Computer Navigation for Total Hip Replacement

Computer navigation for total hip replacement is a valuable addition for the surgeon in the operating room. This technology can level the playing field for all surgeons because it provides information in the operating room that allows a surgeon to overcome any deficiencies in 3-dimensional vision or experience. The optimal mating of the stem and the cup will improve long-term durability and will decrease the occurrence of immediate complications such as dislocation and long-term complications such as accelerated wear. Computer navigation alone cannot eliminate dislocation but must be combined with a hip replacement with a good head-neck ratio, preferably a large femoral head. The computer is best at this time for insuring correct component position and is weakest in information that restores biomechanical reconstruction of the hip.
