A 58-year-old woman came to the outpatient clinic with exacerbation of chronic shoulder pain following a shoulder accident two week before. After the accident, she had been treated abroad with percutaneous K-wire fixation following the diagnosis of a displaced greater tuberosity fracture. X-ray images of the shoulder, however, showed calcification of the supraspinatus tendon fixed to the humerus, rather than a greater tuberosity fracture. After removal of the K-wires, the patient made a good recovery.
