ABSTRACT:
Apparatus and method for interoperatively determining, during a trialing procedure conducted in connection with total hip arthroplasty at an implant site, a femoral neck length required in a femoral component to be engaged with an acetabular component of the prosthetic hip joint to be implanted at the implant site for establishing forces appropriate for proper articular engagement of the femoral component with the acetabular component, by moving a trial femoral head component and a trial femoral stem component relative to one another, while the trial femoral head component is engaged with an acetabular trial, to determine a measured distance corresponding to a trial distance between the trial femoral head component and the trial femoral stem component at which trial distance selected tensile forces are established in soft tissue at the implant site urging the trial femoral head component and the trial femoral stem component toward one another, the selected tensile forces corresponding to the forces appropriate for proper articular engagement of the femoral component with the acetabular component of the prosthetic hip joint, the trial distance corresponding to the required femoral neck length.
