summary

With the opening of the two child policy, more and more women over the age of 35 join the ranks of pregnant mothers. However, back pain is still a common phenomenon. As we all know, after the age of 35, women's body is in a downward trend, not only the incidence of fetal malformations increased, but also the complications of pregnancy increased, medically known as elderly pregnant women. Therefore, as an elderly pregnant woman, more careful pre pregnancy preparation and prenatal examination should be carried out than young mothers. As an orthopedic doctor, we often meet some anxious women in the outpatient department, just like the patient mentioned before. Today, let me share with you the cause of low back pain in the fifth month of pregnancy?.

What reason is pregnant 5 months lumbago?

First, we know that the lumbar spine is the hub of weight-bearing and activity of the human body, and the intervertebral disc is equivalent to the joint part between adjacent vertebral bodies. It is a discoid fibrocartilage tissue, which is composed of nucleus pulposus, annulus fibrosus and cartilage endplate. It is elastic and can absorb and disperse the load of the spine. With the increase of age, the degeneration of intervertebral disc aggravates, which eventually leads to the decrease of the elasticity and anti load ability of intervertebral disc. If the pressure exerted on the intervertebral disc at this time exceeds the range that the intervertebral disc can bear, it will lead to the rupture of the annulus fibrosus, the nucleus pulposus protruding backward from the breach of the annulus fibrosus, stimulating and compressing the spinal nerve, resulting in low back and leg pain with sciatica as the main manifestation.

Second: according to statistics, about 60% of women have low back pain during pregnancy. This is mainly because * with the needs of the mother and the fetus, the maternal body needs a large amount of nutrient reserves, and there is also retention of body fluids and the weight of the baby itself, which greatly increases the weight of the mothers and increases the lumbar load of the mother. In addition, the forward movement of the mother's body center of gravity leads to the increase of physiological lumbar lordosis and thoracic kyphosis, which also increases the weight bearing of the posterior supporting tissue and intervertebral disc; On the other hand, under the influence of hormones, pregnant women will have pelvic expansion, as well as the relaxation of the whole body ligament system, resulting in instability and displacement of the vertebral facet joints, and the relaxation of the posterior longitudinal ligament is more likely to make the intervertebral disc bulge and protrusion, leading to low back pain and lower limb radiation pain.

Third: it is not that the lumbocrural pain during pregnancy is related to lumbar process. The cause of lumbocrural pain during pregnancy may not be single. First of all, with the increase of hormone level, the level of relaxin increases, which leads to the relaxation of the whole body ligament and the decrease of strength, especially the sacroiliac joint capsule will become loose and thinner than normal people. When the sacroiliac joint is pulled slightly, the sacroiliac joint may be separated slightly, and when it is serious, the sacroiliac joint may be separated as much as 1cm from the joint surface! These joint ligament injuries, as well as tendon insertion injuries, can cause pain. And the obvious aggravation of pelvic anteversion, pulling the muscles around the waist, will also make the lumbar nerve compression and cause low back pain.

matters needing attention
