Compensatory lumbar lordosis

Introduction The clinical manifestations of osteoarthritis are mainly hip pain. When the condition develops severely, the hip joint is flexed and adducted, compensatory lumbar lordosis, lower back pain, and even unable to walk. It is related to age, obesity, inflammation, trauma and genetic factors. Its pathological features are degeneration of articular cartilage, subchondral bone sclerosis or cystic changes, joint bone hyperplasia, synovial hyperplasia, joint capsule contracture, ligament relaxation or contracture, muscle atrophy and so on.

Cause

A variety of factors cause joint disease caused by fibroplasia, cleft palate, ulceration, and loss of articular cartilage. The cause is not clear, and its occurrence is related to age, obesity, inflammation, trauma and genetic factors. Its pathological features are degeneration of articular cartilage, subchondral bone sclerosis or cystic changes, joint bone hyperplasia, synovial hyperplasia, joint capsule contracture, ligament relaxation or contracture, muscle atrophy and so on.

X-ray examination of spine MRI

The synovial fluid was tested for color, transparency and mucin clot test. The white blood cell count was between 200 and 2000/mm3. There was no bacteria or crystallography on the microscopic examination, but cartilage fragments and fibers were visible. The number of fragments could be used to roughly estimate cartilage degradation. degree.

X-ray plain films generally have typical manifestations, mainly narrow joint space, subchondral bone sclerosis, marginal lip-like changes and osteophyte formation, and intracapsular cystic changes around the joint. In addition to the above changes in the spine, such as the nucleus pulposus protruding into the upper and lower vertebral bodies to form subchondral nodules, the so-called Schmorl's nodes, sometimes associated with spinal space-occupying lesions. CT and MRI examination Can clearly show joint lesions, disc herniation, thickening of the posterior longitudinal ligament, etc., has a diagnostic value for osteoarthritis.

Differential diagnosis

Differential diagnosis of compensatory lumbar lordosis:

1, lumbar hypertrophy: lumbar hypertrophy, also known as hypertrophic spondylitis or degenerative spondylitis, is a common cause of low back pain in the elderly. When people reach middle age, the lumbar vertebrae begin to proliferate, hypertrophy, and long bone spurs. Almost all the elderly have lumbar hypertrophy. On the X-slice, the sides of the spine are sharply pointed, like the raised lips, so some X-rays are reported as "lip-like hyperplasia."

2, lumbar disc herniation: lumbar disc herniation, the full name of the medical should be "lumbar disc herniation", the English name has the following kinds: lumbar disc heriation rupture of the lumbarintervertebral disk; slipped lumbar intervertebarl disc; herniated lumbar disc and so on. Because of the different names, the American Academy of Orthopaedic Surgeons defined the nomenclature of lumbar disc disease as follows:

First, the intervertebral disc is normal: the intervertebral disc has no degeneration, and all intervertebral disc tissue is in the intervertebral disc.

Second, intervertebral disc bulging: intervertebral disc annulus uniformity beyond the intervertebral space range, intervertebral disc tissue is not limited.

Third, the disc herniation (protruded): the disc tissue localized displacement beyond the intervertebral space. The displaced intervertebral disc tissue is still connected to the original intervertebral disc tissue, and the diameter of the basal continuum is larger than the displaced intervertebral disc portion beyond the intervertebral space.

Fourth, the intervertebral disc is extruded: the diameter of the displaced intervertebral disc tissue is larger than the continuous part of the base and moves to the outside of the intervertebral space. The intervertebral disc tissue block is larger than the ruptured intervertebral disc space and is located in the spinal canal through the fissure.

Domestic lumbar disc herniation also includes lumbar disc annulus rupture, lumbar disc herniation, lumbar intervertebral disc herniation, lumbar cartilage rupture and other titles. Although the names and meanings of the above diseases are different, the current more uniform title is: lumbar disc herniation.

In the name of the Chinese medicine, there is no name for lumbar disc herniation. According to the clinical manifestations of the disease, it can be attributed to low back pain, low back pain and sickness. Instead, the disease is attributed to the category of low back pain and low back pain.

3, 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.
