Bone-setting is the most convenient, effective and fastest green conservative therapy for the treatment of disc herniation. Chen's bone-setting is a unique bone-setting technique applied to the intervertebral space of the affected part, which stretches the posterior longitudinal ligament and increases the negative pressure in the intervertebral space. At this time, the physical effect of suction is generated and enhanced, so that the prominent nucleus pulposus can be degraded and restored, and the compression of nerve roots can be alleviated. At the same time of negative pressure, the blood flow around the intervertebral disc accelerates and inflammatory substances are absorbed by the body. Stimulated by external force, Shu point produces a strong sense of qi, which can dredge meridians, promote blood circulation and remove blood stasis, thus improving a series of symptoms caused by protrusion. It not only eliminated the superficial symptoms, but also eradicated the causes, achieving the effect of treating both the symptoms and the root causes.
