DISTAL RESECTION SYSTEMS AND METHODS

摘要

The present disclosure relates to systems and methods for preparing a distal end of a femur for receiving a knee prosthesis. A method can include installing a valgus guide onto an intermedullary rod, coupling a drill guide with said valgus guide, resting a boom tip of said drill guide on a high part of the femur, drilling a hole into a distal portion of a medial condyle using a first drill hole of said drill guide and drilling a hole into a distal portion of a lateral condyle using a second drill hole of said drill guide, and, subsequent to drilling the first and second drill holes, resecting the distal portion of the medial condyle of the femur and the distal portion of the lateral condyle of the femur. A system can include a valgus guide, a drill guide, and a resection tower, among other things.

1. A method for preparing a distal end of a femur for receiving a knee prosthesis, the method comprising:
installing a valgus guide, including a first aperture for slidably accepting an intramedullary rod and one or more second apertures for accepting a drill guide, onto the intramedullary rod such that it contacts at least a distal portion of a medial condyle of the femur; coupling said drill guide with said valgus guide, including sliding one or more drill guide posts into said one or more second apertures of the valgus guide and locating a first drill hole of the drill guide substantially over the distal portion of the medial condyle of the femur and a second drill hole of the drill guide substantially over the distal portion of the lateral condyle of the femur; resting a boom tip of said drill guide on a high part of the femur to align said first drill hole and said second drill hole; drilling a hole into the distal portion of the medial condyle using said first drill hole and drilling a hole into the distal portion of the lateral condyle using said second drill hole; and resecting the distal portion of the medial condyle of the femur and the distal portion of the lateral condyle of the femur subsequent to drilling said first drill hole and said second drill hole.
