Autologous iliac crest bone graft harvest results in minimal major morbidity when regional anatomy is respected and careful technique is observed. The identification of patients at risk for minor complications suggests that allograft may be appropriate in these patients; however, prospective comparison is required to identify whether graft material or technical factors determine fusion success and relative benefit.
