A comparative analysis of anatomic total shoulder arthroplasty versus reverse shoulder arthroplasty for posterior glenoid wear patterns.

Introduction: Reverse shoulder arthroplasty (RSA) and anatomic total shoulder arthroplasty (TSA) are well-known methods of treating glenohumeral arthritis, which often leads to posterior wear of the glenoid. This study compared minimum two-year outcome measures in patients treated with RSA and TSA for Walch B2 and B3 glenoids.

Methods: Thirty-eight shoulders underwent TSA and 40 shoulders underwent RSA by two fellowship-trained shoulder surgeons at a tertiary referral center.

The Role of Computed Tomography and Magnetic Resonance Imaging in the Diagnosis of Pediatric Thoracolumbar Compression Fractures.

Background: Because of concerns about radiation exposure, some centers consider magnetic resonance imaging (MRIs) the preferred imaging modality for pediatric thoracic and/or lumbar compression fractures. The purpose of this study was to evaluate the sensitivity of computed tomography (CT) and MRI in diagnosing thoracolumbar compression fractures and the utility of MRI in their management.

Methods: Retrospective review identified 52 patients aged 0 to 18 years with 191 thoracic and/or lumbar compression fractures who had both CT and MRI during the initial trauma evaluation.
