经竖脊肌、多裂肌间隙入路手术内固定治疗退变性腰腿痛的临床研究

摘要

Objective To investigate the clinical effects of fixation surgery of erector spinae,multifidus gap approach in the treatment of degenerative low back pain,in order to improve the level of clinical diagnosis and therapy. Methods 70 cases of degenerative low back pain were divided in-to control group and conservation group, each group with 35 patients. The control group was given middle posterior interbody fusion,the observation group was given fusion surgery by erector spinae, multifidus gap approach. Results There were significant differences in amount of bleeding, post-operative drainage volume, postoperative VAS score of three months, postoperative MRI signal classification of multifidus muscle (P<0.05). Conclusion Erector spinae, multifidus gap approach can reduce spine back muscle injury,accelerate recovery. The clinical effect in short-term was sat-isfactory.%目的：探讨经竖脊肌、多裂肌间隙入路手术内固定治疗退变性腰腿痛的临床效果，以便提高临床诊治水平。方法以收治的70例退变性腰腿痛疾病患者为研究对象，随机分为对照组和观察组，各35例。对照组予以后路正中椎体融合术，观察组则予以经竖脊肌、多裂肌间隙入路融合术，比较两组治疗后的临床效果。结果两组在术中出血量、术后引流量、术后3个月的VAS评分、术后多裂肌MRI信号分级上比较有明显的差异性（P<0.05），有统计学意义。结论经竖脊肌、多裂肌间隙入路融合术可减轻脊柱后部肌肉损伤，加快恢复，近期临床效果满意。
