Nociception is an important self-protective mechanism of the body, which allows the body to avoid injurious stimuli due to the presence of pain. You may have heard that a child is congenitally pain deficient, that is, he does not know pain no matter what kind of stimulus he receives. Some people say that it is good not to know pain! Because pain is so painful! Not to mention that toothache is a small thing, but the pain is also deadly! But what would happen if you really don’t know the pain? Let’s see what life is like for people who don’t feel pain. People without pain sensation, cutting vegetables accidentally hand cut by the knife, because do not know the pain, cut a little do not know to dodge the results cut a large mouth, and even injured the tendons blood vessels; with hands to end the pot, if the pot is very hot, the hand touched no feeling, the results of scalding blisters; and, accidentally hand stabbed by a needle, because no feeling do not know to retract and dodge, the results of the needle into the body …… There are many more cases that can be told like this. People with congenital pain loss generally have a short life span because they don’t know how to avoid danger and injury. Pain is very important to humans, but pain is also really very torturous ah! Today I will talk about low back pain. Low back pain as a condition has a very high prevalence in the population. Let’s think back to ourselves, children dare not say, adults must have experienced more or less severe low back pain. Two days ago, a close classmate of mine, a 41-year-old strong man on a business trip suddenly had back pain, very intense, to what extent? He went to the hospital and his companion carried him on his back, there was no way to walk! For the elderly, low back pain is more common, and even some elderly people are actually hidden low back pain in the insistence of living, if one day low back pain can be a little lighter, that is simply a great good thing! If you like to be serious, you can consult your grandparents and ask them if they often have low back pain. Any symptom has a cause, and low back pain is no exception. The common causes of low back pain are: lumbar strain, lumbar sprain, lumbar back fasciitis, lumbar spine small shutdown disorder, lumbar disc herniation, lumbar spine slippage, lumbar spine tuberculosis, lumbar spine tumor …… I will not enumerate more. But for the elderly, there is a cause that is very common but easily overlooked and neglected. For elderly people who have frequent back pain, we must be careful of a disease that is quietly affecting their lives – crestal compression fracture. When it comes to fractures, the first thing that comes to mind is a broken arm or leg in a car accident, or a broken ankle bone in a soccer game. But the elderly do not have these things, that is, buy vegetables, walk a corner, water the flowers …… This is not connected to injury! How is it possible to break a bone? Don’t worry, this is the characteristic of a crestal compression fracture. Crestal compression fractures are the most common type of osteoporotic fragility fracture. According to the WHO standard 65 years old and above is called the elderly, into old age, the body’s functions are gradually aging and weakening, manifested in the skeleton is the first is quietly occurring osteoporosis. We all know that people need to take calcium supplements when they are old, that is, in the treatment of osteoporosis. Of course, osteoporosis is not just a simple lack of calcium. Simply put, osteoporosis means that the bones are not strong enough to withstand the load. When osteoporosis is so severe that it cannot withstand fluctuations in load, it can still cause damage to the vertebrae of the crest, even though the fluctuations are small. For example, there is an old man who once watered the flowers, the bucket was filled with a little more water, and when carrying the bucket, he felt his waist “flash”, resulting in severe back pain, and at first he thought it was a lumbar muscle strain, and he would be fine in a few days, but in the past month there was no sign of improvement, so he went to the hospital to take an X-ray and found out that the crestal vertebrae were fractured. The fracture of the vertebral body of the crest Of course, a crestal compression fracture is indeed different from a fracture, which is more insidious. The human crest is made up of 33 vertebrae in series, and the main part of each vertebra is like a cylinder, which looks like a square from the side projection. Because of this, such fractures are ignored by patients and even some doctors who are not experienced enough. The good thing is that medicine is evolving and doctors have some weapons in their hands to alert the elderly to this condition and also to effectively detect and prove compression fractures. The first is the bone density test, which so many people are familiar with or even have checked. If, for example, your bone density is low and your doctor has told you that you have low bone mass or osteoporosis, be very careful and once you have low back pain, especially if it does not get better for a long time, be more careful and find a crest surgeon to look at it is always necessary. The second is a crestal X-ray, which shows the shape of the bones and whether the vertebrae have been “flattened”. The third is magnetic resonance imaging, or MRI for short. Sometimes an x-ray can only show changes in the shape of the vertebral body, but it is not known whether the changes are new or previous, so MRI can come in handy. If you have an elderly person around you who always has low back pain, have that person see an orthopedic surgeon to receive the necessary tests and treatment. This is because crestal osteoporotic fractures, if left untreated, can continue to develop and change, sometimes to the point of requiring major surgery.
