PURPOSE The aim of this study was to prospectively test the hypothesis that 6-fold acceleration of a 3-dimensional (3D) turbo spin echo (TSE) magnetic resonance imaging (MRI) pulse sequence with k-space undersampling and iterative reconstruction is feasible for fast high spatial resolution MRI of the knee, while yielding similar image quality and diagnostic(More)
We analyzed the tumor-related questions on the Orthopaedic In-Training Examinations (OITE) over a 5-year period (2002-2006). Each year approximately 27 of the 275 examination questions (10%) are tumor-related. Malignant conditions are tested more than benign ones (1.2:1). Approximately nine questions per year are immediate recall of specific entities, while(More)
Biceps tenodesis provides reliable pain relief for patients with biceps tendon abnormality. Previous cadaver studies have shown that, for biceps tenodesis, an interference screw provides biomechanical strength to failure superior to that of suture anchors. This finding has led some providers to conclude that screw fixation for biceps tenodesis is superior(More)
Slipped capital femoral epiphysis is a relatively common disorder in late childhood and early adolescence, with an incidence in the United States of approximately 10 per 100,000. Although clinicians have theorized that contributing factors to the development of slipped capital femoral epiphysis include 25-hydroxyvitamin D deficiency and other nutritional(More)
BACKGROUND Pediatric orthopedics has been a frequently tested topic on the Orthopaedic In-Training Examination (OITE). Our goal was to provide direction for resident education efforts by: (1) analyzing the exam's number, topics, and types of pediatric orthopedic surgery questions; (2) examining references cited in the postexam answer packet supplied by the(More)
The advent of arthroscopy and the scientific study of the efficacy and accuracy of that examination have led to important advances in our understanding of the shoulder examination in the overhead and throwing athlete. In this review, we address current physical examination techniques and how to perform them, and explore their reported clinical efficacy,(More)
Isokinetic concentric quadriceps and hamstring strength data using a Cybex dynamometer are collected for elite collegiate American football players invited to the annual National Football League Scouting Combine. We constructed a normative (reference) database of the Cybex strength data for the purpose of allowing comparison of an individual's values to his(More)
The annual incidence of hip fractures in the United States is expected to double by the year 2050. An additional challenge is that comorbidities are common in elderly patients. As indications for implantation of cardiac rhythm devices continue to broaden, the number of elderly patients with a pacemaker or an implantable cardioverter-defibrillator seen in(More)
