摘要:

目的 评估腰椎后路椎间融合术(PLIF)后椎旁肌肉损伤状况。方法 前瞻性纳入接受PLIF治疗的侧隐窝型腰椎管狭窄症患者56例。记录术前、术后3个月疼痛视觉模拟评分(VAS)、Oswestry功能障碍指数(ODI);使用表面肌电图(sEMG)测定在抬物动作试验三阶段椎旁肌均方根(RMS)和中位频率(MF)变化;检测术前及术后第1、3、7天血清肌酸激酶(CK)和C-反应蛋白(CRP)水平。结果 患者术后3个月的疼痛VAS评分和ODI评分均较术前降低(P<0.05)。在测试阶段一、二中,患者术后3个月椎旁肌RMS水平低于术前,在测试阶段三中患者术后椎旁肌的MF值高于术前(P<0.05)。血清CK术后第1、3天较术前水平升高,且在术后第1天达到峰值(P<0.05),术后第7天血清CK水平基本恢复至术前水平。CRP水平术后各时点均高于术前,于术后第3天达到峰值,术后第7天较前下降(P<0.05)。结论 sEMG显示PLIF对椎旁肌组织造成了一定程度的损伤,这可能是引起患者术后椎旁肌功能下降和术后腰痛仍未完全缓解的主要原因。

Abstract:

Objective To evaluate paraspinal muscle injury after posterior midline lumbar interbody fusion. Methods Fifty-six patients with lateral recess lumbar spinal stenosis who received PLIF were prospectively included. Visual analog scale (VAS) and Oswestry Disability Index (ODI) were recorded before surgery and 3 months after surgery. Surface electromyography (sEMG) was used to measure the root mean square (RMS) and median frequency (MF) of paravertebral muscle in the three stages of lift test. Serum levels of creatine kinase (CK) and C-reactive protein (CRP) were detected before surgery and at 1, 3 and 7 days after surgery. Results The VAS score and ODI score were significantly lower in patients 3 months after surgery than those before surgery (P<0.05). In test stage 1 and 2, the level of paraspinal muscle RMS was significantly lower 3 months after surgery than that before surgery, and in test stage 3, the postoperative paraspinal muscle MF value was significantly higher than that before surgery (P<0.05). Serum CK level was significantly higher on the 1st and 3rd day after surgery than that before surgery, and which reached the peak on the 1st day after surgery (P<0.05). Serum CK level basically recovered to the preoperative level on the 7th day after surgery, and CRP level was higher at all time points after surgery than that before surgery, and reached the peak on the 3rd day after surgery, and decreased on the 7th day after surgery (P<0.05). Conclusion sEMG reveals that posterior lumbar interbody fusion causes some paraspinal muscle tissue injury, which may be the primary cause of postoperative paraspinal muscle function decline and postoperative low back pain.
