Why does lumbar spinal nerve compression occur?

People's current lifestyle has great disadvantages for their physical health. For example, habits such as playing computer or mobile phone for a long time may lead to cervical spondylosis and even compression of the lumbar spinal nerves. However, everyone knows about cervical spondylosis, but when it comes to compression of the lumbar spinal nerves, few friends clearly understand why this condition occurs.

Compression of the lumbar sacral nerves will inevitably lead to incomplete paraplegia. Since the condition is unknown, if you consult, please provide a detailed description of the cause of the disease, age of onset, time of onset, exact location of onset, examination results, current symptoms, and previous treatments. The more detailed the better. Only through analysis and evaluation of the condition can we agree on treatment and treatment measures or plans to see if we can help you.

When muscles are overloaded and maintain a state of strong contraction for a long time, the pressure within the muscles increases, blood supply is insufficient, ischemia and hypoxia occur, energy is not fully replenished, muscle glycogen metabolism is incomplete, and the large amount of lactic acid and other metabolic products produced cannot be cleared in time, leading to muscle atrophy, edema and adhesion, and muscle strain. After muscle strain, muscle strength weakens, and the stress of maintaining posture is concentrated on the ligaments and joint capsules. The ligaments and joint capsules are subjected to excessive traction, their elasticity weakens, and edema occurs, resulting in a series of changes such as adhesion, fibrosis, and hypertrophy, and finally ligament and joint strain occurs.

Strain of the lumbar sacral region is related to local anatomical characteristics. The lumbar vertebrae form an angle of about 120 degrees between the 5th lumbar vertebra and the 1st sacral vertebra, with the more mobile lumbar vertebrae above and the fixed sacral vertebrae below. This structure requires the lumbar vertebrae to withstand greater extension, flexion, rotation and shear stresses. Frequent, repeated, and continuous mechanical stress on the soft tissues and bone joints of the lumbar region will cause subtle changes in the local tissue structure, physical and chemical properties, and movement patterns. When long-term, small amounts of subtle changes accumulate to a level that exceeds the compensatory capacity of the soft and hard tissues of the lumbar region, lumbar strain will occur.

Some people believe that excessive lumbar lordosis will cause the lumbar-sacral angle to decrease, which will increase the shear stress in the lumbar-sacral region. If the vertical line of the center of the third lumbar vertebra falls in front of the sacral surface, the lumbosacral articular process and anterior ligament will be subjected to greater stress. The angle formed by the vertical line passing through the lumbosacral joint surface and the ground is greater than 30. The lumbar sacral region is vulnerable to damage. Poor muscle development, increased lumbar lordosis, obesity, weight gain, and abdominal bulging will all increase the shear stress in the lumbar sacral region and easily cause strain.

Now that you know why lumbar spinal nerve compression occurs, it is recommended that you pay attention to it in daily life and avoid factors that cause lumbar spinal nerve compression. If you feel any discomfort in your body, such as frequent lumbar pain, you must pay attention to seek medical treatment in time. Only in this way can you avoid the disease from getting worse.
