P105. Comparison of Radiographic Fusion Rates Between One Level and Two Level Stand-Alone ALIFs

Abstract

BACKGROUND CONTEXT: One level stand-alone anterior lumbar interbody fusions (ALIF) have been shown to be successful in treating discogenic pain. This procedure results in acceptable fusion rates (Sasso et al., Spine 2004). There is little data on two level ALIF without posterior stabilization. Kuslich et al. (Spine, 1988) reported on ALIFs and showed a 92% success rate for one level versus 78% for two level. We are not aware of other studies which compare the fusion rate of one versus two levels.
