As surgeons learn to perform minimally invasive hip arthroplasty procedures, the various techniques will evolve and one or two approaches may eventually become the standard. Currently, most of these procedures are reserved for the nonmorbidly obese patients; however, as techniques are perfected and surgeons gain experience, this patient population may(More)
A temporary articulating antibiotic-impregnated cement spacer for use during the first stage of a two-stage revision of a total knee replacement that had failed because of infection was developed by one of us (W.M.G.). It is simply a knee prosthesis made of methylmethacrylate and antibiotics that is manufactured intraoperatively with use of instruments,(More)
A 72-year-old acyanotic woman had development of acute right heart failure with systemic hypotension 2 hours after a curative right intrapericardial pneumonectomy for primary lung cancer. A postoperative pulmonary angiogram revealed a major left to right shunt through previously unsuspected partial anomalous venous drainage of the left upper lobe of the(More)
Patella resurfacing in total knee arthroplasty (TKA) reduces postoperative complications and revisions; however, the optimal cutting depth and angle that minimize patellar strain and fracture remain unclear. We performed three-dimensional finite element analysis (FEA) of resurfacing cutting depth and obliquity to assess the stresses in each component of the(More)
The purpose of the present study is to determine whether the anconeus muscle contracts during abduction of the ulna. Abduction of the ulna occurs when pronation takes place around an axis passing through the head of the radius and the second digit. This is in contrast to pronation around an axis passing through the fifth digit, in which the ulna remains(More)
In serum and sputum samples from 15 patients with cystic fibrosis (CF) suffering from chronic Pseudomonas aeruginosa lung infections, concentrations and/or activities of elastase derived from polymorphonuclear leukocytes (PMN), cathepsin G, myeloperoxidase (MPO), and superoxide dismutase (SOD), as well as concentrations of the proteinase inhibitors alpha(More)
The goal of this study was to determine if obesity is a risk factor for total joint arthroplasty. This was a retrospective review of 130 patients treated with either primary total hip arthroplasty or primary total knee arthroplasty during a two-year period (154 consecutive arthroplasties). The patients were placed in the nonobese or obese group. Obesity was(More)
Ischemic contracture of the left ventricle ("stone heart") is a recognized complication of prolonged periods of interruption of the coronary circulation during open-heart surgery. We have examined the effects of moderate hypothermia (28 degrees C.) and preoperative beta-adrenergic blockade (propranolol, 0.5 mg. per kilogram; 1.0 mg. per kilogram) on(More)
This retrospective study evaluated the midterm clinical and radiographic outcomes of a second-generation total knee replacement system. In a multicentre consecutive series of 1512 patients, 1970 knees were treated with the PFC Sigma knee system (Depuy, Warsaw, Indiana). The patients were reviewed for functional outcome, and underwent independent(More)
