Cannulated Drill

This demonstrates how the guide bar for the femoral implant instrumentation is inserted. Once this is inserted into the center of the femoral neck, all of the preparation instruments will be guided by its position.

Cylindrical Preparation

This is the preparation of bone to shave off the sides of the femoral head. This is the critical part of femoral head preparation to avoid notching of the femoral neck

Dome Preparation

This is the shaving of the top of the femoral head, removing the arthritic bone so that it can be capped.

Trial

This demonstrates a good preparation of the femoral bone with an intimate fit of the femoral trial.

Final view of the femoral head

This shows the top of the femoral head, once it has been prepared for the femoral cap. There are some holes drilled in the top of the bone to allow for interdigitation of cement to provide more stability. There are no major structural defects in this femoral head.
