ABSTRACT
OBJECTIVE
The purpose of this study is to analyze clinical outcome of lumbar spinal fusion with autobone graft and with allobone graft as an additional autograft extender. METHODS: Fifty two patients who underwent lumbar posterolateral arthrodesis for degenerative lumbar diseases between February, 1998 and October, 2000 were evaluated. Arthrodesis was performed by transpedicular screw fixation. We used autogenous bone graft in 32 cases (Group A) and allobone graft in 20 cases (group B). Post operative radiographs were obtained to review the resorption of graft bone and the evidence of fusion. A modified Lenke scale was used to assess the status of the fusion. RESULTS: There were 17 men and 35 women. Mean follow up period was 12 months. According to the modified Lenke scale, spinal bone fusion rate was 93.75% in the group A and 85% in the groub B. CONCLUSION: Lumbar spinal fusion using allobone graft is favorably good compare to autobone graft.
Key Words: Autogenous bone graft; Allobone graft; Spinal fusion; Transpedicular screw; Degenerative lumbar disease
