1.What are the typical symptoms of lumbar intervertebral disc herniation? Lumbar intervertebral disc herniation occurs in L4/5 and L5/S1, typical lumbar intervertebral disc herniation symptoms are mainly manifested as lumbar pain and lower extremity radiating pain, initially there is lumbar pain or buttock pain first, and some patients aggravate and lower extremity radiating pain after a certain definite trauma, typical pain radiates from the lumbar region, buttock, posterior lateral thighs, and posterior or medial lower calves to feet, and the pain of different herniated sections is different from the radiating site. Radiation site is different. In some patients, lumbar pain can be unexplained (many patients complained of not having suffered trauma, etc.). There are also patients who only show radiating pain in the lower limbs. 2. What are the other atypical herniated discs? Other atypical symptoms of herniation can manifest differently depending on the location, size of herniation, time of compression and type of pathology, such as intermittent claudication, numbness, muscle spasm, muscle paralysis or atrophy, cauda equina syndrome resulting in urinary and defecation disorders, coldness of the limbs, caudalgia, edema of the lower limbs, and nociceptive hypersensitivity, and so on. 3, the incidence of lumbar disc herniation? According to statistics, 80% of people’s life at least once had been troubled by lumbar and leg pain, and in all the patients with lumbar and leg pain caused by lumbar disc herniation accounted for about 15%, of which 80% of the herniated parts in the L4/5 and L5/S1. 4, the relationship between disc herniation and herniation Research shows that the population over 40 years of age, found that more than 1/3 of more than at least one section of a herniated disc, but in this However, in this population, only a very small percentage of the population actually exhibit symptoms of disc herniation. It can be seen that there is no inevitable connection between herniation and herniation, herniation is a pathomorphologic change, and only the manifestation of symptoms can be called herniated disc. 5.What is the case of lumbar disc herniation requiring surgical treatment? Most of the diagnosed disc herniations are treated conservatively first, and more than 70% of the patients can be partially or completely relieved after strictly standardized conservative treatment, and only less than 30% of the patients need surgical treatment. In general, the following cases need surgery: ① Diagnosed for more than six months, after non-operative treatment is ineffective, conservative treatment for at least 6 weeks, and the symptoms worsen. ② The symptoms of lumbar disc herniation are so severe that it is hard to bear, and the patient is forced to adopt a forced position, and it is hard for the patient to move and sleep because of the pain. (iii) Single nerve palsy or cauda equina palsy, manifested by muscle paralysis or defecation and urination disorders. ④ The disease lasts for a long time, affecting normal work and life. ⑤ Huge herniated disc, estimated to be poorly treated conservatively. ⑥ Effective with non-surgical treatment, but the symptoms recur and the pain is heavier for more than 3 times, surgical treatment is recommended. ⑦ Lumbar disc herniation combined with lumbar spinal stenosis manifestation.
