Supracondylar femur fractures above an Insall-Burstein CCK total knee: A new method of intramedullary stem fixation

Supracondylar femur fracture above a well-fixed posterior cruciate substituting prosthesis may not allow the use of standard fixation methods because of the closed nature of the femoral box. The Insall-Burstein Constrained Condylar Knee femoral prosthesis (Zimmer, Warsaw, IN) possesses a closed box and the capability of modular femoral stems. A retrieval device aids the utilization of the modular ability of the femoral prosthesis to gain intramedullary fixation of supracondylar femur fractures above a well-fixed femoral component allowing restoration of alignment, length, preinjury range of motion, and function.
