The commonly used method to treat lumbar disc herniation is: 1. Relieve muscle spasm of waist and buttocks: the patient is prone. Doctors treat patients' waist, buttocks and lower limbs with gentle rolling pressing, which can accelerate the blood circulation of the affected part, accelerate the absorption of water in the protruding nucleus pulposus, reduce its oppression on nerve roots, and relax the tense and spasmodic muscles. 2. Widen the intervertebral space and reduce the pressure on the intervertebral disc: the patient takes the supine position. Doctors use manual or mechanical pelvic traction to widen the intervertebral space, reduce the pressure or even negative pressure on the intervertebral disc, promote the reduction of the protrusion, enlarge the intervertebral foramen and nerve root canal, and reduce the pressure of the protrusion on the nerve root. 3. Increase the pressure outside the intervertebral disc: the patient is prone. Doctors press the waist rhythmically with both hands to make it vibrate, and then under the condition of fixing the affected part, the waist is overstretched by stretching the lower limbs backwards, in order to promote the retraction of the protrusion or change the position of the protrusion and the nerve root. 4. Adjust the posterior joint and release the adhesion: The doctor adjusted the disorder of the posterior joint by means of lumbar oblique pulling or rotational reduction, so that the nerve root canal and intervertebral foramen were relatively enlarged. Because the lumbar spine and its intervertebral disc produce rotational torque during oblique traction and rotational reduction, the positions of the processes and nerve roots change. After repeated application, the adhesion between the process and the nerve root can be gradually relieved. In supine position, pulling the sciatic nerve and hamstring muscle with straight legs can play a certain role in releasing adhesion. 5. Promote the recovery of damaged nerve roots: the patient is prone. Doctors use methods such as rolling, pressing, pressing, kneading and banding to accelerate the circulation of qi and blood along the damaged nerve roots and their distribution areas, so that atrophied muscles and paralyzed nerves gradually return to normal functions.
