Method of using a trial acetabular cup for insertion of an acetabular prosthesis
A trial acetabular cup having a signal generating device located thereon.
1. A method for inserting an acetabular cup prosthesis into an acetabulum comprising:
inserting a trial acetabular cup into the acetabulum, the trial acetabular cup having a signal generating device mounted directly on the cup, wherein the signal generating device is a laser generating device configured for emitting a laser signal away from the cup when the cup is in the acetabulum,
activating the signal generating device to produce a visible laser signal;
placing a mark where the visible laser signal impacts on a surface;
removing the trial acetabular cup;
positioning an acetabular cup prosthesis with an insertion tool in the acetabulum;
activating a light emitting device on the tool to produce a light signal;
aligning the light signal with the mark; and
inserting the acetabular cup prosthesis.
2. The method of claim 1 further comprising:
inserting a guide pin into the pelvis;
locating a target on the guide pin;
removing the trial acetabular cup;
positioning an acetabular cup prosthesis with an insertion tool in the acetabulum;
activating a light emitting device on the insertion tool to produce a light signal;
aligning the light signal with the target; and
inserting the acetabular cup prosthesis.
