ABSTRACT:
A surgical kit for performing a tibial osteotomy is provided, comprising a pair of mounting pins for attaching, an osteotomy guide in a predetermined relation to a tibia; an osteotomy guide, comprising a transverse slot, defining a transverse cutting plane, adapted to receive and guide a transverse cutting blade for making a transverse cut into the tibia, and a plurality of oblique slots angularly offset from the transverse slot, each oblique slot defining an oblique cutting plane, adapted to receive and guide an oblique cutting blade for making a selected oblique cut into the tibia, wherein the intersection of each oblique cutting plane with the transverse cutting plane defines a wedge of bone which may be removed from the tibia. Also included with the surgical kit are a compression clamp adapted to apply compressive forces to a first portion of the tibia above the transverse cut and to a second portion of the tibia below the oblique cut to draw the first and second portions together, and a fixation plate adapted to hold the portions of the tibia together during healing. A method for performing an upper tibial osteotomy is also provided which employs the osteotomy surgical kit.
