ABSTRACT

@#Objective To explore the mechanism of percutaneous laser disc decompression (PLDD) for treating prolapse of intervertebral disc. Methods 15 rabbits were divided into 3 groups randomly: sham group, model group with PLDD treatment, model group without PLDD treatment. The nerve conduction velocity (NCV) of L6 nerve root and the activity of phospholipase A2 (PLA2) in the intervertebral disc of L5-6 were determined 2 weeks after the initial surgery. Results NCV in the group with PLDD was significantly faster than that in the group without PLDD (P<0.001); NCV in the group without PLDD was significantly lower than that in the sham group (P<0.001). The activity of PLA2 in the group with PLDD was significantly lower than that in the group without PLDD (P<0.001); The activity of PLA2 in the group without PLDD was significantly higher than that in the sham group (P<0.001). Conclusion The activity of PLA2 in the herniated discs is higher than that in normal discs, which result in NCV falls remarkably. The PLDD can reduces chemical factors such as PLA2.

ABSTRACT

Objective To study of percutaneous laser disc decompression(PLDD)in the patients of lumbar disc herniations.Methods 66 patients were treated with PLDD.The mean age of the 48 male and 18 female patients was 39.3 years old.Results 58 patients of all,or 87.9% showed excellent or good result.15 patients(78.9%)showed excellent and 2 patients(10.5%) were good,2 patients(10.6%) were fair or poor under 30 year old.15 patients(44.1%)showed excellent and 17(50.5%)patients were good,2(5.9%)patients were fair in 31~50 years old.2(15.4%) patients showed excellent and 7(53.8%)patients were good,4(29.8%)patients were fair or poor over 51 years old.Conclusion PLDD is safe and convenient method of treating lumbar disc herniations.
