A painful condition known as snapping hip may prevent athletes from attaining peak performance, and it presents diagnostic and treatment challenges to the sports medicine physician as well. Three types of snapping hip (external, internal, and intra-articular) are known, and each has a distinct pathomechanic cause, specific symptoms, and classic clinical(More)
PURPOSE To retrospectively assess magnetic resonance (MR) imaging features of radial tunnel syndrome. MATERIALS AND METHODS Institutional review board approval was obtained, and informed consent was waived for the retrospective HIPAA-compliant study. MR images of 10 asymptomatic volunteers (six men, four women; mean age, 30 years) and 25 patients (11 men,(More)
To assess the ability of 3D MR shoulder reconstructions to accurately quantify glenoid bone loss in the clinical setting using findings at the time of arthroscopy as the gold standard. Retrospective review of patients with MR shoulder studies that included 3D MR reconstructions (3D MR) produced using an axial Dixon 3D-T1W-FLASH sequence at our institution(More)
Twenty-nine cases of operative arthroscopy of the ankle were done between 1985 and 1989 for synovial impingement of the ankle. The average age of the patients was 37 years. All patients (17 men, 12 women) reported an earlier history of injury, with 24 of the patients (83%) noting chronic ankle pain after an inversion injury and 5 of the patients (17%)(More)
Platelet-rich plasma is defined as autologous blood with a concentration of platelets above baseline values. Platelet-rich plasma has been used in maxillofacial and plastic surgery since the 1990s; its use in sports medicine is growing given its potential to enhance muscle and tendon healing. In vitro studies suggest that growth factors released by(More)
Tibial fixation of soft-tissue grafts is a weak link in anterior cruciate ligament reconstruction. Previous studies have examined varying interference screw lengths, screw types and tunnel sizes as means to improve graft fixation. We hypothesized that increasing interference screw diameter would significantly increase the maximum load to failure of the(More)
BACKGROUND To date, repair of the lacertus in distal biceps tendon ruptures, recommended by some, has not been evaluated. The goal of these biomechanical experiments was to evaluate the degree to which its repair increases the strength of a distal biceps tendon repair. HYPOTHESIS An intact or repaired lacertus fibrosus will increase the strength of a(More)
The acceptance and rates of hip arthroscopy are increasing in the United States and abroad and the literature describing it is expanding. Indications for hip arthroscopy include labral tears, loose bodies, femoroacetabular impingement, ruptured ligamentum teres, chondral injuries, adhesive capsulitis, instability, synovial disease, disorders of the(More)
OBJECTIVE This study aimed at identifying the optimal threshold value to detect cartilage lesions with Standardized delayed Gadolinium-Enhanced MRI of Cartilage (dGEMRIC) at 3 T and evaluate intra- and inter-observer repeatability. DESIGN We retrospectively reviewed 20 hips in 20 patients. dGEMRIC maps were acquired at 3 T along radial imaging planes of(More)
