BACKGROUND Patients undergoing shoulder surgery in the beach chair position may be at increased risk for serious neurocognitive complications due to cerebral ischemia. We sought to define the incidence, patient risk factors, and clinical sequelae of intraoperative cerebral desaturation events. METHODS Regional cerebral tissue oxygen saturation (rSO2) was(More)
BACKGROUND Patients undergoing arthroscopic shoulder surgery in the beach chair position may be at increased risk for serious neurocognitive complications as a result of cerebral ischemia. QUESTIONS/PURPOSES We sought to define the (1) incidence; (2) timing; and (3) magnitude of intraoperative cerebral desaturation events (CDEs) in subjects undergoing(More)
BACKGROUND Heterotopic ossification is the most common extrinsic cause of elbow contracture and may lead to clinically important stiffness, and rarely, complete bony ankylosis. Surgery sometimes is performed to treat this problem, and published reports differ regarding the factors that are associated with success or failure after this operation and whether(More)
INTRODUCTION It has been previously demonstrated that medical students do not achieve an adequate musculoskeletal knowledge base on graduation from American medical schools. Several curriculums have been developed to address this measured deficit. Students entering orthopedic surgery residencies have a better musculoskeletal knowledge foundation than their(More)
BACKGROUND The Accreditation Council for Graduate Medical Education (ACGME) Resident Case Log System is designed to be a reflection of residents' operative volume and an objective measure of their surgical experience. All operative procedures and manipulations in the operating room, Emergency Department, and outpatient clinic are to be logged into the(More)
The aim of this prospective cohort study was to investigate the effect of head and neck positioning on cerebral perfusion during shoulder arthroscopy in the beach chair position. Regional cerebral tissue oxygen saturation (rSO2) was monitored intraoperatively using near-infrared spectroscopy on 51 consecutive patients undergoing arthroscopic shoulder(More)
Arthroscopic shoulder surgery with the patient in the beach-chair position (BCP) has been associated with neurocognitive complications caused by cerebral ischemia. We reviewed the current literature for the incidence of postoperative neurocognitive deficits, number of reported neurocognitive complications, and incidence of intraoperative cerebral(More)
BACKGROUND Glenoid retroversion may accelerate glenoid loosening after total shoulder arthroplasty. Accurate measurement of preoperative glenoid deformity is critical for decision-making and prognostication. The purpose of this study was to determine whether glenoid version, inclination, and depth and humeral subluxation measurements on computed tomography(More)
BACKGROUND Catheter-delivered continuous interscaleneanesthesia has demonstrated improved pain control in randomized clinical trials.The purpose of this study is to determine whether the introduction of continuous catheteranesthesia was associated with a change in length of stay (LOS), readmission, rates of discharge home without home health or nursing(More)
BACKGROUND Computed tomography (CT) scans are often obtained before total shoulder arthroplasty to assess glenoid deformity. To allow correction of the slice axis into the plane of the scapula, these scans have typically required inclusion of the entirety of the scapula. The purpose of this study was to determine whether inclusion of the medial border and(More)
