Compared with smaller tears, massive rotator cuff tears present significant clinical management dilemmas for the treating surgeon because they are often fraught with structural failure and poor outcomes. To optimize healing, current surgical methods look to optimize footprint coverage and enhance the biological environment for healing. Double-row techniques(More)
BACKGROUND Total shoulder arthroplasty (TSA) results in superior clinical outcomes to hemiarthroplasty (HA); however, TSA is a more technical and invasive procedure. This study retrospectively compares perioperative complications after HA and TSA using the National Surgical Quality Improvement Program (NSQIP) database. METHODS The NSQIP user file was(More)
BACKGROUND Proximal femoral deformities and overcorrection of the acetabulum both can result in secondary femoroacetabular impingement and suboptimal clinical results after periacetabular osteotomy. The purpose of the present study was to determine the rate of complications, the need for reoperations, radiographic correction, and hip function among patients(More)
Proximal humerus fractures have rarely been associated with injuries to the axillary artery. Most of the fractures described have been Neer 2-part surgical neck fractures with medialization of the shaft fragment and resultant laceration or thrombosis of the axillary artery. No intraoperative deaths have been reported. We present a series of 3 proximal(More)
BACKGROUND Little data are available to prioritize quality improvement initiatives in shoulder surgery. PURPOSE To stratify the risk for 30-day postoperative morbidity in commonly performed surgical procedures about the shoulder completed in a hospital setting and to determine patient factors associated with major complications. STUDY DESIGN Cohort(More)
ATP-sensitive potassium (K(+)(ATP)) channels regulate cell excitability and are expressed in steroid-responsive brain regions involved in sexual behavior, such as the preoptic area (POA) and medial basal hypothalamus (MBH). We hypothesized that K(+)(ATP) channels serve as a mechanism by which testosterone can control the electrical activity of neurons and(More)
BACKGROUND The purpose of this study was to analyze a population of patients with bilateral reverse total shoulder arthroplasty (RTSA) to evaluate their ability to perform activities of daily living and personal hygiene tasks. METHODS At a minimum 2-year follow-up, we retrospectively reviewed 50 patients (100 shoulders) with a mean age of 72 years who(More)
OBJECTIVES This comparative effectiveness study sought to determine the impact of complications, readmission, and procedure choice on in-hospital and total 90-day costs for surgical management of proximal humerus fractures. METHODS Medicare claims data from the Upstate New York area (2008-2009) were evaluated. The study included all patients treated with(More)
Early-onset scoliosis is potentially fatal if left untreated. Although surgical management with growing instrumentation may be necessary, this is not a panacea and is associated with high complication rates. Recent evidence has demonstrated that nonsurgical treatment can be an effective early management strategy in delaying or even precluding the need for(More)
BACKGROUND This study analyzed workers' compensation patients after surgical or nonoperative treatment of clavicle fractures to identify factors that influence the time for return to work and total health care reimbursement claims. We hypothesized that return to work for operative patients would be faster. METHODS The International Classification of(More)
