Structurally the foot is equivalent to a twisted plate. The hindpart is located in the sagittal plane and the forepart in the transverse plane. The transition induced by the twist creates the transverse and the longitudinal arches. Under vertical loading of the foot plate by the tibiotalar column, compressive forces are created on the dorsum and tensile(More)
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 simplified, predictable method of peripheral nerve block at the ankle and foot with a long acting anesthetic agent bupivacaine (Marcaine) 0.5% is presented. Combined with the use of a pneumatic tourniquet it allows the performance of mid and forefoot surgery on an inpatient or outpatient basis. It alleviates the risks of general or spinal anesthesia and(More)
