The Medacta^® Bipolar Head includes an outer shell made of stainless steel, studied to articulate directly in the patient acetabulum, an inner UHMWPE bearing surface, in which articulates the prosthetic femoral head.
The locking of the femoral head inside the bipolar head is easily achieved and assured thanks to an elastic internal retaining ring.
It is possible the change into a Total Primary Arthroplasty, without any damage to the head and the taper, simply pulling out the mobile head.
