Method and instruments for resection of the distal femur
First Claim
1. A distal femoral resector for use in resecting the distal femur of a leg, said distal femur having a substantially flat surface formed on the anterior femoral cortex thereof, said resector comprising:
- (a) a base of substantially T-shaped configuration and adapted to be placed in overlying relation to said substantially flat surface, siad substantially T-shaped configuration being defined by a proximal leg portion and a distal transverse portion;
(b) an intercondylar notch pin attached to a distal side of said transverse portion; and
(c) a rotating rod rotatably mounted through said leg portion and including means for attaching said base to said distal femur, said rod being rotatable to facilitate firm and flush attachment of said base to said substantially flat surface.

Abstract
The present invention relates to a method and instruments for resection of the distal femur. The instruments include a distal femoral resector and a femoral alignment guide/rod. The distal femoral resector is designed to be attached to the distal femur on a plane filed on the anterior femoral cortex. The distal femoral resector includes a feeler gauge laterally adjustable to adapt to the intercondylar notch of the particular patient and further includes a rotating rod having openings therethrough for fastening pins, which rotating rod is designed to facilitate the placement of the resector on the anterior femoral cortex in a flush manner. The femoral alignment guide/rod includes a plate insertable within a slot in the resector designed for the insertion of the cutting tool and further includes a pivotable rod which may be utilized to align the resector with the mechanical axis of the leg. The rod may then be pivoted to a position facilitating the insertion of a fastening pin through the resector. The method of operating using these instruments is also disclosed.
