Lumbar intervertebral disc herniation is a common and frequent clinical disease. It is a lesion mainly caused by lumbar and leg pain on the basis of intervertebral disc degeneration, stimulated or compressed by nerve roots, cauda equina nerve and blood vessels due to the rupture of the nucleus pulposus under the action of wind, cold and dampness or external forces. According to Chinese medicine, this disease belongs to the categories of “lumbago”, “lumbago and leg pain”, “lumbago and knee pain”, “paralysis” and so on. The treatment of lumbar disc herniation is usually divided into non-surgical therapy, surgical therapy and minimally invasive therapy, etc. We use non-surgical therapy such as lumbar protrusion san to treat lumbar disc herniation with good clinical effect. Clinical typing Acute phase: Patients mostly have sudden onset of lumbago with radiating pain in the lower limbs or acute onset of chronic lumbago, with severe pain, even turning over and turning to the side is difficult, and some patients may have numbness in the lower legs and feet. The examination shows interspinous or paravertebral pressure pain in the lower lumbar spine and radiating pain in the lower extremities; positive straight leg raise test, usually less than 45°, positive straight leg raise strengthening test; decreased sensation in the lateral or posterior lateral calf; decreased dorsiflexion or plantarflexion of the bunions; red or light red tongue, tight or chordal pulse; CT or MRI examination shows herniated lumbar disc nucleus pulposus, nerve root or cauda equina compression, and nerve root edema. Chronic phase: Mostly the symptoms gradually improve after treatment in the acute phase or long-term chronic pain, which is also clinically manifested as lumbar and leg pain, but can improve significantly after rest, and the symptoms worsen after exertion or walking with weight, and numbness in the calf or foot can appear. The examination shows light lumbar pressure pain, radiating pain is usually not obvious; positive straight leg raise test, usually greater than 45°, straight leg raise strengthening test is mostly negative; decreased sensation in the lateral or posterior lateral calf; decreased dorsiflexion or plantarflexion of the bunion; light red tongue with thin coating and string pulse; CT or MRI examination shows herniated nucleus pulposus of the lumbar intervertebral disc, nerve root or cauda equina compression. Treatment method Acute stage: It is advisable to promote the flow of Qi and blood, break up the accumulation and disperse the nodules, and unblock the meridians, and take Lumbar Protrusion San No.1 internally, which is composed of fried Citrus aurantium shell, Chinese Sichuan Centipede, clear scorpion, dried ground dragon, earth turtle worm and leech 30g. The above formula is finely ground and taken twice a day at 5 g. Absolute bed rest must be taken during treatment so that the ruptured fibrous ring can be repaired in a relatively static state. For those with obvious lumbar pain and pressure pain, the treatment can be combined with jointing and elimination of stasis (Anhui Provincial Hospital of Traditional Chinese Medicine in-hospital preparation) and honey to dress the lumbar area. Chronic phase: It is advisable to move qi, activate blood circulation, warm the meridians and channels, dissolve stasis and resolve coagulation, and take Lumbar Tumor San II internally. During the treatment period, avoid sitting for a long time, walk on the ground with a leather waist circumference, and strengthen the training of lumbar back muscles.
