We would like to clarify the diagnosis of a patient who suffered from shoulder deformity after a minor trauma. The patient was a 58-year-old woman who had a history of breast cancer. The operation was performed in 1990 and radiation was followed for 8 weeks. In 1999 slight pain of left shoulder appeared, when she picked up a 10 kg package in her left hand. After which she was massaged by a bone setter for 3 days and her shoulder pain increased. The X-ray findings on February 8 showed inferior subluxation of the shoulder. A closed reduction and external fixation were performed for 3 weeks. In November 1999, a radiation ulcer appeared in her left breast. A skin grafting was performed in our hospital in May 2000. She consulted our clinic complaining of shoulder pain. The X-ray showed there was glenohumeral osteoarthritis in her left shoulder. We operated on a total shoulder arthr oplasty and the results after surgery were good. We thought the cause of this case was glenohumeral ostearthritis by osteoradionecrosis.
