Causes of intervertebral hernias
The main cause of intervertebral hernias is osteochondrosis of the spine. This disease leads to the fact that the intervertebral disc gradually loses water, becomes less elastic, and its height decreases. As a result, the disc loses its ability to absorb loads, which increases the risk of injury during physical exertion. Over time, this can lead to the displacement of part of the disc beyond its anatomical space, which causes the formation of a hernia in the back.
Risk factors for the development of a spinal hernia:
- lifting heavy objects without proper technique;
- spinal injuries, including blows;
- constant exposure to vibration (for example, in drivers);
- sudden and uncoordinated movements;
- prolonged sitting, especially in an incorrect posture (often found in drivers and people who work at a computer);
- obesity, which creates additional stress on the spine;
- incorrect load on the spine due to its curvature (kyphosis, lordosis);
- Posture disorders and working in an uncomfortable position, which leads to chronic overstrain of the back muscles.
Intervertebral hernia during pregnancy
Intervertebral hernia in pregnant women can complicate the process of carrying a child. With an increase in the load on the back and changes in the body, the pain may increase. In particular, hormonal changes contribute to the formation of muscle blocks and increase the load on the intervertebral discs.
During pregnancy, to reduce the risk of exacerbation of the hernia, it is useful to engage in moderate physical activity, which includes:
- regular gymnastic exercises that strengthen the muscles of the back and abdomen;
- following a healthy diet rich in vitamins and minerals that support the health of the spine;
- avoiding prolonged stay in one position, which helps reduce tension in the back;
- wearing a bandage to support the abdomen and reduce the load on the spine;
- using an orthopedic mattress and shoes that provide proper foot support.
Pregnancy can not only worsen the condition of an existing hernia, but also contribute to its development. Chronic pain can reduce a woman’s physical activity, cause nervous tension and stress, which will negatively affect the unborn child.
If signs of a hernia of the spine appear, a pregnant woman should undergo treatment that will be adapted taking into account the gestational age. The doctor will determine the safest approach to childbirth, taking into account all the features of the clinical case, and will offer pain management methods that do not harm the health of the mother and child. It is also important to choose physiotherapy methods that can be safe during pregnancy, such as light massages, water procedures and yoga for pregnant women.
Diagnosis of intervertebral hernia
Diagnosis of intervertebral hernia begins with a history and assessment of symptoms. The doctor may suspect the presence of a hernia based on the patient's complaints, medical history, and physical examination results. The primary symptoms of a spinal hernia may be back pain, numbness, weakness in the limbs, or impaired sensitivity.
The main method for diagnosing intervertebral hernias is magnetic resonance imaging (MRI). This method allows you to display in detail the structure of the spine, its dimensions, the condition of the intervertebral discs, as well as detect degenerative changes and other pathologies. MRI is the most informative method for assessing the condition of the nerve roots and spinal cord, since it does not use ionizing radiation.
An alternative to MRI is multispiral computed tomography (MSCT), which also provides a clear image of the spine and can be used if MRI is impossible due to the presence of metal implants or other contraindications.
If the doctor suspects the presence of a protrusion in the spinal canal, an X-ray contrast study - myelography - may be prescribed. This method involves the introduction of a contrast agent into the cerebrospinal fluid, which allows you to assess the condition of the spinal cord and nerve roots.
No less important are laboratory blood tests that help detect systemic inflammatory processes, autoimmune diseases, infections or diabetes. General and biochemical blood tests can reveal signs of inflammation or metabolic disorders that can affect the development of a hernia.
The listed diagnostic methods provide comprehensive information about the disease, which allows you to establish a correct diagnosis and develop effective treatment tactics.
