An early comparative analysis of the use of fibular allograft versus autologous iliac crest graft for interbody fusion after anterior cervical discectomy.

Abstract

During a 2-year period (1988-1989), 23 cases of anterior cervical discectomy were performed with cadaveric fibular allograft instead of autologous iliac crest graft. The mean age of the patients was 35 years. There were 10 men and 13 women. In most cases, a one-level fusion was performed at the C5-6 level. The Smith-Robinson technique was used for discectomy and fusion, for both one- and two-level fusions. Evidence of radiographic fusion was achieved in 92% of the cases. Twenty-five cases of anterior cervical discectomy in which autologous iliac crest graft was used (1987-1988) were examined retrospectively for comparison. The mean duration of hospital stay was less in the allograft group (5.4 days vs. 7.25 days). In addition, postoperative pain was less in the allograft group because the allograft group did not have pain from the donor site. In conclusion, the use of fibular allograft for interbody fusion after anterior cervical discectomy can be performed with acceptable rates of fusion and less postoperative pain, as compared to the use of autologous iliac crest graft.
