We treated 32 patients with low-grade (<30%) isthmic spondylolisthesis at L5-S1 with selective instrumentation, reduction of the slip, resection of the pseudoarthrosis adding autologous bone grafting and decompressing the root canal. The ages ranged from 18 to 54 years. After a mean of 3.4 (1-7) years, we found good radiological and clinical results in 27 patients. Five patients lost correction, of whom three were asymptomatic whereas two required fusion of L5-S1. We think this technique is a useful surgical option for select patients.
我们采用选择性内固定、滑脱复位、假关节切除并植骨及根管减压的方法治疗了32例L5-S1节段低度(<30%)峡部裂性椎体滑脱患者。患者年龄在18至54岁之间。平均随访3.4(1 - 7)年后,我们发现27例患者获得了良好的影像学和临床效果。5例患者矫正丢失,其中3例无症状,2例需要行L5-S1融合术。我们认为该技术对于特定患者是一种有效的手术选择。
