Complication rates following reverse and anatomic shoulder replacement in treatment of glenohumeral arthritis: a 10-year Medicare review study.

Background: We sought to compare the complication rates after anatomic total shoulder arthroplasty (aTSA) and reverse shoulder arthroplasty (RSA) for primary glenohumeral arthritis in a Medicare population.

Methods: Patients who underwent a shoulder arthroplasty were identified from the 5% subset of Medicare parts A/B between 2009 and 2019. Patients with less than 1-year follow-up were excluded.

Massive rotator cuff tears without arthropathy: when to consider reverse shoulder arthroplasty.

Massive rotator cuff tears often present a challenge for the treating orthopaedic surgeon. A multitude of surgical approaches have been described to manage this condition, ranging from biceps tenotomy to complex muscle transfers to reverse shoulder arthroplasty. Among these procedures, reverse shoulder arthroplasty is increasingly advocated to relieve pain and restore function; however, the exact role of this arthroplasty procedure continues to be defined, particularly in patients without any evidence of associated glenohumeral arthritis.

Reverse Shoulder Arthroplasty in the Management of Irreparable Rotator Cuff Tears without Arthritis.

Introduction: The ability to provide reliable outcomes in treatment of patients with degenerative rotator cuff tears has become increasingly complicated, as a result of more advanced disease and the increased array of treatment choices.

Step 1 Preoperative Planning: Develop and communicate with a consistent team of interdisciplinary physicians both preoperatively and postoperatively; utilize advanced imaging modalities to evaluate muscle atrophy as well as glenoid and humeral bone stock.

Step 2 Patient Positioning: Place the patient in a beach-chair position, check the abdominal strap, and position yourself facing the axilla.

Lunate-lunate facet ratio and variance to predict articular gap after distal radius fracture.

Purpose: Intra-articular gap is a well-defined prognosticator of outcome after distal radius fracture. However, it is often difficult to assess on plain radiographs, particularly in the sagittal plane, as visualized on the lateral view. The purposes of this study were to establish normal values for the lunate-lunate facet ratio (LLFR) and to evaluate whether the LLFR and lunate-lunate facet variance (LLFV) are reliable plain film measures of sagittal articular gap in distal radius fractures compared with sagittal reconstructions of computed tomography (CT) scans.

Small-diameter percutaneous decompression for osteonecrosis of the shoulder.

Core decompression of the humeral head has previously been used as a joint-preserving procedure for treatment of symptomatic osteonecrosis of the shoulder. In this article, we describe a new decompression technique, which involves multiple small-diameter (3-mm) percutaneous perforations. In our study population (early-stage disease), shoulder arthroplasty was avoided in all 15 patients (26 shoulders) for a mean follow-up of 32 months (range, 24-41 months).

Osteonecrosis of the humeral head.

Osteonecrosis of the humeral head is considerably less common than osteonecrosis of the hip. However, as in the hip, the interaction between a genetic predisposition and certain risk factors may lead to increased intraosseous pressure, loss of circulation, and eventual bone death. The most common risk factor remains corticosteroid use, which accounts for most reported cases.
