A non-rotationally symmetrical, conical body with a self-locking seat connects the prosthesis to a shaft (5). The periphery of the conical body is formed and matched to a mating shape (15) in the shaft rotationally fixed relative to a longitudinal axis (9) and keyed by the amount of taper so that connection is releasable and repeatedly fixable in the same angular position. Two bearing bodies, which slide one another, are respectively connected to an upper arm (3) by the shaft and to a shoulder bone by a platform. |
