激光低温理疗治疗椎间盘源性腰痛

目的探讨激光低温理疗治疗椎间盘源性腰痛的临床疗效。方法2006年6月～2008年3月,应用低功率激光低温理疗治疗椎间盘源性腰痛35例,采用低功率激光,按脉冲时间1s,间隔时间1s的标准,功率3.5W,持续时间30min的标准治疗,术前和术后对患者进行治疗效果评价。结果15例行1次手术,14例行2次手术,6例行3次手术。最终疗效为32例有效（其中7例优,24例良,1例可）,2例无效,1例因效果不佳行开放手术治疗,有效率达91.4%（32/35）,优良率88.6%（31/35）。结论严格选择适应证,低功率激光低温理疗治疗椎间盘源性腰痛具有确切的疗效。

Percutaneous Laser Hypothermia in the Treatment of Lumbar Discogenic Pain

Objective To evaluate the efficacy of percutaneous laser hypothermia in the treatment of lumbar discogenic pain. Methods From June 2006 to March 2008, 35 patients with lumbar discogenie pain were treated by low-frequency laser hypothermia in our hospital with 1 second impulse time, 1 second interval time, 3. 5 w power, and 30 minutes duration. The effectiveness of the therapy was evaluated afterwards. Results Among the cases, 15 patients were treated by one operation, 20 patients received a second therapy, and 6 underwent the therapy for totally 3 time ; the treatment was effective in 32 cases （ excellent in 7, good in 24, and fair in 1 ）. The therapy is ineffective in 2 cases. One case was converted to open surgery for unsatisfying outcomes of the laser hypothermia. The total effective rate was 91.4% （32/35） , and fineness rate was 88.6% （31/35）. Conclusions Percutaneous laser hypothermia is an effective treatment for lumbar discogeuie pain. The indications for the procedure should be selected strictly.
