Harvesting autogenous iliac bone grafts. A review of complications and techniques.

Autogenous bone grafts from the ilium are frequently harvested for purposes of bone union and/or stability. Although some donor site complications may be unavoidable, awareness of the anatomy and complications may aid in planning the approach and minimizing the risks. Documented donor site complications include pain, nerve and arterial injury, peritoneal perforation, sacroiliac joint instability, and herniation of abdominal contents through defects in the ilium. Strict observation of relevant anatomic considerations will help in avoiding these complications.
