BACKGROUND Controversy persists regarding the ideal surgical technique for repair of a ruptured Achilles tendon. We propose a limited open procedure with use of an instrument that provides the advantage of an open repair but avoids the soft-tissue problems with which open repair has been associated. METHODS We first performed a cadaver study in order to(More)
BACKGROUND Surgery is frequently considered an option for refractory, symptomatic noninsertional Achilles tendinopathy. Gastrocnemius equinus can result in mechanical overload of the Achilles tendon and may be a factor in its etiology. Our hypothesis was that reducing load transmission to the Achilles tendon by gastrocnemius lengthening (Strayer procedure)(More)
BACKGROUND Comparisons of different staphylococci in orthopedic implant infections have rarely been reported. In this study we assessed total joint arthroplasty infections and other orthopedic implant infections due to methicillin-sensitive Staphylococcus aureus (MSSA), methicillin-resistant Staphylococcus aureus (MRSA), and coagulase-negative staphylococci(More)
OBJECTIVES No evidence-based recommendations exist for the management of infectious bursitis. We examined epidemiology and risk factors for recurrence of septic bursitis. Specifically, we compared outcome in patients receiving bursectomy plus short-course adjuvant antibiotic therapy (<or=7 days) with that of patients receiving bursectomy plus longer-course(More)
BACKGROUND The failure of nonsurgical treatment of patients with midfoot and hindfoot deformity secondary to diabetic Charcot arthropathy may lead to a rocker-bottom foot deformity with recurrent or persistent plantar ulceration. We report our experience with realignment and extended fusion with primary use of a medial column screw for this midfoot(More)
We hypothesized an association between foot type, foot deformity, and foot ulceration and conducted an analysis of a well-characterized, high-risk diabetic population of 398 subjects. The average age was 62 years of age and 74% of the study population were males. Foot-type distributions were 19.5% pes cavus (high arch), 51.5% neutrally aligned (normal(More)
Dislocation of the peroneal tendons associated with calcaneus fractures should be repaired during fracture fixation to prevent complications. The only documented approach for repair is by proximal extension of the vertical limb of the lateral extensile approach to the calcaneus. However, enlarging the inherently fragile calcaneus flap places it at further(More)
BACKGROUND Second-generation total ankle arthroplasty has been reported to have good intermediate-term results. The purpose of the present study was to report on the cause and frequency of reoperation and failure after total ankle arthroplasty and to determine demographic and clinical predictors of reoperation and failure. METHODS Three hundred and six(More)
The most commonly used therapy for prosthetic joint infection is a two-stage prosthetic exchange separated by 6 weeks of intravenous antibiotic therapy. This often results in long periods of hospitalization, morbidity, severe functional impairment and sometimes increased mortality. Therefore novel and challenging therapeutic approaches have been attempted,(More)
Long-term studies evaluating risk factors for development of ankle osteoarthritis (OA) following malleolar fractures are sparse. We conducted a retrospective cohort study including consecutive patients treated by open reduction and internal fixation for malleolar fracture between January 1988 and December 1997. Perioperative information was obtained(More)
