title: Occult posterior pelvic ring fractures in elderly patients with osteoporotic pubic rami fractures.
abstract: OBJECTIVE
  To evaluate postoperative walking status of elderly patients with osteoporotic pubic rami fractures with or without posterior pelvic ring fractures.
  
  
  METHODS
  33 women and 4 men aged 66 to 95 (mean, 85) years presented with osteoporotic pubic rami fractures after a fall. 22 (59%) of the patients had additional posterior pelvic ring fractures (9 had lateral compression type-II fractures involving the ilium and 13 had lateral compression type-I fractures involving the sacroalar region). Seven of the 9 patients with lateral compression type-II fractures underwent open reduction and internal fixation using plates and/ or screws. The remaining 30 patients were treated conservatively.
  
  
  RESULTS
  Postoperative walking status was similar in elderly patients with osteoporotic pubic rami fractures with or without posterior pelvic ring fractures.
  
  
  CONCLUSIONS
  Posterior pelvic ring fractures are easily missed in elderly patients with pubic rami fractures. Routine computed tomography of the pelvis is useful in making the diagnosis.
