BACKGROUND We examined a large cohort of patients who had interdigital neurectomy and evaluated their clinical outcomes by using a previously developed scoring system as well as a visual analog scale (VAS). In addition, we wanted to identify risk factors that may lead to poorer outcomes. MATERIALS AND METHODS A retrospective review identified 232 patients(More)
Thromboembolic disease presents a potentially fatal complication to patients undergoing orthopaedic surgery. Although the incidence after hip and knee surgery has been studied and documented, its incidence after surgery of the foot and ankle is unknown. For this reason, a prospective multicenter study was undertaken to identify patients with clinically(More)
Since the advent of extracorporeal shock wave lithotripsy (ESWL) concern has surfaced as to the long-term risk of the development of hypertension, as well as risk to the developing kidney. To study this concern 8 infant and 3 adult rhesus monkeys (Macaca mulatta) underwent treatment with the XL1 experimental lithotriptor to 1 kidney varying the amount of(More)
In a group of 160 patients who had hindfoot fusions (isolated subtalar, talonavicular, and calcaneocuboid fusions and double and triple arthrodeses), smokers had a significantly higher rate of nonunion than did nonsmokers (18.6% vs. 7.1%). The relative risk of developing a nonunion was 2.7 times higher for smokers than non-smokers. With the numbers(More)
The purpose of this study was to evaluate the development of clinically significant avascular necrosis of the head of the first metatarsal after: (1) distal metatarsal osteotomy of the chevron configuration beginning apically at the center of the metatarsal head and extending into the head metatarsal neck junction and (2) release of the adductor hallucis(More)
The hallucal sesamoids, although small and seemingly insignificant, play an important role in the function of the great toe by absorbing weight-bearing pressure, reducing friction, and protecting tendons. However, the functional complexity and anatomic location of these small bones make them vulnerable to injury from shear and loading forces. Injury to the(More)
The purpose of this study was to define the amount of lateral displacement of the chevron osteotomy to obtain a 50% displacement of the capital fragment. While mathematical analyses exist to predict the degree of correction of the intermetartarsal 1-2 angle with a distal metatarsal osteotomy, no guidelines exist regarding the degree of displacement(More)
The sesamoids of the great toe, which are small and seemingly insignificant bones, can be the site of disabling pathology for the athlete. Sesamoiditis, osteochondritis, partite sesamoids with stress fractures, displaced fractures, and osteomyelitis have all been reported in the athlete. Bursitis beneath the tibial sesmoid and flexor hallucis brevis(More)
Ten cadaver specimens were used to study the effect of distal fibular resection and ligamentous repair on ankle laxity. The distal fibula was resected sequentially at three levels. Talar tilt and anterior drawer were measured on stress radiographs after resection and then after ligament repair. Sequential resection of the distal fibula caused a progressive(More)
