Podiatric orthesis for orientation of the calcaneus and subtalar bones

Claim 1

An one-piece podiatric orthesis conceived according to anatomical and medical standards for the tridimensional plantar development of the foot of a patient, said orthesis acting simultaneously on both the calcaneus and subtalar of said patient's foot and comprising: (a) a rear part in the form of a cupola open at a forward end thereof, said cupola being designed and dimensioned for adapting to the calcaneus of the patient's foot and including: a cupola bottom wall having a rear edge, and inner edge and an outer edge, said cupola bottom wall being forwardly and upwardly uprighted according to an angle of about 30° with respect to the ground whereby to orient the calcaneus in the said forward direction and according to the said angle; and a cupola peripheral border extending upwardly from said bottom wall along the rear, outer and inner edges thereof with respect to said patient's foot, said cupola peripheral border having inner and outer portions corresponding to said inner and outer edges, said inner and outer portions being so shaped and oriented as to (i) neutralise any lateral shifting of the calcaneus and permanently reestablish proper axial alignment of the vertical axis of the calcaneus with the axis of the patient's leg, and simultaneously (ii) orient the longitudinal axis of the calcaneus in the direction of the fifth metatarsus of the patient's foot, (b) a median part projecting forwardly of and as an extension of said rear part, said median part including: a median part bottom wall disposed in the continuation of said cupola bottom wall and having inner and outer edges; and an inner border upwardly extending along the inner edge of said median part bottom wall, said inner border of said median part continuously extending the inner portion of said cupola peripheral border, and (c) a wedged structure defining a wedge tip for supporting and holding the subtalar of the patient's foot, said wedged structure being located at the level of said median part on the inward side of said orthesis and consisting of an integral extension of the inner border of said median part rising up to such a height as to reach and laterally sustain the inner, lower and forward part of the subtalar.
