Hip replacement joint

The hip replacement joint has an outer support shell (1) which is fused to the bone structure and a separate inner shell (2) which forms the socket for the hip joint. The inner shell is located in the outer shell via two conical taper profiles, with the slope of the outer taper of the inner shell steeper than that of the inner taper of the outer shell. This ensures that the contact region (4) is nearer to the support structure of the outer shell. The tapers are between 18 deg and 20 deg with the arc difference between the tapers between 0' and 20'. The outer shell has one or more recesses (10) into which a tool can be placed to prise the inner shell away from the outer shell, for replacement.

Schaftadapter zum Verbinden einer Stumpffassung mit einem Prothesenschaft

Künstliches Gelenk einer Prothese

Prostheses with artificial joints have only a few metallic and ceramic materials whose compatibility with human or animal tissue has been established. These materials, however, cannot be combined with one another in any manner if a friction pairing occurs as a result, for example, in the case of artificial joints. With artificial joints, joint partners are required to have good mechanical properties as well as tribological properties. According to the invention, a sintered material is thus provided which is comprised of zircon oxide with an addition of 0.1 to 40 wt. % aluminum oxide. This sintered material enables an artificial joint of a prosthesis whose other ceramic materials are comprised of aluminum oxide or zircon oxide with the given proportions of aluminum oxide to be assembled with joint partners.

Spacer for vertebral prosthesis - has oval shaped, concentric, telescopic members rotated into locked position to engage threaded portions

The distance piece is for insertion in a vertical prosthesis, and for embedding in cement to form a connection with a section of bone. It consists of two sections (1,2) which slide telescopically. The upper section (1) has a tube (5) forming a skirt with inner threads, and the lower section (2) has an externally threaded stem. Both are oval in shape, permitting the sliding action to give a required overall length. By fixing the lower section and turning the upper section, the threads engage, locking the two sections together. The upper section has flats (17) near the bottom, and the lower section has a hole (16) near its bottom. This enables a tool to be used, having a forked jaw to grip the flats, and a projecting pin to fit in the hole, in order to rotate the upper section. The tool has handles with a tooled locking bar between them.
