A medical device is provided for attachment to a patient's femur to treat a fracture in the distal region of the femur, in a patient with an artificial knee joint. The apparatus includes first and second elongate plates for attaching to the femur at the location of the fracture. The plates include coupling means to rigidly coupling the plates to the femoral component of the artificial knee joint. The apparatus further includes a transverse link for connecting the first and second plates together in a spaced apart relationship to form a rigid linkage between said plates. The invention further includes a system for treating a fracture of the femur, especially in patients with weak bones, by attaching such plates in an opposed spaced apart relationship on the lateral and medial sides of the femur, and fastening the lower ends of the plates to the femoral component of the knee. The transverse link is engaged to form a monolithic, rigid structure for bracing the femur.

La présente invention concerne un dispositif médical destiné à être fixé à un fémur de patient présentant une articulation de genou artificielle. Ledit dispositif vise à traiter une fracture dans la région distale dudit fémur. Il inclut une première plaque allongée et une seconde plaque allongée destinées à être fixées au fémur à lemplacement de la fracture. Lesdites plaques incluent des moyens de couplage permettant de coupler de manière rigide les plaques au composant fémoral de larticulation de genou artificielle. Lappareil inclut en outre un lien transversal permettant de raccorder ensemble la première plaque et la seconde plaque dans une relation espacée, afin de former une liaison rigide entre lesdites plaques. Linvention porte en outre sur un système destiné à traiter une fracture du fémur, en particulier chez des patients ayant des os fragiles, en attachant ces plaques dans une relation espacée opposée sur le côté latéral et le côté médial du fémur, et en fixant les extrémités inférieures des plaques au composant fémoral du genou. Le lien transversal est inséré pour former une structure monolithique rigide destinée à maintenir le fémur.
