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.
