A shoulder prosthesis comprising a socket and a condyle that cooperates
with the socket. The condyle also cooperates with a base plate facing the
scapula similar to a clamping connection. The condyle is plugged onto the
base plate by means of a receptacle that is embodied on the condyle. The
base plate can be anchored to the glenoid fossa of the scapula with the
aid of two peg-type protrusions.
