The key to the pathogenesis of cervical and lumbar intervertebral disc herniation is spinal instability. Three-dimensional computer traction orthopedic therapy is to use the mechanics principle to imitate the traditional medical techniques of oblique wrenching, rotational reset, traction and other techniques, so that the angle, rotation and traction are completed at the same time to promote the change of the three-dimensional direction between the diseased vertebrae, so as to restore the physiological curvature, correct the uneven force on the intervertebral disc, and generate negative pressure on the intervertebral disc to promote the retraction of the herniated object, achieve a new balance of the three-dimensional structure between the vertebrae, and reduce and eliminate the irritation and compression on the It can reduce and eliminate the stimulation and compression of nerve roots. Three-dimensional traction is one of the effective measures for the treatment of cervical and lumbar herniation and is a commonly used treatment method in clinical practice. The mechanism of action is: (1) to restore the normal position of the intervertebral joints of the cervical and lumbar spine, which is conducive to the decreasing of tissue congestion and edema. (2) Release the muscle spasm of the cervical and lumbar region and relieve pain. (3) Enlarging the vertebral space and intervertebral foramen, and releasing the protrusion from the nerve root, vertebral artery, spinal cord and other compression. (4) To distract the embedded synovial membrane of small joints. (5) Reduce the local inflammatory reaction of the protrusion. Due to the stimulation and compression of the protrusion, local edema, congestion, exudation, etc. can be produced, resulting in painful symptoms, and the fixation and braking effect produced by traction can make it subside more rapidly, thus relieving the symptoms Indications: Three-dimensional computer traction can be used to treat mild to moderate lumbar disc herniation, but also lumbar small joint dysfunction, early ankylosing spondylitis, chronic low back pain caused by degeneration, and chronic lumbar sprain, acute sprain and chronic injury of the lumbar region, and lumbar muscle fibrous tissue inflammation.
