). Nevertheless, severe glenoid deficiency may preclude glenoid reconstruction and may dictate less favorable solutions, such as conversion to hemiarthropasty or resection arthropasty. The CAD/CAM shoulder (Stanmore Implants, Elstree, ...

AIM To evaluate whether implant design, glenoid positioning, and other factors influenced instability and scapular notching in reverse total shoulder arthroplasty. METHODS We retrospectively reviewed records of patients who had undergone reverse total shoulder arthroplasty by the senior author from July 2004 through October 2011 and who had at least 24 mo of follow-up. The 58 patients who met...

Reverse shoulder arthroplasty may be performed using components that medialize or lateralize the center of rotation. The purpose of this prospective study was to directly compare 2 reverse shoulder arthroplasty designs. Two treatment groups and 1 control group were identified. Group I comprised 9 patients using a medialized Grammont-style (GRM) prosthesis with a neck-shaft angle of 155°. Group ...

BACKGROUND The number of total shoulder arthroplasties has increased exponentially over the last ten years, creating a more prominent role for revision shoulder arthroplasty in the future. The main reasons for failure of shoulder arthroplasty can be classified as soft-tissue deficiencies, osseous deficiencies, component wear, or infection. We hypothesized that, despite appropriate surgical tech...

BACKGROUND The presence of multiple allergies has been correlated with worse outcomes for patients undergoing hip and knee arthroplasty, but the effect of allergies has not yet been elucidated with respect to shoulder arthroplasty. PURPOSE/HYPOTHESIS The purpose of this study is to identify any discrepancies in shoulder arthroplasty outcomes with respect to reported drug allergies. We hypothe...

OBJECTIVE To assess results of CTA(®) partial shoulder arthroplasty for treatment of degenerative arthropathy of the rotator cuff. METHODS Between December 2006 and June 2009, 23 shoulders of 23 patients were submitted to CTA(®) type partial shoulder arthroplasty for treatment of arthropathy secondary to rotator cuff injury. Post-operative follow up time ranged from 6 to 35 months. Mean age w...

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 Arthroscopic glenohumeral debridement for symptom control has shown promising short term results in the young active population, when arthroplasty may not be a practical option due to the recommended activity restrictions, potential for complications and/or early wear, and a need for revision. The purpose of this study was twofold: 1) to examine the impact of arthroscopic debridement...
