We examined the complication of 94 patients who had undergone autogenous iliac bone grafting in spine surgery. Donar site pain, nerve injury, delayed wound healing, infection, hematoma and fracture were observed in 31.9%, 3.2%, 2.1%, 0%, 1.1%, 1.1%, respectively, but there were no serious complications. There was no significant difference between the complications of harvesting anterior iliac bone graft and that of posterior iliac bone graft. Strict observation of relevant anatomic considerations should help avoid these complications.
