ABSTRACT:
A method and apparatus for use in surgical hip replacement procedures for ensuring that the replacement hip joint components are properly sized. A flexible measuring cable is attached to the superior eminence of the exposed acetabulum and extended inferiorly to be aligned with a specific point on the femur. A marking indicator carried by the flexible cable is positioned to provide a reference distance between the fixed points on the acetabulum and the femur. Trial femoral implants can be selected to have proper neck length by extending the flexible cable attached at one end to the acetabulum toward the marked position of the femur so that the marked position is aligned with the indicator fixed to the cable. The cable may again be extended between the fixed point on the superior eminence of the acetabulum and the marked point of the femur and greater or lesser length femoral neck components may be selected until the correct length is achieved.
