title: Sacral insufficiency fractures--rare complication of pelvic radiation for rectal carcinoma: report of a case.
abstract: OBJECTIVE
  The report contained herein presents a patient who developed severe back pain because of bilateral sacral insufficiency fractures after pelvic radiation for rectal carcinoma.
  
  
  METHODS
  This is a case report and review of the literature for a rare complication of pelvic radiation.
  
  
  RESULTS
  The patient was diagnosed by computerized tomography and radionuclide bone scans. Bed rest and analgesia followed by rehabilitation provided good relief of the symptoms.
  
  
  CONCLUSIONS
  A rare complication of pelvic radiation is insufficiency fractures of the pelvis. Early detection is important, because significant morbidity may result from delaying treatment. Unawareness of this complication may lead to diagnostic difficulties and unnecessary work-up.
