We investigated the effects of implementation of an institution-wide screening and decolonization protocol on the rates of deep surgical site infections (SSIs) in patients undergoing primary knee and hip arthroplasties. 2058 patients were enrolled in this study: 1644 patients in the treatment group and 414 in the control group. The treatment group attended(More)
Fracture-dislocation of the elbow is a signiicant injury with mixed outcomes. The purpose of the study was to evaluate patient perceived outcome following surgical stabilization of these complex injuries. Twenty-nine available patients (76%) from 37 identiied with "terrible triad" injury patterns, in- cluding ulnohumeral dislocation, radial head fracture,(More)
BACKGROUND The impact of strict enforcement of Section 405 of the New York State Public Health Code to restrict resident work to eighty hours per week and the adoption of a similar policy by the Accreditation Council on Graduate Medical Education in 2002 for orthopaedic residency training have not been evaluated. Adoption of these rules has created(More)
In July 2003, the Accreditation Council for Graduate Medical Education (ACGME) established nationwide guidelines for resident working environments and duty hours. Following these guidelines became a requirement for all accredited residency programs. Two years after implementation, we conducted a national survey to assess the opinions and attitudes of(More)
UNLABELLED Tourniquet use is effective in producing a bloodless field. It is recommended that the least effective pressures be used to minimize tissue microstructure and biochemical damage from tourniquet application. When applied at the thigh, the minimum effective tourniquet pressure is 90 to 100 mm Hg above systolic BP, and in a normotensive, nonobese(More)
Understanding patients' perceived health status, as measured by health state utility, is important when evaluating the societal impact of hip osteoarthritis (OA) and total hip arthroplasty (THA). The purpose of this study was to measure health state utility in patients with hip OA and THA. A total of 231 patients from 2 institutions were enrolled into 1 of(More)
BACKGROUND Methicillin-resistant Staphylococcus aureus and methicillin-sensitive Staphylococcus aureus surgical site infections are an increasing health problem in the United States. To date, no study, as far as we know, has evaluated the prevalence of Staphylococcus aureus colonization in orthopaedic surgeons. The purpose of our study was to assess the(More)
BACKGROUND Non-invasive imaging techniques such as magnetic resonance imaging (MRI) provide the ability to evaluate the complex anatomy of bone and soft tissues of the wrist without the use of ionizing radiation. Dynamic instability of wrist--occurring during joint motion--is a complex condition that has assumed increased importance in musculoskeletal(More)
Over years of practice, many beliefs and practices become entrenched as tried and tested, and we subconsciously believe they are based on scientific evidence. We identified nine such beliefs by interviewing orthopaedic surgeons in which studies (or lack thereof) apparently do not support such practices. These are: changing the scalpel blade after the skin(More)
The objective of this study was to determine demographic characteristics and epidemiology of hand, wrist, and forearm fracture patients treated in the emergency departments (EDs) to identify the at-risk populations. The Nationwide Emergency Department Sample database collected by the Agency for Healthcare Research and Quality was used to estimate ED visits(More)
