Here are a series of videos demonstrating the femoral head preparation using the Birmingham Hip Resurfacing Instrumentation.

Central pin positioning using the McMinn guide for BHR

Conserve plus pin positioning using the European instrumentation

Implantation of an uncemented Biomet Recap – not the excellent bone preparation and the tight tolerances to fit the implant

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.

Chamfer Preparation
This demonstrates the shaving of the angled portion of the femoral implant

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.
