title: Sacral fatigue fracture in a female runner: a case report.
abstract: OBJECTIVE
  This case report describes and discusses the clinical presentation, diagnosis, and management of a patient with a sacral fatigue fracture.
  
  
  METHODS
  A 26-year-old female long-distance runner presented with nonspecific low-back and buttock pain that prevented her from training.
  
  
  RESULTS
  Radiographic findings on the patient's lumbar spine and pelvis were interpreted as normal. Single-photon emission computed tomography and magnetic resonance imaging were performed, revealing a fatigue fracture of the left sacral ala. The patient discontinued training for 6 months and gradually returned to running.
  
  
  CONCLUSIONS
  A high index of suspicion should prompt investigation with skeletal scintigraphy, computed tomography, or magnetic resonance imaging. Sacral stress fractures may respond well to conservative measures if diagnosed in a timely fashion.
