Abstract:
1. A subtalar implant device adapted for implantation between a talus and a calcaneus of a foot, the subtalar implant comprising: a core region having a first end configured for insertion into the foot, a second end, a core exterior that extends between the first end and the second end, and a longitudinal axis, the core exterior sized and shaped to be positioned substantially between the talus and the calcaneus, and the core exterior having a core angle relative to the longitudinal axis; a threaded region formed on and extending away from the core exterior, the threaded region including threads having an outer edge with a plurality of edge points located in a single plane that is coplanar with the longitudinal axis, the edge points comprise a multiple edge angle relative to the longitudinal axis, wherein the core angle is less than the multiple edge angle and greater than zero degrees over at least a portion of the core region between the first end and the second end, wherein the core region and the threaded region are integrally formed as a unitary structure, wherein the outer edge includes an edge width, and wherein the edge width increases along at least a portion of the threads from the second end toward the first end; and an implant guide adapted for insertion completely through a longitudinal aperture in the core region to guide the subtalar implant between the talus and the calcaneus.
