Degeneration of the lumbar spine

Introduction The lumbar vertebrae are composed of five vertebral bodies. The nerve holes located at the posterior side of the vertebral body extend out five pairs of lumbar sacral nerves. These phrenic nerves, together with the nerves of the lower sacral vertebrae, constitute the largest peripheral nerve of the human body. - sciatic nerve. When the spurs proliferate with age, they are pressed into the nerve holes, causing annoying symptoms such as back pain and sciatica. The main cause of low back pain is degeneration of the lumbar disc. The degeneration of the lumbar disc does not only occur in the elderly. 40% of young people aged 20 to 30 also have lumbar disc herniation, which is the main reason.

The cause of lumbar degeneration:

The main cause of low back pain is degeneration of the lumbar disc. The degeneration of the lumbar disc does not only occur in the elderly. 40% of young people aged 20 to 30 also have lumbar disc herniation, which is the main reason.

Diagnosis of lumbar degeneration:

The patient often feels lower back pain after sitting for a long time, standing for a long time, or lying for a long time, and often passes to the buttocks or lower limbs on both sides; if accompanied by nerve compression, there will be lower extremity numbness, weakness, or reduced reflex performance.

Differential diagnosis

Differential diagnosis of symptoms of lumbar degeneration and confusion:

1, degeneration of the intervertebral disc: intervertebral disc degeneration and death are inevitable, and occur in varying degrees to everyone. But not everyone who has a degenerative lumbar vertebra will feel pain. Many people who seem to have normal waist have disc herniation? Degenerative changes and MRI findings of spinal stenosis. It is important to recognize that the condition of each patient is different and that not every person with degenerative disc changes has symptoms. Degenerative discs can lead to several different symptoms, including lumbar pain, leg pain, and weakness caused by nerve root compression. The cause of these symptoms is intervertebral disc wear, because the disc loses its original function and causes pain once it is worn, and if the disc shrinks, the space for the nerve root becomes smaller. Intervertebral disc wear between adjacent vertebral bodies reduces the flexibility of the entire lumbar spine. The result is the appearance of pain and stiffness in the lower back, especially at the end of a hard day's work.

2, lumbar bulging: lumbar disc herniation, also known as lumbar disc herniation or nucleus pulposus, when the labor or sports activities suffered from twisting and impacting at the waist, lifting heavy objects with excessive force, overwork and other injuries Causes the rupture of the intervertebral disc fibers, and the nucleus pulposus tissue escapes from the rupture port, stimulating or compressing the spinal nerve roots and causing pain in the lower back and leg.

3, lumbar vertebrae: lumbar vertebrae: refers to the fifth lumbar vertebrae all or part of the transformation into the shape of the atlas, making it part of the humeral block clinically with the fifth lumbar vertebrae on one side or both sides of the transverse process hypertrophy into a wing and tibia One piece is more common, and more with the humerus to form a pseudo joint; and a few of the fifth lumbar vertebral body (together with the transverse process) and the humerus healed together such a deformity is more common. It is one of the classifications of the transitional spine.

The patient often feels lower back pain after sitting for a long time, standing for a long time, or lying for a long time, and often passes to the buttocks or lower limbs on both sides; if accompanied by nerve compression, there will be lower extremity numbness, weakness, or reduced reflex performance.
