The concept Designed for the management of proximal femoral fractures. Total hip replacement is often the only alternative for the treatment of femoral neck fractures, particularly in the elderly. The LYOS Hip Fracture System is specifically designed to manage femoral neck fractures, simply and effectively. The LYOS Hip Fracture System ensures leg length equalisation through proper preoperative planning and use of a dedicated and innovative instrument system. The LYOS implant range consists of three Charnley-type femoral stems manufactured from nitrogen stainless steel, M30NW. The entire surface of the stem is polished to a mirror smooth finish, Ra (0.02 ; 0.05). 132° Neck-shaft angle, three neck lengths, long distal stem, two proximal holes for trochanter reattachment with cerclage wires (where necessary).
