Podiatric orthesis for orientation of the calcaneus and subtalar bones

摘要

A podiatric orthesis for the tridimensional plantal development of the foot of a patient, which orthesis is conceived according to medical anatomical standards. It comprises a base having a rear part in the shape of a cupola, dimensioned for adapting to the calcaneus, and a median part projecting forwardly of and as an extension of the rear part. The latter is designed to hold the vertical axis of the calcaneus coaxial with the axis of the leg. The bottom of the cupola rises forwardly at an angle of about 30 with respect to the ground to orient the calcaneus forwardly and at the same angle. The longitudinal axis of the rear part is oriented toward the fifth metatarsus of the foot so as to likewise orient the calcaneus. The median part has an inner border which concavely curves to support the subtalar.
