Background/aims: Surgical techniques for effective high-grade spondylolisthesis (HGS) remain controversial. This study aims to evaluate radiographic/clinical outcomes in HGS patients treated using modified Reverse Bohlman'' (RB) technique. Methods: Review of consecutive HGS patients undergoing RB at a single university-center from 2006 to 2013. Clinical, surgical, radiographic parameters collected. Results: Six patients identified: five with L5-S1 HGS with L4-L5 instability and one had an L4-5 isthmic spondylolisthesis and grade 1 L5-S1 isthmic spondylolisthesis. Two interbody graft failures and one L5-S1 pseudoarthrosis. Postoperative improvement of anterolisthesis (62.3% vs. 49.6%, p = 0.003), slip angle (10 vs. 5 degrees, p = 0.005), and lumbar lordosis (49 vs. 57.58, p = 0.049). Conclusions: RB technique for HGS recommended when addressing adjacent level instability/slip. (C) 2016 Published by Elsevier, a division of Reed Elsevier India, Pvt.
