Every year, almost 500 shoulder arthroplasties are performed in Denmark. About two-thirds are done due to fractures of the proximal humerus. Other common indications are rheumatoid arthritis and primary or secondary arthrosis. The prosthesis is fixed with or without bone cement. If the rotator cuff is lacking, an inverse total arthroplasty can be used, and in arthrosis/arthritis with good bone stock, a resurfacing prosthesis can be used. Good pain relief can be expected, but shoulder movement will usually be permanently inhibited.
