With a mean follow-up of 3 (1-6) years, we report on 21 patients who underwent multiple level cervical fusion, using autologous iliac crest grafts.
Dissectomies were performed in 14 patients and corpectomies in another 7. Instrumentation was used in all patients with corpectomies and in 2 patients who underwent 2-level and 3-level dissectomies. Non-union occurred in 1 patient at 1 level. Graft displacement requiring reoperation was observed in 2 patients with massive corpectomies, in 1 of them as a consequence of trauma. In both patients complete bony fusion was obtained after reoperation and no other complications were observed.
We conclude that the success rate with multiple-level fusion is comparable to that of single-level fusion when adequate fixation is achieved.
