A study was undertaken in September 1988 of 169 patients who were > 50 years of age receiving care for hip fractures at 4 university-affiliated hospitals during a 2-year period. Demographics, medical history, cognitive function, mobility, and environmental factors surrounding the hip fractures were ascertained by patient or proxy interview and review of(More)
A dynamic weight-bearing model has been developed in a cadaveric ankle model to assess the contact areas of the talus in varying degrees of bimalleolar ankle fractures. A surgically created transverse fibula osteotomy with up to 6 mm of displacement did not cause a significant change in the contact area. Sectioning of the deltoid ligament, regardless of(More)
The aim of the uncemented femoral component in total hip arthroplasty is to achieve a stable bone-prosthesis interface without the use of polymethyl methacrylate (PMMA). Maximal fill of the femoral canal by the prosthesis promotes initial stability and long-term optimal stress transfer to the bone. The percentage "fit and fill" of the proximal femur by(More)
There is no clear consensus about the best operative technique for the treatment of digital mucous cysts. We carried out a retrospective review of all patients who underwent excision of a digital mucous cyst using a local advancement skin flap over a 10-year period. A total of 69 patients were included and were reviewed at an average of 38 months (minimum 6(More)
The stability of two commonly used uncemented acetabular prostheses fixed with either pegs or screws has been established by evaluating the torque strengths in ten cadaveric acetabulae. The initial stability of implants to simulated frictional loads was satisfactory compared to previous estimations of the frictional torques in polyethylene-on-metal and(More)
This study compares the strength and rigidity of four methods of internal fixation for arthrodesis of the first metatarsophalangeal joint. Ten matched pairs of cadaveric first rays were harvested and arthrodesis performed by one of four techniques: (1) planar excision of joint surfaces and fixation with crossed Kirschner wires, (2) planar excision of joint(More)
An intramedullary pin is commonly used for wrist arthrodesis in patients with rheumatoid arthritis. However, pin migration is a recognized complication of this technique. We report the results of wrist fusion in 15 patients using a modified technique with a transverse blocking screw inserted into the metacarpal distal to the intramedullary pin to prevent(More)
A case study was undertaken to determine perceptions about protective garments for the prevention of recurrent hip fractures. We studied 169 patients with hip fractures, over 50 years of age, who were admitted to four university-affiliated hospitals. Proxy respondents were interviewed for 36% (n = 61) of the patients. Significant differences were found in(More)
