Claims20
A prosthesis for correcting a human flatfoot deformity comprising:
- a body configured for insertion between the neck region of the talus bone and the calcaneus bone in a region of the sinus tarsi, wherein the body is oriented such that, when inserted, a long axis of the body approximately parallels a medial-lateral human anatomical axis, and wherein the body has a base end provided with a concave depression and an end opposite the base, and wherein the body is tapered along its long axis such that a cross-sectional area of the end of the body opposite the base is smaller than a cross-sectional area of the body at the base.
