The same is true for intervertebral discs. Why is ''you'' the most prominent?


The structure of the human spine is very complex, with a total of 24 vertebrae for the adult spine. Due to the absence of intervertebral discs between the sacrum and the vertebrae, there are only 23 discs in the body. They are located between two vertebral bodies. The total thickness of the disc was l/4-1/5 of the total length of the spine. The lumbar intervertebral disc is the thickest, about 9 mm. There is a lumbar intervertebral disc between the lumbar 1 and the sacrum. People often say that the disc herniation actually refers to the herniation of the lumbar intervertebral disc. In fact, there are intervertebral discs between the cervical and thoracic vertebrae. It also stands out, but the symptoms and signs, and the treatment methods are different. The intervertebral disc is located between two vertebral bodies and is a structure with hydrodynamic characteristics. It consists of three parts: nucleus pulposus, annulus fibrosus, and cartilage plate.

Clinical symptoms of lumbar disc herniation According to the location, size and size of the vertebral canal sagittal diameter, pathological features, body state and individual sensitivity, the clinical symptoms can vary widely. Therefore, we must have a thorough understanding of the common symptoms of the disease. 


Back pain: More than 95% of patients with lumbar intervertebral disc protrusion (dislodgement) have this symptom, including vertebral body type.

Clinical manifestations: persistent dull back pain is more common, supine position is reduced, standing is intensified, under normal circumstances can be tolerated, and allow the waist to moderate activities and walk slowly, mainly due to mechanical oppression. The duration is as little as 2 weeks, and the elderly can reach months or even years. The other type of pain is a kind of severe pain at the waist. Not only is the sudden onset and abruptness of the disease, but it is unbearable. Non-bed rest is not allowed.


Lower limb radiating pain: This disease occurs in more than 80% of cases, among which the latter type can reach 95% or more.

Clinical manifestations: Light manifested as radioactive tingling or numbness from the waist to the thigh and back of the calf, reaching to the sole of the foot; generally tolerable. In severe cases, electric shocks from the waist to the foot are severe, and many are accompanied by numbness. Although the pain is still light, but the gait is unstable, showing a lame line; severe cases are bed rest, and hi to take hip flexion, knee flexion, lateral position. All factors that increase abdominal pressure increase radiating pain.



Extremity numbness: more associated with the former, only numbness without pain is only about 5%. This is mainly due to stimulation of proprioceptive and tactile fibers in the spinal nerve roots. Its extent and location depend on the number of affected nerve root sequences.



Cold limb sensation: A few cases (about 5% to 10%) consciously chill and cool, mainly due to stimulation of sympathetic nerve fibers in the spinal canal. It is often the case that the patient complains of a limb fever on the day after surgery. This is the same mechanism.


Intermittent claudication: Its production mechanism and clinical manifestations are similar to those of lumbar spinal stenosis, mainly because of the pathological and physiological basis of secondary lumbar spinal stenosis in the case of prominent nucleus pulposus; In patients with narrow sagittal diameter of the developmental spinal canal, prolapsed nucleus pulposus severely stenosis of the spinal canal, so as to induce this symptom easily.



Muscle paralysis: The paralysis of lumbar intervertebral disc herniation (desitosis) is very rare, and many of the paralysis syndromes caused by the damage to the roots caused by different levels of muscle control. Light muscle strength is weakened, and in severe cases the muscle loses its function.


Horsetail nerve symptoms: mainly found in the posterior central and paracentral nucleus pulposus (dislocation) out of the disease, so clinically rare. Its main manifestations are perineal numbness, tingling, defecation and urination disorders, impotence (male), and lower limb sciatic nerve involvement. In severe cases, there may be symptoms such as uncontrolled urine and incomplete paralysis of the lower extremities.


Lower abdominal pain or anterior thigh pain: In the high lumbar disc herniation, when the nerve roots of the lumbar 2, 3, and 4 are involved, there is pain in the inguinal region of the lower abdomen or inner thigh of the thigh, which is mostly pain. Involved in pain.


The skin temperature of the affected limb is lower: it is similar to the cold feeling in the limbs, but also due to pain in the affected limbs, especially in the toes. The phenomenon of skin temperature decrease is more pronounced in those who have received compression of the nerve roots of the ulnar nerve than those who have received nerve compression from the lumbar 5 nerve root. Conversely, after removal of the nucleus pulposus, the limb feels feverish.


Others: depending on the compression of spinal nerve roots and the degree of compression, the extent of involvement of adjacent tissues, and other factors, some rare symptoms may occur, such as excessive sweating, swelling of the limbs, sacrococcygeal pain, and radiating pain in the knee.
