微创单侧椎弓根螺钉固定、椎体间融合治疗腰椎疾患所致腰痛的临床观察

目的:评价微创单侧椎弓根螺钉固定、椎间融合治疗腰椎疾患所致腰痛的临床疗效。方法:2003年12月～2006年8月,共收治不同原因所致腰痛患者29例,其中腰椎间盘突出症13例,腰椎不稳8例,椎间盘源性腰痛5例,MED术后复发3例,均采用可扩张管道系统经椎间孔行椎体间植骨融合、单侧椎弓根螺钉固定术治疗。应用视觉模拟评分系统(VAS)评估患者术前、术后疼痛情况,应用Kim方法评价临床效果,应用Schulte方法观察植骨融合情况。结果:1例患者术后出现对侧下肢放射性疼痛,保守治疗无效,再次手术行神经根管减压和内固定后症状缓解。随访21～36个月,平均31.5个月,术前VAS评分为7.7±0.6分,术后3个月时为1.9±0.9分,两者比较有显著性差异(P0.001),术后3个月时Kim优良率为89.7%,末次随访时Kim优良率为96.6%,满意率为96.6%。末次随访时椎间融合率为93.1%,1例可能融合和1例假关节形成。结论:微创单侧椎弓根螺钉固定是治疗腰痛的一种有效方法,但需要严格把握手术适应证。

Minimally invasive unilateral pedicle screw fixation and transforaminal lumbar interbody fusion for low back pain

Objective:To investigate the clinical outcome of unilateral pedicle screw fixation and transforaminal lumbar interbody fusion for low back pain.Method:Between December 2003 and August 2006,a consecutive of 29 patients(13 lumbar disc herniation,8 lumbar instability,5 discogenic low back pain and 3 recurrent lumbar disc herniation after microendoscopic surgery) presenting with low back pain were performed with unilateral pedicle screw fixation and transforaminal lumbar interbody fusion.VAS score system was us...
