Pelvic bone complications and focal red marrow changes were identified in a total of 38 patients (31.1%). Pelvic insufficiency fracture was diagnosed in 17 patients (13.9%, with a total of 64 lesions) and radiation osteitis was diagnosed in 5 patients (4.1%, with a total of 13 lesions). Avascular necrosis of the femoral head was detected in one patient (0.8%). Focal red bone marrow changes were seen in 15 patients (12.3%). The median time from the end of radiotherapy to the diagnosis of pelvic bone complications or changes was 25 months (range 2\u201345 months). The 1\u2010, 2\u2010, and 3\u2010year cumulative incidences were 22%, 41% and 49%, respectively. The distribution of insufficiency fractures was as follows: sacral ala, sacral body, ilium, acetabulum, pubis and lumbar spinal vertebra. The distribution of radiation osteitis was as follows: sacral ala, ilium and pubis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
