Different models of prosthetics
Since 1960, the design and materials of prostheses have been progressively evolving.
As regards the cup, most orthopaedic surgeons currently choose the uncemented implant, for which the immediate stability is provided by the “point contact” (press-fit) or “pressure” on the surrounding bone. The choice of the stem depends on the quality of the bone: in the case of osteoporotic bone (poor bone quality) it is advisable to choose a cemented implant.
A further distinction between the different hip arthroplasty models used today is given by the different materials for coupling the femoral head-cup insert.
