Efficacy And Mechanism Of Nonoperative Spinal Decompression In Treatment Of Lumbar Disc Herniation

Objective To observe the efficacy of non-operative spinal decompression system(SDS9800)in the treatment of lumbar disc herniation,and to explore the mechanism of its clinical curative effect from the aspects of symptoms,signs and images,and to provide the basis for the rational selection of treatment methods.Methods Selecting 40 LDH patients accord with the experimental requirements,then we divided them into the treatment group and control group,with 20 cases in each group,both of the groups were given the same conventional treatments,the former was given non-surgical spinal decompression treatment as well and the latter given ordinary lumbar traction treatment,each group was treated for 4 weeks,with 6 times every week.Before treatments,we recorded the pain visual analogue scale(VAS)and angle of straight leg rising(ASLR)of each patient,the transverse and sagittal scans of the lumbar magnetic resonance were performed,and used the medical image browser software(Radiant DICOM Viewer 4.0.3)to measure the area of the disc herniation in the spinal and the angel between prominence and nerve root(AN)from the transverse scans;at the time when the four-week treatments of each group were finished,we recorded the parameters above again to observe the efficacy of the two treatment methods from the aspects of symptoms,signs and images.At the end of the related data were analyzed and summarized by statistical software spss.17.0.Results By statistical analysis showed,general situation of the two groups were no obvious differences.Before treatment,the treatment group VAS score was 5.40±1.10,ASLR was 42.25±7.86,the area of the disc herniation in the spinal was 96.27±16.99,AN was 25.56±3.35;the control group VAS was 5.60±0.99,ASLR was 40.50±7.42,the area of the disc herniation in the spinal was 95.78±17.04,AN was 24.42±2.97;There was no significant difference in VAS,SLR,protrusion area and AN value between the two groups before treatments;After treatment,the treatment group VAS score was 2.05±0.89,ASLR was 72.00±5.23,the area of the disc herniation in the spinal was 96.43±17.00,AN was 29.07±2.17;the control group VAS was 2.65±0.93,ASLR was 68.75±4.55,the area of the disc herniation in the spinal was95.7±17.11,AN was 26.93±3.61;compared with pretherapy,the VAS of the two groups decreased,the SLR significantly increased and the AN values increased in the both groups after treatment,all above were significantly different(P<0.05),further more,all measured results above of the treatment group changed more significantly;but the protrusion area did not change after treatment of both groups,it had no significant difference during both groups(P>0.05).Conclusions Both non-operative spinal decompression and general traction were effective in the treatment of LDH,but the former was more obvious.Combined with the authors' follow-up,there were no long-term adverse reactions.Therefore,so the non-operative decompression treatment system was worth popularizing.And the important mechanism of SDS in treating lumbar disc herniation maybe changing the position relationship between herniated intervertebral disc and nerve root,which is not completely related to the size of protrusion.
