Percutaneous Laser Hypothermia in the Treatment of Lumbar Discogenic Pain / 中国微创外科杂志

ABSTRACT

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 discogenic 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 discogenic pain. The indications for the procedure should be selected strictly.
