Abstract: Objective\ Treatment of spondylolisthesis using freeze dried femoral ring allografts plus morselled cancellous autografts (called as composite cortical ring) by anterior lumbar interbody fusion (ALIF). Methods\ Fourteen patients were treated by this procedure, there were six males and eight females. The age of the patients range from 40 to 56(average 46). Ten segments were of grade Ⅱspondylolisthesis, five segments were of gradeⅠ. Ten patients were treated with RF as internal fixation, four patients with short Harrington rod as internal fixation. Results\ The fusion rate and clinical results of ALIF were analyzed by comparing the findings on the X-ray films taken preoperatively and 6 months postoperatively as well as by JOA score. The fusion rate of 15 segments of 14 patients(two segments of 1 patient was fused) is 85.7%, the average improvement rate of JOA score is 73.3%at an average follow up of 26.6 months. Conclusion\ ALIF with composite cortical ring could successfully restore the spinal structure, maintain the interspace height distracted intraoperatively, obtain high fusion rate and excellent clinical results.\;
