Abstract
A distal femoral cutting block apparatus for use in knee surgery includes an instrument body that has generally flat opposing parallel surfaces and a plurality flat peripheral surfaces to form a generally rectangular body. The body provides anterior and posterior surfaces and medial and lateral surfaces. The transverse slot carries a valgus module that is movably disposed in the slot. The valgus module includes a tubular sleeve member having a pair of opposed sides that abut the body at the slot. A portion of the tubular sleeve member is threaded and the threaded portion extends away from the body. An open ended bore extends through the tubular member. The open ended bore of the tubular sleeve member of the module accommodates an intramedullary rod that fits the patient s intramedullary canal. A lock nut engages the threaded section of the module for locking the module in a desired position on the cutting block body by engaging the threaded portion and the instrument body to rigidly affix them together.
