Conservative treatment of lumbar disc herniation, also known as non-surgical treatment, commonly used methods are: medication, braking therapy, traditional techniques, physical therapy, traction therapy, etc., as follows: 1, braking therapy: mainly bed, especially in the acute attack period, bed can make the intervertebral disc, dural sac, nerve root pressure dropped sharply, to maximize the nerve root to avoid further irritation. The bed rest here refers to absolute lying on a hard board bed, except for going to the toilet and eating all in bed. 2.Traditional techniques include tui na, massage, knee twisting, pulling, rubbing and percussion, etc. The efficacy depends on the degree of prominence and the practitioner’s technique. The mechanism is to improve microcirculation, relieve local spasm, promote inflammation absorption, change the location of the protrusion, reduce the release of inflammatory substances, improve the nerve pain threshold, and play anti-inflammatory and analgesic effects. 3.Physiotherapy: mainly electrical therapy (low-frequency, medium-frequency, high-frequency), infrared therapy, wax therapy, magnetic therapy, etc. The main role is to eliminate local muscle inflammation, relieve muscle spasm, so as to achieve analgesia and reduce the role of interdisc pressure. 4, traction therapy can be divided into mechanical traction (vibration type, pulse type, etc.), pelvic traction (continuous or intermittent), generally need to be carried out in the hospital. It is suitable for patients with short duration of disease <3 months, small protrusions <8mm and postoperative recurrence. However, it is contraindicated in patients with long duration of disease, large herniations with poor efficacy, and in those with unclear diagnosis (e.g., suspected lumbar spine tumors, tuberculosis, etc.), advanced age, poor general condition, severe respiratory and circulatory diseases, osteoporosis, spinal stenosis and aggravation after traction. The mechanism is: widening the intervertebral space, relieving muscle spasm, enlarging the intervertebral foramen, reducing the compression of nerve roots, in addition, the widened intervertebral space can tension the posterior longitudinal ligament, relax the ligamentum flavum, promote the return of the nucleus pulposus, improve the relationship between the nerve roots and the herniated disc, reduce the compression of the herniated material on the nerve roots, and achieve the purpose of treatment. Home traction for patients with lumbar disc herniation generally uses the pelvic continuous traction method, so patients need to be equipped with pelvic traction belt, traction rope, pulley fixation frame and weights, etc., and can also buy special traction clothes. The pelvic traction belt is easy to make and can be made of appropriate materials. It is better to use waxed rope with less abrasive force for the traction rope. Pulley fixing frame needs to be securely fixed on the bed frame, while traction weights can use various alternatives of suitable weight. Home traction generally uses a lighter weight, roughly controlled at about 1/10 to 1/8 of the patient's body weight. After a period of traction (about a week), if the patient's symptoms do not improve significantly, the weight can be increased appropriately. Traction generally 2 to 3 times a day, each lasting half an hour. Home traction should be carried out under the guidance of a doctor. Traction posture, weight, time, etc. should be carried out in accordance with medical advice. 2. In principle, a hard bed or other hard bed is needed to maintain the tension. Because lying on a soft bed, the role of traction is lost, and sometimes even aggravate the symptoms. 3, the traction belt used for traction must fit. The pulling force of the pelvic traction belt must act on the iliac wing and must protect the bony prominence to prevent pressure sores. 4, traction after a period of time, the symptoms may be relieved, at this time should not be prematurely suspended traction, but should continue to bed combined with traction therapy to reduce the possibility of recurrence. 5, the patient traction after a period of time if the symptoms do not improve significantly should ask the doctor to help identify the cause in a timely manner, take appropriate measures. For symptom aggravation, should immediately stop traction, ask the doctor to do further diagnosis and treatment.
