摘要:
The present invention generally relates to computer-assisted joint replacement surgery, and corresponding navigation systems. The systems and methods presented find particular use in performing hip replacement surgery. For example, in one embodiment, there is provided a system and method for: (a) measuring a pre-dislocation positional relationship between a patients pelvis and the patients femur (b) performing a post-dislocation femoral registration of the femur (c) tracking the position of the femur relative to the pelvis during a reduction procedure (d) calculating a change in leg length and a change in offset, after the reduction procedure, based on the femoral registration and the pre-dislocation positional relationship between the pelvis and the femur and (e) conveying the change in leg length and the change in offset.
