Abstract
A sinus tarsi implant for the purpose of stabilizing and restoring motion between the talus and calcaneus while allowing normal motion and alignment. In a preferred embodiment, the implant is composed of a titanium alloy that is a combination of a cylindrical portion and an axially connected conical portion. The cylindrical portion has a surface with multiple parallel grooves that are each parallel to the transverse axis of the cylinder. The grooves are uniquely shaped with a perpendicular medial side and an angled lateral side. The implant is cannulated to enable use of a guide wire that insures proper alignment during insertion.
Claims14
A sinus tarsi implant for use in correcting anatomical alignment of a patient's ankle bone structure comprising:
- a cylindrical body portion consisting of a cylindrical side surface, a circular medial end and a circular lateral end, said medial and lateral ends being perpendicular to an implant central axis, said cylindrical side surface comprising a plurality of continuous circumferential grooves each perpendicular to the implant central axis, and
- a conical foot portion comprising a generally conical side surface, a circular top and circular base, said top being integrally connected, along the implant central axis, with the lateral end of the body portion,
- wherein said implant is capable of insertion into a patient's ankle and corrects anatomical alignment of the patient's ankle bone structure.
