The incidence of lumbar disc herniation in mainland China is about 18%, and it is also getting younger at an alarming rate, and among patients aged 20-40, more than 60% of patients with lumbar disc herniation are about 60%.
The pressure of modern people's life continues to increase, and long-term sitting at high intensity work also leads to people's joints not being stretched, and there will be more and more problems with physical functions.
High incidence of lumbar disc herniation, or inseparable from these 5 common factors, are you close to them
1. Age
With age, the intervertebral disc will gradually degenerate, the water content of the fibrous ring and nucleus pulposus will gradually decrease, the nucleus pulposus will lose its elasticity, and the fibrous ring will gradually appear cracked.
On the basis of degeneration, the accumulation of strain and the action of external forces, the intervertebral disc ruptures, the nucleus pulposus, fibrous ring and even the endplate protrude backwards, and severe patients will compress the nerves, and then a series of symptoms will appear.
2. Injury
Long-term accumulated injury is also a major factor in lumbar disc degeneration. For example, daily life needs to repeatedly bend over, twist the waist, etc., these actions can easily cause intervertebral disc damage.
3. Excessive weight bearing
Many patients with lumbar disc herniation are manual workers, because excessive weight bearing can also lead to lumbar herniation. Studies have found that normal people are prone to lumbar herniation if they bear more than 100kg.
Long-term weight bearing can easily lead to narrowing of the intervertebral discs, increased pressure, and lateral protrusion.
4. Smoke
Studies have found that nicotine in tobacco can cause vasoconstriction, so that the blood supply of the lumbar intervertebral disc will also be reduced, and it is easy to undergo degenerative changes, so people who smoke for a long time are prone to lumbar disc herniation.
5. Sitting for a long time and getting cold
Now many jobs also require long-term sedentary, and there are many cases of lumbar herniation in sedentary people. Because of long-term desk work and frequent exercise, the lumbar spine needs to support the weight of the upper body all the time, so that the lumbar spine is squeezed by gravity for a long time, and it is easy to degenerate or cause damage to surrounding tissues.
Or some people are in a humid and cold environment for a long time, and the lumbar spine is easy to protrude. Because cold and humid places can easily cause small blood vessels to constrict and muscle spasm, resulting in increased pressure in the lumbar spine, the lumbar spine is prone to protrusion, or the intervertebral discs are easy to rupture.
One teaches you to tell if you have a herniated lumbar disc
Straight leg elevation experiments can be done. The patient can lie on both lower limbs or even on the bed, allowing the family to support the back of one ankle with one hand and the other hand to press the front of the knee, and slowly lift the lower limb with the hand that supports the ankle while keeping the knee straight.
Until the patient feels radiation pain in the lower extremities and the examiner feels significant resistance, the angle formed between the lower limbs and the bed is the straight leg height.
Normal people can raise about 90 degrees and will not feel pain. If the lift is less than 70 degrees, the patient has electric shock pain or low back pain, generally there may be a lumbar disc herniation, it is recommended to go to the hospital for further diagnosis.
