We sought to determine the optimum surgical treatment of claw and hammer toes (except for the hallux) on the basis of the specific pathological anatomy of each type of deformity. We dissected thirty-three fresh-frozen specimens that had been obtained from below-the-knee amputations. The specimens included ten normal feet, fourteen feet that had claw toes,(More)
The ankle is stabilized by three sets of ligaments: the medial collateral (deltoid) ligament, the syndesmotic ligamentous complex, and the lateral collateral ligament. Of these three, the lateral collateral ligament is the one most often injured in ankle sprains. Assessment of the extent of injury has classically relied on clinical evaluation; plain film(More)
Sixty-one patients underwent a primary ankle lateral ligament reconstruction for chronic instability between 1989 and 1996. In addition to the ligament reconstruction, all patients had evaluation of the peroneal retinaculum, peroneal tendon inspection by routine opening of the tendon sheath, and ankle joint inspection by arthrotomy. A retrospective review(More)
A retrospective review was undertaken for 36 patients who underwent ankle arthrodesis. Nineteen patients underwent an arthroscopic ankle arthrodesis, and 17 patients underwent an open arthrodesis. Only patients with limited angular deformities were suitable candidates for an arthroscopic arthrodesis. The open arthrodesis group inclusion criteria were(More)
The extraosseus and intraosseous circulation to the first ray was evaluated by means of vascular injection techniques. The first metatarsal and metatarsophalangeal joint receive their blood supply from the first dorsal metatarsal artery, the first plantar metatarsal artery, and the superficial branch of the medial plantar artery. These three source arteries(More)
Fifteen patients (17 feet) with symptoms suggestive of plantar interdigital neuroma underwent magnetic resonance (MR) imaging at 1.5 T with a solenoid forefoot coil with an 8-cm field of view. Surgery was subsequently performed on six feet. Fifteen interdigital masses were identified with MR imaging. Five of these, in feet that underwent surgery, were(More)
The cases of eighty-three patients who had a soft-tissue tumor or tumor-like lesion in the foot or ankle were retrospectively analyzed to determine the relative frequency of the lesions and which factors, if any, could be used to identify them preoperatively. Seventy-two (87 per cent) of the lesions were benign, with ganglion cysts and plantar fibromatoses(More)
