ABSTRACT
Introduction: Low back pain is one of the most chronic debilitating conditions involving considerable loss of cash, work, and quality time. Lasers are utilized in different fields of drugs, providing unique advantages. They are useful and advantageous in treating lumbar disc disease. In this research, an attempt is made to examine the role and importance of different lasers in lumbar disc surgeries. Methods: We conducted studies about laser therapy in lumbar disc surgery. Our primary search began with reviewing English-language citations from PubMed and Scopus between 1990 and 2019 using the keywords: (laser therapy) OR (lumbar disc AND disc surgery). The initial search yielded 97 articles. However, about 49 articles were selected and used in the present study. Results: Based on the present study, it can be found that there are several methods of using lasers to treat lumbar disc surgery. These methods all have their strengths and weaknesses. Conclusion: The development of laser lumbar disc surgery can be very helpful due to the reduction of surgical risks and the length of the patients' hospital stay. However, the choice of method used for this type of surgery should be made according to the patient's condition and based on the opinion of the treating physician.
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.
