Biomechanical similarities among subscapularis repairs after shoulder arthroplasty.
HYPOTHESIS Many authors suggest that subscapularis deficiency after shoulder arthroplasty has a negative effect on long-term outcomes. Thus, increasing emphasis has been placed on the technique for repair of the tendon. This study evaluated the biomechanical strength of 3 different repairs: osteotomy, tendon to bone, and a combined method. MATERIALS AND METHODS Twenty-four paired shoulders fr...
متن کاملEffect of lesser tuberosity osteotomy size and repair construct during total shoulder arthroplasty.
BACKGROUND Lesser tuberosity osteotomy has been shown to decrease postoperative subscapularis dysfunction. The purpose of this study was to determine the effect of osteotomy thickness and suture configuration on repair integrity. MATERIALS AND METHODS One side of 12 matched-pair cadaveric shoulders was randomly assigned to either a thick osteotomy (100% of lesser tuberosity height) or a thin ...
متن کاملReverse shoulder prosthesis for acute four-part fracture: tuberosity fixation using a horseshoe graft.
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...
متن کاملCharacteristics of Rotator Cuff Repairs Revised to Shoulder Arthroplasty
Background: Successful repair of a torn rotator cuff may prevent progression to rotator cuff arthropathy. However,previous studies have shown a substantial rate of failure after rotator cuff repair and characteristics of surgicallyrepaired rotator cuffs that go on to shoulder arthroplasty have not been fully elucidated. The purpose of this study wasto determine the patient cha...
متن کاملEarly Versus Late Reverse Shoulder Arthroplasty for Proximal Humerus Fractures: Does It Matter?
Background: This study compared the outcomes between patients with proximal humerus fractures (PHF) whounderwent acute reverse total shoulder arthroplasty (RSA) to those who underwent an alternative initial treatmentbefore requiring (secondary) RSA.Methods: Patients who underwent RSA after suffering a PHF were identified. Two year clinical follow-up was requiredfor inclusion. Patients were divi...
