ABSTRACT:
An apparatus and method for determining offset-inset distances in the course of a total hip arthroplasty procedure. The apparatus includes a first attachment attachable to the superior eminence of the acetabulum, a second attachment point capable of being fixed to the femur at approximately the position of the greater trochanter, and preferably, a measuring device for measuring and noting the distance between the reference point and either the third or fourth fixed points.
