ABSTRACT:
A locking intramedullary alignment jig for use in bone resection, especially for the proximal tibial has an axially extending intramedullary rod for insertion into the medullary canal of the tibia. A slidable anchoring block is mounted on the rod for movement along the rod in the axial direction, which on the tibia is the proximal-distal direction. The anchoring block has a pivot point at one end thereof and a tooth portion at a second end thereof. A first rotating body is pivotally coupled to the pivot point on the anchoring block for rotation about a first axis. The rotating body includes a toothed locking member for releasable locking engagement with the toothed portion the anchoring block. A second rotating body, including a bone resection guide is connected to the first rotating body. Movement of the first and second rotating bodies allow rotation of the resection guide in both the flexion-extension and varus-valgus directions.
