title: Clinical evolution of sacral stress fractures: influence of additional pelvic fractures.
abstract: OBJECTIVE
  To evaluate the clinical evolution of sacral stress fractures in relation to the scintigraphic pattern and the presence of additional pelvic fractures.
  
  
  METHODS
  This was a retrospective study of 14 patients with sacral fractures.
  
  
  RESULTS
  Six patients had additional pelvic fractures. Four bone scintigraphic patterns were found. The resolution of symptoms was longer in patients with associated pelvic fractures (30 weeks v three weeks). No relation was found between the bone scintigraphic pattern and the time of evolution.
  
  
  CONCLUSIONS
  Associated pelvic fractures delay the resolution of symptoms in patients with sacral fractures, regardless of scintigraphic pattern.
