title: Donor site morbidity after bone harvesting from the anterior iliac crest.
abstract: OBJECTIVE
  Autologous bone grafting is a common, standard procedure in maxillofacial surgery. We investigated complications of harvesting bone from the anterior iliac crest.
  
  
  METHODS
  A retrospective analysis with a 2-year observational period included 75 patients who had undergone iliac bone grafting. Two techniques were examined: the closed osteotomy using a cylinder osteotome (Shepard) and an open procedure with a saw.
  
  
  RESULTS
  One major complication, a fracture of the anterior superior iliac spine, was observed (0.7%). Regarding long-term morbidity, 3 patients (4%) suffered from persistent pain and 2 (2.7%) from persistent sensory disturbance. A correlation by gender showed greater severity of pain directly after graft harvesting in women (P(Wilcoxon) < or = .001). Harvesting of corticocancellous blocks caused more pain than with the cylinder osteotome (P(Median) < or = .07).
  
  
  CONCLUSIONS
  The morbidity after iliac crest harvesting was found to be moderate to low, but the procedure is still necessary and frequently used.
