Curative effect observation on treatment of moderate-to-severe isthmic spondylolisthe-sis with sufficient decompression to distract intervertebral space for spondylolisthesis reduction and interforaminal fusion internal fixation
Objective To observe the feasibility and clinical effect of space extension under sufficient decompression,spondy-lolisthesis reduction and through interforaminal fusion and internal fixation for the treatment of moderate-to-severe isthmic spondylolisthesis.Methods Twenty-seven patients with moderate-to-severe isthmic spondylolisthesis were retrospectively analyzed,who were diagnosed and treated with sufficient decompression to distract intervertebral space for spondylolisthesis reduction and interforaminal fusion internal fixation from January 2014 to June 2021.The low back pain VAS scores preopera-tively and 2 weeks postoperatively were compared as well as ODI indices preoperatively and 6 months postoperatively.Re-sults The operation time in this group ranged from 180 to 245 min,with an average of 223.2 min;intraoperative bleeding ranged from 100 to 250 mL,with an average of 110.0 mL.Follow-up was obtained in all 27 cases and ranged from 9 to 16 months,with a mean of 11.2 months.There were no complications such as deep incision infection,internal fixation loosening,or vertebral re-slip during the follow-up period.The time of interbody fusion ranged from 8 to 14 months,with a mean of 9.9 months.The VAS score for low back pain at 2 weeks postoperatively was(1.70±0.46),which was significantly lower than that preoperatively(5.00±1.03),and the difference was statistically significant(t=5.210,P＜0.001).The ODI index at 6 months post-operatively was(19.90±3.41)％,which was significantly lower than that preoperatively(53.93±5.89)％,and the difference was statistically significant(t=12.750,P＜0.001).Conclusion The treatment of moderate-to-severe isthmic spondylolisthesis with sufficient decompression to distract intervertebral space for spondylolisthesis reduction and interforaminal fusion internal fixa-tion can achieve satisfactory efficacy,ensure surgical safety while obtaining anatomical repositioning and fusion,and have a low incidence of postoperative complications.
