An artificial shoulder joint can be secured into the bone in a number of different ways. In essence, there are two main types of fixation: cemented and cementless:
- If the bone structure is no longer very stable, the shoulder surface replacement is attached using bone cement. Immediately after the operation, the shoulder endoprosthesis and bone are thus securely bonded.
- If the patient’s bone is of good quality, the artificial shoulder joint can be secured using a cementless technique. With such methods, the bone slowly grows into the shoulder endoprosthesis to form a strong joint after some time.
The correct choice therefore not only depends on the patient’s age but also on the nature of the bone. The surgeon decides upon the appropriate method together with the patient during the preoperative discussion.
