The clinical and radiographic results of lumbar isthmic spondylolisthesis were compared between interspinous block-assisted anterior interbody fusion (block-assist group, n = 16) and anterior interbody fusion with no use of the block (nonassist group, n = 17) with an average follow-up of 7 years (range 1 1/3-13 years). Satisfactory relief of low-back pain, significantly early interbody union (union rate 88%, p < 0.05), and spontaneous fusion of pars defect (fusion rate 44%, p < 0.05) were obtained in the block-assist group. In the nonassist group, interbody union was markedly delayed (p < 0.05), the union rate was 53%, and spontaneous fusion of the pars was found in 12% of patients. The overall clinical results at final follow-up in both groups did not show a statistically significant difference, but the results tended to be superior in the block-assist group.
对平均随访7年（范围为1又1/3 - 13年）的棘突间阻滞辅助前路椎间融合术（阻滞辅助组，n = 16）和未使用阻滞的前路椎间融合术（非辅助组，n = 17）治疗腰椎峡部裂性脊椎滑脱的临床和影像学结果进行了比较。阻滞辅助组获得了满意的腰痛缓解、显著更早的椎间融合（融合率88%，p < 0.05）以及椎弓根缺损的自发融合（融合率44%，p < 0.05）。在非辅助组中，椎间融合明显延迟（p < 0.05），融合率为53%，12%的患者出现椎弓根自发融合。两组最终随访时的总体临床结果无统计学显著差异，但阻滞辅助组的结果有更优的趋势。
