PURPOSE The purpose of this study was to investigate intra-articular hip joint pathologies in professional athletes who sustained dislocation and were treated with hip arthroscopy. METHODS Between August 23, 2000, and September 15, 2006, 14 professional athletes (12 male and 2 female) sustained a nonfracture traumatic hip dislocation during active(More)
PURPOSE The purpose of this study was to quantify the change in degrees in the center-edge (CE) angle for each millimeter of acetabular rim resected in hips undergoing arthroscopic acetabular rim trimming. METHODS Preoperative and postoperative CE angle and millimeters of rim reduction were prospectively collected in 58 hips that underwent arthroscopic(More)
Topographic mapping of the cerebral cortex of 79 deaf children and a group of matched hearing children was performed, using measures of electroencephalographic coherence, phase, and power. Deaf children manifested higher coherence and lower phase in certain left hemispheric areas, suggesting less neural differentiation; but lower coherence and higher phase(More)
At our institution, fast spin-echo (FSE) proton density (PD) imaging is used to evaluate articular cartilage, while conventional spin-echo (CSE) T1-weighted sequences have been traditionally used to characterize meniscal pathology. We sought to determine if FSE PD-weighted sequences are equivalent to CSE T1-weighted sequences in the detection of meniscal(More)
Subacromial decompression and debridement of partial-thickness bursal-sided rotator cuff tears are often reported with a high rate of unsatisfactory outcomes. We describe an arthroscopic procedure to repair partial-thickness bursal-sided rotator cuff tears without converting to a full-thickness tear in patients with a normal articular-sided rotator cuff and(More)
Stem cells are defined by their unique capacity for self-renewal and multilineage differentiation. Stem cells have been obtained from multiple extramedullary tissues. Recently, a population of progenitor cells have been identified in the endometrium. However, multilineage differentiation of endometrial stem cells has not been reported. Endometrial tissue(More)
Partial-thickness rotator cuff tears are not a single entity; rather, they represent a spectrum of disease states. Although often asymptomatic, they can be significantly disabling. Overhead throwing athletes with partial-thickness rotator cuff tears differ with respect to etiology, goals, and treatment from older, nonathlete patients with degenerative(More)
Adequate control of movement is essential for patients to return to unrestricted function after hip arthroscopic surgery. Mobility, muscle performance and stability, and neuromuscular control are vital aspects addressed in rehabilitation to help re-establish control of movement for function. Initial joint protection is a hallmark for all patients after hip(More)
As the field of hip arthroscopy continues to grow rapidly, our understanding of the population of patients undergoing hip arthroscopy has led to improved diagnosis and management of hip joint pathologies. The Multicenter Arthroscopic Study of the Hip (MASH) Study Group conducts multicenter clinical studies in arthroscopic hip preservation surgery. Patients(More)
The intracarotid amobarbital procedure (IAP) was conducted with a profoundly deaf young man prior to right anteromedial temporal lobectomy for pharmacologically refractory partial complex seizures. The IAP required considerable modification in order to take into account the use of varying sign language methods and related issues. Visual memory, American(More)
