Abstract
- PURPOSE
To evaluate the long-term results of an anterior lumbar interbody fusion with posterior instrumentation using a single autogenous tricortical iliac graft, and to identify factors affecting results. MATERIALS AND METHODS: This study included 91 patients, 117 levels underwent anterior lumbar interbody fusion with posterior instrumentation. Radiological and clinical results were evaluated and factors affecting the results were analyzed. RESULTS: An average area of the graft was 213.3 mm2; 20.2% of the contacting end-plate. Ninety-two percent of levels obtained bony fusion and 87% of patients showed excellent or good clinical results. Compensation status was a significant prognostic factor. Patient's age, sex and graft size showed no significant relationship with the results. CONCLUSION: Our data suggest that a single block of autogenous tricortical iliac bone is sufficient for acceptable results in cases of anterior lumbar interbody fusion combined with posterior instrumentation.
