OBJECTIVE: We report the clinical and radiologic difference of interbody fusion materials between autograft bones(laminar chip bones or iliac bone) and cages with pedicle screw in 360 degree fusion for various lumbar diseases. METHODS: Total 199 patients who underwent 360 degree fusion since April 1998 were analyzed. All patients have been followed more than 12 months. Postoperative clinical results were evaluated by Prolo's economic and functional scales, and radiographic fusion by Brantigan and Steffee classification. RESULTS: There were no statistical differences according to the fusion methods. But, in the radiological evaluation of 124 patients(62.3%) after 1 year, the best result was seen in using autologous iliac bone as a interbody fusion material. CONCLUSION: In the 360 degree fusion of the degenerative lumbar disease, autologous iliac bone might be the first choice with regards to the economical and fusion aspects, but factors such as operation time, amount of blood loss, and immediate postoperative pelvic discomfort should be considered.
