The subtalar joint complex is formed by the posterior talocalcaneal joint and the acetabulum pedis lodging the talar head. The basic motion at the joint is that of male ovoid surfaces moving over female ovoid surfaces and vice versa. The motion generated at the joint is that of flexion-supination-adduction or extension-pronation-abduction. The subtalar… (More)
During flexion and extension of the wrist, the total range of motion is determined by the radiocarpal and the midcarpal joints. The angular contribution of each carpal row has been differently quantitated by previous investigators. A radiographic investigation of the wrist motion in flexion and extension was undertaken in 55 normal wrists to determine the… (More)
A method of surgical correction of a fixed hammertoe deformity is presented. It incorporates the resection of the head of the proximal phalanx with an extensor tendon tenodesis to the dorsum of the proximal phalanx. The controlled tension in the extensor tendon provides the necessary stability. It alleviates the use of K-wire fixation.
A microsurgical dissection was performed on a clubfoot of a seven-month-old stillborn fetus with camptomelic dysplasia. The most important anatomic alteration was marked rotation of the calcaneus beneath the talus. The calcaneus was rotated around a vertical axis. Its anterior aspect was rotated medially, while its posterior aspect was rotated laterally. A… (More)
