Failed Anatomical Shoulder Arthroplasty: Case Example 1
Four-part fractures in elderly patients are often treated by shoulder arthroplasty. Depending on the status of the greater tuberosity, anatomical or reverse shoulder prosthesis can be used. If the anatomical prosthesis is used, the greater tuberosity must be fixed to the implant or to the humeral shaft in order to enable normal function of the rotator cuff. Non-healing of the greater tuberosity will signify failed function of the shoulder.
