ABSTRACT:
A measuring device and method for use in total hip replacement. A measuring member or arm is pivotally attached to two Steinmann pins in the ilium and a single Steinmann pin is placed in the femur next to the measuring arm. The measuuring arm is made level by the use of a bubble level at a predetermined position and measurements taken to locate the femur with respect to the ilium. This procedure is done after the hip replacement, and measurements taken again. The results are compared to see if the ilium and femur are properly positioned or need adjustment.
