From: Inverted reamer technique for bone grafting of the acetabulum: technical note
Shaving of the bone graft from the resected femoral head. a The resected femoral head was cut into an adequate size. b The side of the trabecular bone in the piece of the femoral head was reamed with the inverted reamer, and extra bone was removed with a leur. The black arrow indicates the movement of the inverted reamer. c A piece with a convex surface was created. This piece will be transplanted onto the roof of the acetabulum. Sclerotic bone is shown as a stripe pattern. The dotted line is the cut line
