Each year, about 80 elbow arthroplasties are performed in Denmark. Approximately two thirds are done due to rheumatoid arthritis, the others due to comminuted fractures of the elbow, especially in elderly patients. The prosthesis is fixed with or without bone cement, and there are two different types of elbow prostheses: linked, in which the humerus and ulna are connected by a sloppy hinge, and non-linked, in which stability is dependent on the soft tissues of the elbow. Good pain relief can be expected, but the range of motion will usually be permanently affected.
