骶管注射对无坐骨神经痛性腰椎间盘突出症的疗效分析

目的：观察骶管注射疗法对无坐骨神经痛性腰椎间盘突出症患者的疗效。方法：2010年12月至2011年6月，对就诊的65例经CT或MRI检查证实为腰椎间盘突出或膨出所致的急性腰痛且无下肢放射痛的患者随机分为骶管注射组（试验组）和腰椎斜扳组（对照组），试验组35例，男30例，女5例，年龄3356岁，平均（43．90±1．14）岁；对照组30例，男27例，女3例，年龄3457岁，平均（44．00±1．19）岁。两组的发病时间为1 h～3 d。分别行骶管注射或腰椎斜扳手法治疗。比较治疗前和治疗后30 min两组的VAS评分。结果：所有患者经治疗后急性腰痛症状明显缓解，骶管注射组和腰椎斜扳组的VAS评分分别从（6．63±0．97）和（6．67±0．96）分减至（3．06±1．51）和（3．93±1．20）分，两种治疗方法均能改善患者VAS评分，但骶管注射组治疗要优于腰椎斜板组（P 0．05）。结论：骶管注射和腰椎斜扳疗法对无坐骨神经痛性腰椎间盘突出症急性腰痛的患者具有快速缓解的作用，且前者的疗效更佳。

Efficacy analysis of sacral canal injection in patients with lumbar disc herniation associated with non-sciatica

Objective: To observe the outcome after sacral canal injection in patients with disc herniation associated with without sciatica. Methods: From December 2010 to June 2011,65 patients with acute low back pain without sciatica due to lumbar disc herniation or bulging confirmed by CT or MRI were randomly divided into sacral canal injection group (experimental group) and lumbar oblique wrench group (control group):the experimental group had 35 cases,including 30 males and 5 females,with an average age of (43.90±1.14) years old ranging from 33 to 56 years old. The control group had 30 cases,including 27 males and 3 females,with an average age of (44.00±1.19) years old ranging from 34 to 57 years old. The course of morbidity was 1 to 3 days. All patients received sacral canal injection or lumbar oblique wrench method. The visual analog scale (VAS) scores before and at 30 min after treatment were compared between two groups. Results: The symptom of acute low back pain were relieved obviously. The average VAS scores before and after treatment in experimental group were decreased from 6.63±0.97 to 3.06±1.51,in control group were from 6.67±0.96 to 3.93±1.20 respectively. These two methods could improve the VAS score,but the effect of sacral canal injection group was better than that of lumbar oblique wrench group,there was statistically differences(P<0.05). Conclusion: It is effective that the methods of sacral canal injection and lumbar oblique wrench applied to patients with acute low back pain without sciatica due to lumbar disc herniation or bulging confirmed,the former has better effect.
