Abstract

An apparatus and a method are provided for an open wedge implant for open wedge osteotomies. The open wedge implant comprises a wedge body including a first expandable portion and a second expandable portion connected together by way of an intervening distal attachment. An expander is configured to separate the first and second expandable portions so as to increase a proximal thickness and a wedge angle of the wedge body. A proximal screw is configured to move the expander within the wedge body. Tightening the proximal screw draws the expander distally into the wedge body, thereby changing the open wedge implant from an initial, narrow wedge angle to an expanded wedge angle. In some embodiments, the open wedge implant is adapted for use in osteotomies performed in the feet, such as an Evans Procedure for lateral column lengthening, a Cotton Procedure for medial cuneiform opening wedge osteotomy, and the like.
