Tool for inter operative use during direct anterior approach total hip arthroplasty and related methods

19-33. (canceled)

A surgical guide tool for interoperative use during direct anterior hip replacement surgery to aid in detecting a change in LL and FO at the surgical site during final prosthetic configuration to the patient, the tool comprising:

• a. a femur contact member able to positionally and rotationally register on and with the femur by provision of at least two femur contact points of the femur contact member,
• b. a pelvis contact member able to positionally register on and with the pelvis,
• wherein the pelvis contact member and the femur contact member are (a) coupled together by a coupling in (a) a movable manner relative each other so that the pelvis contact member can positionally register with a reference on the pelvis when the femur contact member is positionally and rotationally registered with respective references of the femur prior to total femoral head removal and (b) a manner able to prevent movement between the pelvis contact member and the femur contact member so that after total femoral head removal the femur contact member can be returned to the surgical site and register at the references of the femur to visually detect change in LL and FO.
