The invention relates to a base platform () for an artificial joint, in particular for an artificial shoulder joint, wherein the platform can be anchored on the bone and serves as a support for an artificial joint component () that can be provided both in the form of a shell component () for an anatomical configuration and also in the form of a ball component () for an inverse configuration, and wherein different joint components can be mounted on the platform.

Base platform for an artificial joint

The invention relates to a shoulder joint prosthesis comprising two cooperating bearing bodies, a shaft and a coupling for the connection of the shaft to one of the bearing bodies, with a support member adjoining the lower side of the bearing member connectable to the shaft, an outer support surface of said support member at least partly filling a gap present between the bearing body and the shaft in the state connected to the shaft such that the growing together of bone fragments is promoted.

Shoulder joint prosthesis

A shoulder joint prosthesis is shown having two bearing bodies () which slide on one another and which can be respectively connected to the upper arm () by a shaft () and to the shoulder bone () by a platform (). When the connection to the shaft () is brought about by a non-rotationally symmetrical, conical body () with a self-locking seat, with its periphery () being form matched to a mating shape () in the shaft () which is rotationally fixed relative to a longitudinal axis () arid keyed by the taper so that the connection is releasable and repeatedly fixable in the same angular position, large forces can be transmitted by the connection.
