ObjectiveTo observe the clinical effect of orthopaedicspinal technique of lumbar vertebra fixed point fine adjustment combined with point injection for lumbar disc herniation and its effect on the immune level.MethodsDivided 130 cases of patients with lumbar disc herniation into the treatment group and the control group randomly，65 cases in each group.The treatment group receivedorthopaedicspinal technique of lumbar vertebra fixed point fine adjustment combined with point injection for treatment，while the control group received ibuprofen tablets orally combined with lumbar electric traction.Observed patients in both groups before and after treatment according to the criterion of curative effect of low back pain of Japanese Orthopedic Association(JOA).Analyzed IgG，IgM and IgA in both groups before and after treatment.Objectively evaluated the clinical effect of orthopaedicspinal technique of lumbar vertebra fixed point fine adjustment combined with point injection for lumbar disc herniation and its effect on the immune level.ResultsNo significant difference was found in the comparison of the total effective rate between the two groups(P＞0.05)，but the clinical control rate and the obvious effective rate in the treatment group were higher than those in the control group，differences being significant(P＜0.05).The respective comparisons of IgG and IgM before and after treatment between the two groups showed significance in differences(P＜0.05).No significant difference was found in the comparison of IgA content before and after treatment between the two groups(P＞0.05).The comparison of content differences of IgG and IgM between the two groups showed significance in differences(P＜0.05，P＜0.01).No significant difference was found in the comparison of the change of IgA content between the two groups(P＞0.05).ConclusionThe therapy of orthopaedicspinal technique of lumbar vertebra fixed point fine adjustment combined with point injection for lumbar disc herniation has exact curative effect，which can relieve immune response of surrounding tissues of herniated disc and pain of patients.
