Abstract
Official abstract text for this publication.
A talar implant is disclosed. The implant comprises a body comprising a bone contact surface and an articulation surface. A stem extends longitudinally from the bone contact surface. The stem comprises one or more features sized and configured to prevent rotational movement, anterior/posterior movement, and medial/lateral movement. The stem is configured to be received within a hole a talus.
First claim
Opening claim text (preview).
What is claimed is: 1 . An implant, comprising: a body comprising at least one bone contact surface and an articulation surface; a stem extending longitudinally from the at least one bone contact surface; and a spline formed about the stem a plurality of teeth configured circumferentially about said stem so as to provide anterior/posterior, rotational, and medial/lateral stability. 2 . The implant of claim 1 , wherein the plurality of teeth are configured to interface with a corresponding plurality of grooves that define a hole in bone. 3 . The implant of claim 1 , wherein the spline is sized and configured to be received within a channel formed in a bone to prevent anterior/posterior movement, rotational movement, and medial/lateral movement. 4 . The implant of claim 2 , wherein the spline comprises a plurality of equally spaced teeth disposed about a circumference of the stem. 5 . The implant of claim 1 , wherein the body defines at least one instrument hole sized and configured to receive an instrument for deploying the implant therein. 6 . The implant of claim 1 , wherein the stem extends a predetermined distance from the body, and wherein the predetermined distance is less than a thickness of the body. 7 . The implant of claim 1 , wherein the articulation surface is sized and configured to mimic a talar dome.
