Acute isolated rupture of the teres major is an uncommon injury. This article presents the first report of midterm subjective and objective functional results following nonoperative management of an isolated teres major rupture. A 30-year-old right hand dominant man presented after a waterskiing traction injury to his left upper extremity. ⋯ At 3-year follow-up, the patient had no subjective complaints in the injured extremity and excellent functional outcome scores. A mean 37 kg loss of internal rotation strength (as measured by dynamometer) in the affected extremity with the arm abducted to 90° existed, although this difference was not subjectively appreciable. Although previously published reports have presented various options for the management of teres major injuries, the present case demonstrates that nonoperative treatment can produce excellent midterm subjective results in spite of objective internal rotation weakness.

Athletes with superior labral tear from anterior to posterior (SLAP) lesions place large demands on their rotator cuff and often have partial articular-sided rotator cuff tears as part of an internal impingement process. A percutaneous technique that facilitates SLAP repair may decrease the rotator cuff morbidity associated with establishment of the standard Wilmington portal. The current study reports the clinical outcome of patients with SLAP lesions treated with a percutaneous repair technique. ⋯ There was no significant difference in functional scores between Type II lesions versus combined lesions, or between patients with or without a concurrent low-grade rotator cuff tear. Ninety percent of athletes were able to return to sport at pre-injury level of function. Percutaneously-assisted arthroscopic SLAP lesion repair may minimize surgical morbidity to the rotator cuff and provides excellent results.

The goal of this study was to determine the efficacy and feasibility of surgical management of advanced thoracolumbar spine tuberculosis with kyphosis in children in poor general condition with 1-stage posterior decompression, interbody grafts, and posterior instrumentation and fusion. Between 2006 and 2008, 7 children with advanced thoracolumbar spinal tuberculosis accompanied by kyphosis and in poor general condition were treated with 1-stage posterior decompression, interbody grafts, and posterior instrumentation and fusion followed by chemotherapy. Mean follow-up was 34 months (range, 27-42 months). ⋯ Average preoperative kyphosis was 37.9°, which decreased to 5.4° postoperatively. There was no significant loss of correction at last follow-up. Our results show that 1-stage posterior decompression, interbody grafts, and posterior instrumentation and fusion followed by chemotherapy is an alternative treatment for children with advanced thoracolumbar spinal tuberculosis and in poor general condition.

The objective of this investigation was to evaluate the reliability of classification systems by determining inter- and intraobserver agreement in displaced distal radius fractures. Radiographs of 32 patients (21 men and 11 women with a mean age of 41.6 years) who presented with a displaced distal radius fracture were classified by 9 orthopedic surgeons (5-25 years experience) using 5 different classification systems (Fernandez, AO, Frykman, Melone, and Universal Classification systems) twice with 20-day intervals. The results were processed with kappa statistics and used in assessment of inter- and intraobserver agreement of the classification systems. ⋯ Fernandez classification system had the highest interobserver agreement (0.235) and Melone classification system had the lowest interobserver agreement (0.056). According to the results of our study, the systems used to classify the displaced distal radial fractures are insufficient. A new classification system that ensures the 3-dimensional assessment of the fracture is more user-friendly and a high inter- and intraobserver agreement is necessary.

Tumor-induced or oncogenic osteomalacia is a rare paraneoplastic syndrome characterized by overproduction of fibroblast growth factor-23 as a phosphaturic agent and renal phosphate wasting. A range of predominantly mesenchymal neoplasms have been associated with tumor-induced osteomalacia and classified as phosphaturic mesenchymal tumor mixed connective tissues. However, phosphaturic mesenchymal tumor mixed connective tissues could be nonphosphaturic in the first stage of the disease, either because the tumors are resected early in the clinical course or because the patient's osteomalacia was attributed to another cause. ⋯ A lumbopelvic corset was applied for 3 months. At 12 months, the patient was asymptomatic. Serum and urine values of calcium and phosphorous were normal throughout the follow-up evaluation.
