US 8,709,052 B2 · Method and apparatus for performing an open wedge, high tibial osteotomy

Abstract

An osteotomy implant for disposition in a wedge-shaped osteotomy opening in a bone, the implant comprising: a body for disposition within the wedge-shaped osteotomy opening in the bone and supporting the bone while healing occurs; at least one key formed integral with the body for stabilizing the body relative to the adjacent bone while healing occurs; and at least one fenestration extending through the body for permitting bone growth through the implant. An osteotomy implant for disposition in a wedge-shaped osteotomy opening in a bone, the implant comprising: a body for disposition within the wedge-shaped osteotomy opening in the bone and supporting the bone while healing occurs; and at least one key formed integral with the body for stabilizing the body relative to the adjacent bone while healing occurs; wherein at least a portion of the body and the at least one key are formed out of a relatively strong, load-bearing material whereby to stabilize the bone during healing; and further wherein at least a portion of the body is formed out of a bone growth-promoting material whereby to enhance bone healing across the osteotomy opening in the bone.

Dependent claims

A method for performing an open wedge, high tibial osteotomy, the method comprising:

providing an osteotomy implant, the osteotomy implant comprising:
a body for disposition within the wedge-shaped osteotomy opening in the bone and supporting the bone while healing occurs;
and
at least one key formed integral with the body for stabilizing the body relative to the adjacent bone while healing occurs;
cutting the tibia along a cutting plane, with the cut terminating at a boundary line;
forming at least one keyhole in a surface of the tibia adjacent to the cut that corresponds to a shape of said at least one key;
moving the bone on either side of the cut apart so as to form a wedge-shaped osteotomy opening in the bone;
and
positioning the osteotomy implant in the wedge-shaped osteotomy opening in the tibia, wherein the body of the osteotomy implant is disposed within the wedge-shaped osteotomy opening in the tibia and the at least one key is disposed in the at least one keyhole formed in the surface of the tibia.
