Abstract:
1. An osteotomy guide, for use in controlling a cut by a saw blade in a bone, wherein the prospective cut has a desired location and a desired length, comprising: a frame, having a top and a bottom, the frame having an outer frame section and an inner frame section, each of said frame sections having a guide pin sleeve and an open end opposite from the guide pin sleeve, the guide pin sleeves each have a guide pin bore extending vertically through the guide pin sleeve, the guide pin sleeves and guide pin bores are substantially parallel and vertical, wherein a distance between the guide pin sleeves can be adjusted by sliding the inner frame section within the outer frame section, wherein the outer frame section has a pair of outer panels extending between the guide pin sleeve and open end of the outer frame section and defining an elongated outer slot therebetween, the outer slot extends fully between the top and bottom, the inner frame section having a pair of inner panels extending between the guide pin sleeve and open end of the inner frame section and defining an elongated inner slot therebetween, the inner slot extending fully between the top and bottom, the inner panels extending between the outer panels of the outer frame with the inner frame panels substantially parallel to the outer frame panels so that the inner slot and outer slot form a main slot which is longitudinally continuous substantially between the two guide pins sleeves, for allowing the saw blade to extend vertically through the main slot fully from the top to the bottom such that the saw blade is constrained in both longitudinal and transverse directions by the main slot, wherein at least one of the inner frame panels has a lateral protrusion, extending substantially from the open end of the inner frame section substantially to the guide pin sleeve of the inner frame section, wherein at least one of the outer frame panels has a side slot extending from the open end of the outer frame section substantially to the guide pin sleeve of the outer frame section, and wherein the lateral protrusion extends within the side slot to direct slidable movement of the inner frame section with respect to the outer frame section; and a pair of guide pins, which selectively extend through the guide pin sleeves which direct the guide pins into the bone in a parallel relationship prior to cutting.
