It was reported that at the time of starting the preparation of the acetabulum, two problems arose altogether.The first caused by the cutting equipment, it was reported that it did not have enough torque.The second problem was with the acetabular reamers, they don't have the necessary edge.Overall, the result was that when trying to work the bone, the reamer did not move inside the acetabulum.By decreasing the pressure exerted on the cutting equipment, the instrument made an uncontrolled movement that caused a fracture in the upper part of the acetabulum.
