Abstract
A hand-held leg length discrepancy device in the form of an extended pin separated a fixed distance from a laser diode determines the length of a patient's leg after hip replacement surgery. A self-tapping first indication screw is partially inserted within the patient's pelvis prior to surgery, the extended pin is positioned on the screw and the laser beam is directed on the patient's leg. The location of the laser beam is recorded by means of an indelible ink mark or a drill hole. After surgery, the extended pin is positioned on the screw on the hip and the laser beam is again directed on the second mark or drill hole on the leg to determine any change in distance there between.
