扳牵疗法治疗腰椎间盘突出症的机理

The mechanism of pulling-extending therapy for protrusion of lumbar intervertebral disk

对采用扳牵疗法治疗的５２例腰椎间盘突出症患者治疗前后的Ｘ线与ＣＴ检查结果进行对比观察。结果显示，治疗后腰椎曲度、椎后关节紊乱显著改善（Ｐ＜０．０１）；突出物消失１２例，减小１６例，与受压神经根分离２４例。表明扳牵疗法能增加脊柱稳定性，可使突出物不同程度回纳，改善突出物与神经根之间的位置关系。

Fifty-two cases of protrusion of lumbar intervertebral disk were treated by pulling-extending therapy (PET), and the results of x-ray and CT examinations before and after treatment were observed and compared. The results showed post-therapeutic significant improvement in lumbar rachiocampsis and posterior-facet-joint derangment (p<0.01); protruded-mass disappearance in 12 cases and shrinkage in 16; no change (but separated from the compressed nerve-root) in 24 after treatment. It was indicated that by PET spinal stability was increased, the protruded mass was returned in various degrees, the position relation between the protruded mass and the compressed nerve-root was improved, and thereby the therapeutic aim could be achieved.
