  • Method of using a femoral surgical instrument
    Patent number: 9730706
    Abstract: A method of using an orthopedic surgical instrument assembly that includes an instrument handle configured to clamp a broach and femoral stem trial assembly. A depth stop is configured to removably couple to the instrument handle. When the broach and femoral stem trial are advanced into a medullary canal of a patient's femur, a substantially planar proximal surface of the depth stop is configured to engage the distal surface of the femur, determining the depth of the broach in the medullary canal. The proximal surface of the depth stop is parallel to the joint line, defining an oblique angle to the anatomical axis of the femur. The depth stop may be attached to the instrument handle at a number of positions to control the depth of the broach. The assembly may include a spacer plate removably coupled to the depth stop that distalizes the broach in the medullary canal.

  • Knee prosthesis system with standard and distal offset joint line
    Patent number: 8998996
    Abstract: A modular knee prosthesis system includes a femoral component having a stem and a sleeve. The system is modular, and provides the surgeon with the option of distally offsetting the joint line by controlling the relative axial positions of the stem and the sleeve. Alternative options include providing sleeves with tapered bores of different diameters, providing a shim to be placed between the sleeve and the stem and providing the stems as adapters having different diameters.
