Claim:
1. An osteotomy plate for maintaining the spacing of a wedge-like opening in bone, the osteotomy plate comprising: a body having a front side configured to face away from the wedge-like opening and a back side configured to face toward the wedge-like opening; at least two integral key elements extending out of the back side of the body and in a direction substantially perpendicular to the back side of the body for disposition in one or more keyholes formed into the bone within upper and lower wedge side surfaces of the wedge-like opening, wherein the at least two key elements are configured to conform and contact the one or more keyholes, wherein each of the key elements partially surround a window formed within the body of the osteotomy plate; and a plurality of mounting holes extending through the body for receiving fasteners therein, the mounting holes extending from the front side to the back side of the body, the mounting holes being formed in the body such that when the key elements are disposed in the one or more keyholes, the mounting holes direct the fasteners into bone on either side of the wedge-like opening, wherein the osteotomy plate is configured to extend into the wedge-like opening no further than a depth of the one or more keyholes; and wherein a first key element of the at least two key elements is formed by an upper arc, wherein the upper arc is formed such that an upper convex surface of the upper arc is configured to contact a corresponding keyhole, and a second key element of the at least two key elements is formed by a lower arc, wherein the lower arc is formed such that a lower convex surface of the lower arc is configured to contact a corresponding keyhole, and further wherein the first key element is spaced from the second key element.
