Abstract

An extramedullary femoral clamp guide system enables cutting a portion of the distal end of a femur perpendicularly to an ideal weight bearing axis of the femur as viewed in an antero-posterior image of the femur and cutting the frontal surface of a distal end part of the femur in parallel to the frontal surface of the distal end part of the femur. The extramedullary femoral clamp guide system comprises a first clamp (2) having a pair of holding members (6a, 6b) for clamping a first portion of a distal end part (61) of a femur therebetween, a second clamp having (3) a pair of holding members (11a, 11b) for clamping a second portion of the distal end part (61) of the femur nearer than the first portion of the same to a proximal end of the femur, a connecting mechanism (4) connecting the first and the second clamp (2, 3) so that the first clamp (2) can be translated relative to the second clamp (3), and an extramedullary rod (5) connected to the connecting mechanism (4) so as to extend outside the femur on a straight line passing a middle point between the pair of holding members (6a, 6b) of the first clamp (2) and that between the pair of holding members (11a, 11b) of the second clamp (3).
