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.

Techniques and reconstruction systems for ACL repair by providing cross-pin fixation of a graft within a tibial tunnel. The invention provides tibial fixation techniques according to which cross-pin fixation of a graft (for example, an Anterior Tibialis allograft) is achieved on the tibial side, close to the jointline, by a single incision and with cortical fixation.

Method of shoulder arthroplasty with adjustable angle of inclination

A humerus implant for a reverse shoulder prosthesis has a cup shaped body and a thread at the outside of the body. The thread has a plurality of fins with cut-outs between the fins. At least one fin has an inclined leading surface which helps in incising into the bone by rotating the body in an inward direction. Furthermore, at least one fin has a forward oriented undercut trailing surface blocking rotation in the outward direction.
