In a large cohort of osteogenesis imperfecta type V (OI type V) patients (17 individuals from 12 families), we identified the same mutation in the 5' untranslated region (5'UTR) of the interferon-induced transmembrane protein 5 (IFITM5) gene by whole exome and Sanger sequencing (IFITM5 c.-14C > T) and provide a detailed description of their phenotype. This(More)
The biology of fracture healing is better understood than ever before, with advancements such as the locking screw leading to more predictable and less eventful osseous healing. However, at times one's intrinsic biological response, and even concurrent surgical stabilization, is inadequate. In hopes of facilitating osseous union, bone grafts, bone(More)
OBJECTIVE Golf is a widely popular sport in the United States with 29 million Americans participating in the game. With an aging population and increased incidence of glenohumeral degenerative arthritis, the number of active golfers requiring total shoulder replacement is on the rise. This study aims to evaluate the effect of total shoulder replacement on(More)
BACKGROUND CONTEXT The intervertebral disc primarily relies on trans-endplate diffusion for the uptake of nutrients and the clearance of byproducts. In degenerative discs, diffusion is often diminished by endplate sclerosis and reduced proteoglycan content. Mechanical loading-induced convection has the potential to augment diffusion and enhance net(More)
BACKGROUND Knee pain is one of the most common reasons for outpatient visits in the U.S. The great majority of such cases can be effectively evaluated through physical examination and judicious use of radiography. Despite this, an increasing number of magnetic resonance images (MRIs) of the knee are being ordered for patients with incomplete work-ups or for(More)
Chronic musculoskeletal pain results from a complex interplay of mechanical, biochemical, psychological, and social factors. Effective management is markedly different from that of acute musculoskeletal pain. Understanding the physiology of pain transmission, modulation, and perception is crucial for effective management. Pharmacologic and nonpharmacologic(More)
A 24-year-old military policeman underwent arthroscopic femoral neck osteoplasty and labral repair of his right hip following failed conservative management of femoroacetabular impingement. His postoperative course was complicated by recurring posterior instability of his right hip initially presenting as a posterior dislocation on postoperative day 19.(More)
OBJECTIVE Dedicated orthopaedic operating rooms (DOORs) are increasingly popular solutions to reducing after-hours procedures, physician fatigue, and elective schedule disruptions. Although the benefits to surgeons are well understood, there are comparatively few studies that explore the effects of DOORs on patient care. We compared treatments and outcomes(More)
