Structure of the hip endoprosthesis

The artificial hip joint

Artificial hip joints are available in various designs and materials. Our orthopaedic surgeons provide the patient with detailed information of the various systems and find the best replacement joint for the individual needs of the patient.

With the various prosthetic types, a distinction is made between surface prosthetics, short shaft prosthetics and standard prosthetics. The standard prosthetic is made up of four components and its composition is the same as the human hip.

The prosthetic socket replaces the natural acetabular socket. As a rule it is made of metal (titanium or cobalt-chrome alloys) and is fixed in bones without cement. A socket inlay is inserted into this metal socket.

The socket inlay, the later sliding partner for the prosthetic head, may consist of plastic (polyethylene), metal or porcelain. It is optimally fitted into the prosthetic socket.

The femur head replacement (prosthetic head) is the counterpart of the socket inlay and thus determines the sliding behaviour of the prosthetic. It consists of metal or porcelain. Depending on the material combination of the socket inlay and prosthetic head, polyethylene/metal, polyethylene/porcelain, porcelain/porcelain and metal/metal sliding pairings are possible. The surfaces of the sliding pairs are very smooth – they enable very low-friction in the artificial joint.

The prosthetic shaft consists of metal (titanium or cobalt-chrome alloys) and is inserted in the thigh bone. At the top end there is a cone, onto which the femur head is mounted.

With surface replacement, the defective surface of the femur head is replaced with a metal cap and the socket is replaced with a metal dish. If the bone substance is good, we increasingly use bone-protecting short shaft prosthetics.

Endoprosthetic surgery hours

The Waldkrankenhaus Eisenberg performs more than 1,000 total endoprosthetic hip operations per year. Our hospital is therefore one of the most experienced endoprosthetic centres in Germany. Our patients also benefit from this comprehensive, long-term practical experience in the endoprosthetic surgery hours.
