Abstract:
The invention is a subtalar implant able to expand after implantation. The subtalar implant has two or more expansion segments or wings. In all forms, the expansion wings are hinged on the distal portion of the subtalar implant which causes only the proximal portion of the wing to expand relative to the midplane of the implant. The expansion wings and the entire subtalar implant are threaded to prevent the implant from backing out of the sinus tarsi once implanted. In one form, the subtalar implant includes an integral expansion screw that, when rotated, expands the expansion wings. In another form, the subtalar implant includes a separate expansion screw that, when rotated, expands the expansion wings. The integral and the separate expansion screw includes a socket that accepts a like driver tool for rotating the expansion screw and expanding the expansion wings.

Claim (Index 16):
An implant comprising:\n an implant body;\n a first end portion and a second end portion opposite the first end portion; \n a first slot extending from the second end portion towards the first end portion; \n a second slot extending from the second end portion towards the first end portion; \n a first expansion wing formed by the first slot and including an outer surface and an inner surface, wherein the first expansion wing is pivotally coupled to the first end portion to pivot outwardly upon application of a force to the inner surface; \n a second expansion wing formed by the second slot and including an outer surface and an inner surface, wherein the second expansion wing is pivotally coupled to the first end portion to pivot outwardly upon application of a force to the inner surface; \n a first arm defined by and located between the first slot and the second slot, the first arm coupled to the first end portion and having an outer surface and an inner surface; \n a second arm defined by and located between the first slot and the second slot, the second arm coupled to the first end portion and having an outer surface and an inner surface; \n a bore at least partially defined by the inner surfaces of the first and second expansion wings and the first and second arms, the first bore comprising:\n a threaded first portion having a first diameter, and \n a second portion proximate the second end having a second diameter, \n wherein the second diameter is greater than the first diameter, \n \n an expansion screw having a threaded shaft, a head, and an angled neck between the threaded shaft and the head, the threaded shaft engages the threaded first portion of the bore in the implant body; wherein rotation of the expansion screw within the bore causes the expansion screw to move linearly towards or away from the first end; wherein the movement of the expansion screw towards the first end causes the angled neck to engage the angled inner surface portion of the first and second expansion wings to provide the internal force.
