Minimally invasive total hip replacement

摘要

A femoral implant (10) for total hip replacement includes a cage screw (2), a femoral head (1) and a base plate (3) provided between the cage screw and the femoral head, to minimize the stress transferred from the femoral head to the screw. The femoral implant may optionally include devices for lateral fixation (for example, internal and/or external screws for lateral fixation) and a device (4) for minimizing micro-motion that is integral to, and extends from, the cage screw.
