An apparatus is provided for an open wedge implant 100 for open wedge osteotomies. The open wedge implant 100 comprises a wedge body 104 including a first expandable portion 124 and a second expandable portion 128 connected together by way of an intervening distal attachment. An expander 108 is configured to separate the first and second expandable portions 124, 128 so as to increase a proximal thickness and a wedge angle of the wedge body 104. A proximal screw 112 is configured to move the expander 108 within the wedge body 104. Tightening the proximal screw 112 draws the expander 108 distally into the wedge body 104, thereby changing the open wedge implant 100 from an initial, narrow wedge angle to an expanded wedge angle. In some embodiments, the open wedge implant 100 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.
