Evaluation of the first-generation AAOS clinical guidelines on the prophylaxis of venous thromboembolic events in patients undergoing total joint arthroplasty: experience with 3289 patients from a single institution.
Patients undergoing total hip or total knee arthroplasty have risks that include venous thromboembolism. The American Academy of Orthopaedic Surgeons has promulgated guidelines for the preoperative assessment of patients with the primary objective of preventing pulmonary embolism. We aimed to evaluate and establish the utility of the first-generation American Academy of Orthopaedic Surgeons guidelines for the prophylaxis of venous thromboembolism in patients undergoing total joint arthroplasty at a single institution. ⋯ Therapeutic Level IV.

Prevalence of rotator cuff tears in adults with traumatic brachial plexus injuries.
Restoration of shoulder function is a primary goal when treating patients with traumatic brachial plexus injury. A concomitant rotator cuff tear may alter the treatment approach and prognosis for these individuals. The purpose of this study was to define the prevalence of rotator cuff tears in patients with traumatic brachial plexus injuries. ⋯ Prognostic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Multicenter StudyThe effect of surgeon experience on outcomes of surgery for adolescent idiopathic scoliosis.
Single-surgeon series investigating the learning curve involved in surgery for spinal deformity may be confounded by changes in technology and techniques. Our objective with this multicenter, prospective study was to present a cross-sectional analysis of the impact of surgeon experience on surgery for adolescent idiopathic scoliosis. ⋯ Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Randomized Controlled Trial Comparative StudyComparison of two percutaneous volar approaches for screw fixation of scaphoid waist fractures: radiographic and biomechanical study of an osteotomy-simulated model.
When a surgeon uses a percutaneous volar approach to treat scaphoid waist fractures, central screw placement is complicated by the shape of the scaphoid and by obstruction by the trapezium. In this study, we used radiographs and biomechanical tests to compare the standard volar percutaneous approach with the transtrapezial approach, with regard to central screw placement at the distal pole of the scaphoid. ⋯ The data suggest that, in a cadaveric osteotomy-simulated scaphoid waist fracture model, the transtrapezial approach reliably achieves central positioning of a screw in the proximal and distal poles. This position offers a biomechanical advantage compared with central placement in only the proximal pole.
