title: Extensive late bone necrosis after postoperative orthovoltage irradiation of breast carcinoma. Report of a case.
abstract: Extensive osteonecrosis of the clavicle, scapula and humerus was observed in a patient treated postoperatively 22 years earlier, with 250 kV roentgen rays, for breast carcinoma. Retrospective calculations based on the absorption in soft tissue and bone revealed very high absorbed doses in the bone (about 120 Gy).
