Abstract

A humeral component of a shoulder prosthesis encloses a stem module which has a shank and an upper shank portion with a stem support surface. A joint adapter is adapted to hold either a liner or a spherical cap. The joint adapter has an adapter support surface which interfaces with the stem support surface. Further, the stem support surface and the adapter support surface have corresponding radial arc shaped sections which allow positioning of the joint adapter against the stem module at different inclination angles. For fastening the joint adapter to the stem module, a bolt or screw is provided.
