The kinematics of both the first metatarsophalangeal joint and the articulation of the hallux sesamoid bones with the metatarsal head were investigated with fifteen fresh-frozen below-the-knee amputation specimens using a radiographic technique. Six feet were of normal structural anatomy, six displayed hallux valgus, and three had hallux rigidus. Normal(More)
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 load distribution under the foot was investigated under various conditions by means of pressure-sensitive transducers. Weight-bearing pressures at the first and third metatarsal heads and at the heel were measured while subjects ambulated barefoot and while wearing numerous immobilization devices. The proportion of body weight imposed on the plantar(More)
The tarsal tunnel syndrome may be caused by extrinsic or intrinsic pressure on the posterior tibial nerve or its terminal branches. The specific symptoms depend on the extent of nerve involvement, and compression distal or proximal to the tarsal tunnel may result in variants of the syndrome. To define better the capability of MR imaging for evaluating this(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)
Lead markers were placed on various osseous structures of the talus and calcaneus in fresh amputation specimens to analyze the radiographic anatomy of the hindfoot. Analysis of the talocalcaneal articulations revealed that only the central one-third of the posterior subtalar joint can be visualized on the lateral projection, whereas the axial view profiles(More)
