 The Furlong Evolution design is based on the tried and tested Furlong H.A.C implant but with some modifications. It still retains its full H.A.C coating and is much shorter in length. This potentially makes it easier to introduce into the femoral canal, which may result in less soft tissue damage and lower rate of femoral fracture. This would be very beneficial, should revision implant replacement be required at a later date. This potential characteristic has been highlighted as an important component of determining the clinical effectiveness of a total hip replacement.
