Apparatus and method for anterior and posterior referenced sizing and distal femur resection

摘要

Apparatus for distal femur sizing and resection includes an adjustable sizer cut guide device formed by a sizer member, a femoral cut guide and a slide stone. The slide stone is provided to receive an intramedullary rod inserted into the femur. A first member and a second member are sequentially, removably attachable to the adjustable sizer cut guide device. The first member is an adjustable reference device provided for referencing. The second member is a distal cut guide which is attached to the adjustable sizer cut guide device after removal of the reference device, to position the distal cut guide on the femur. Readable scales on the adjustable sizer cut guide device and on the adjustable reference device, are matched to provide a size reference for a femoral prosthesis.
