The long-term complications related to the patella were retrospectively evaluated for 891 knees (684 patients) that had had a total arthroplasty, with or without resurfacing of the patella, with use of an unconstrained, condylar, posterior-cruciate-preserving prosthesis. The study population comprised two groups of patients who were similar in size, age,(More)
Five hundred twenty-eight pulmonary artery catheters were inserted in 500 patients at the New York University Medical Center between May and November, 1981. Complications occurred in 126 of 528 catheterizations. Serious complications occurred in only 23 of these 528 catheterizations (4.4 percent). These complications, while serious, did not contribute(More)
The results of total shoulder arthroplasty and hemiarthroplasty in a similar patient population were compared in an effort to define more clearly the indications for resurfacing the glenoid. The results of 64 Neer hemiarthroplasties in 59 patients were compared with 146 Neer total shoulder arthroplasties in 134 patients in a retrospective review of the(More)
A retrospective review of 131 Neer total shoulder arthroplasties in 111 patients performed between 1974 and 1986 was undertaken to identify factors associated with proximal humeral migration. The influence of proximal migration on results was evaluated to clarify the indications for prosthetic constraint. The average follow-up period was 55 months (range:(More)
In a review of records and radiographs from 1974 through 1988, we identified seven patients who had a humeral fracture after either a total shoulder replacement or a shoulder hemiarthroplasty. All seven patients had complications after the fracture, and five fractures did not unite until an operation was done. All of the fractures that were treated(More)
CT was compared to fiberoptic bronchoscopy in a large series of patients to study the value of CT for visualizing bronchial disease. CT scans were available for review in 64 cases in which focal airway disease was identified with fiberoptic bronchoscopy and in 38 patients in whom the airways appeared normal at bronchoscopy. CT was positive in 59 of 64 cases(More)
Spontaneous pneumothorax in patients with acquired immunodeficiency syndrome (AIDS) may require prolonged therapy for treatment of a persistent bronchopleural fistula, and treatment by standard methods often fails. This pilot study was done to test the effectiveness of aggressive surgical therapy for definitive treatment of persistent bronchopleural fistula(More)
