Acute lumbar disc herniation has an acute onset, and patients usually have a history of trauma, such as sneezing, lifting heavy objects, or even suddenly feeling severe leg pain when using the toilet, and the lower limbs are afraid to straighten because of pain, even leading to incontinence, etc. Most of them need surgery. If the patient has numbness in the perineal area, incontinence, that is, when the urine and feces can not be controlled by themselves, medical treatment of this condition is called cauda equina syndrome, and must be surgical and emergency surgery, only to remove the nucleus pulposus tissue of the prolapsed disc, will completely eliminate the compression of the cauda equina nerve, otherwise the cauda equina nerve is compressed for a longer period of time, the surgical effect is not ideal, and the situation of urinary and fecal disorders Otherwise, if the cauda equina nerve has been compressed for a longer period of time, the result of the surgery will not be very satisfactory and the urinary and fecal disorders may not be completely restored to normal. Chronic lumbar disc herniation, which is what we usually call lumbar disc herniation, is caused by degeneration of the intervertebral disc, relaxation and bulging or protrusion of the fibrous ring, mechanical compression of the lumbar nerve roots and secretion of inflammatory mediators to stimulate the nerve roots, resulting in back and leg pain. This is the most common type of patient in clinical practice, and most of these patients do not require surgery based on the degree of disc herniation. The general cause is chronic strain, improper exertion, and certain defects in the development of the lumbar intervertebral disc leading to gradual protrusion of the lumbar disc, which can generally be relieved by conservative treatment, and 80% to 90% of patients do not require surgery. If the effect of conservative treatment is not good for 3-6 months, and the symptoms are heavy or recurrent, affecting work and life, then surgery is needed, and for patients with indications for surgery, the efficacy of surgery for lumbar disc herniation is very good.
