Donor site pain from the ilium. A complication of lumbar spine fusion.

Chronic pain at the donor site was reported by 25% of 290 patients who had undergone anterior lumbar spine fusion for low back pain. Donor site pain has characteristic clinical features, may be severely disabling and is stubbornly resistant to treatment. The highest prevalence was in patients who had a tricortical full thickness graft taken through a separate incision overlying the iliac crest. Patients with a clinically unsatisfactory result from the spine fusion also had a significantly higher prevalence of donor site pain.
