【摘要】：目的研究腰椎前凸角度和腰椎活动度与马尾神经根松弛症(RNRs)发生的相关性。方法回顾性分析自2007-01—2013-12行腰椎后路椎板全切减压手术的93例腰椎管狭窄症,依据磁共振T2序列腰椎椎管内迂曲团状的信号影,分成马尾神经根松弛组(RNRs组)和非马尾神经根松弛组(NRNRs组)。比较2组JOA评分和改善率,背伸位、屈曲位、中立位腰椎前凸角及腰椎活动度。结果 93例均获得平均17.4(12~26)个月随访。NRNRs组术后JOA评分及改善率均高于RNRs组,差异有统计学意义(P0.05)。2组屈曲位腰椎前凸角差异无统计学意义(P0.05)。RNRs组中立位和背伸位腰椎前凸角及腰椎活动度大于NRNRs组,差异有统计学意义(P0.05)。结论因为RNRs可能产生了一些不可逆损伤,所以合并RNRs的腰椎管狭窄患者手术疗效较差。腰椎前凸角度和腰椎活动度的改变是导致RNRs的2个因素。
[Abstract]:Objective to study the correlation between lumbar anterior kyphosis angle and lumbar motion and the occurrence of cauda equina nerve root relaxation. Methods 93 cases of lumbar spinal stenosis underwent posterior laminectomy decompression from January to December 2007 were retrospectively analyzed. According to the signal intensity of the lumbar spinal canal in T2 sequence, they were divided into cauda equina nerve root relaxation group and non-cauda equina root relaxation group. The JOA score and improvement rate, dorsal extension position and flexion position were compared between the two groups. Results the mean JOA score and improvement rate of 93 cases were higher than that of RNRs group. There was no significant difference in lumbar kyphosis angle in flexion position in P0.05n.2 group. There was no significant difference in lumbar kyphosis angle and lumbar motion in neutral position and dorsiflexion position. The range of motion of lumbar vertebrae in NRNRs group was higher than that in NRNRs group. Conclusion because RNRs may produce some irreversible damage, the surgical effect of lumbar spinal stenosis complicated with RNRs is poor. The changes of lumbar kyphosis angle and lumbar mobility are two factors leading to RNRs.
