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 8):
An arthroereisis implant comprising:\n an implant body;\n a first end portion and a second end portion opposite the first end portion; \n a first expansion wing pivotally coupled to the first end portion and including an outer surface and an inner surface, wherein the first expansion wing pivots outwardly upon application of a force to the inner surface; \n a second expansion wing pivotally coupled to the first end portion and including an outer surface and an inner surface, wherein the second expansion wing pivots outwardly upon application of a force to the inner surface; \n a first arm coupled to the first end portion and disposed between the first expansion wing and the second expansion wing, the first arm having an outer surface and an inner surface; \n a second arm coupled to the first end portion and disposed between the first expansion wing and the second expansion wing, the second arm having an outer surface and an inner surface; \n a first bore comprising:\n a threaded first portion having a first diameter, \n a second portion proximate the second end, \n a tapered third portion having a varying diameter; and \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 first bore in the implant body; wherein rotation of the expansion screw within the first bore causes the expansion screw to move linearly towards or away from the first end; wherein the linear movement of the expansion screw towards the first end causes the angled neck to engage the tapered third portion of the first bore to provide the internal force to the inner surfaces of the first expansion wing and the second expansion wing.
