Lumbar spur

Introduction Lumbar spur is the bone hyperplasia of the lumbar spine. The simple long spur is only a protective physiological response of the human body, that is, the normal function of self-defense, compensation, regeneration, repair and reconstruction, and usually does not belong to the category of disease. Only when there is bone hyperplasia, and there are corresponding clinical symptoms or signs, such as pain associated with the waist, activity disorders, etc., can be called bone hyperplasia or osteoarthropathy

Cause

The cause of lumbar spurs:

The bone hyperplasia of the lumbar vertebrae is because after middle age, with the increase of age, the physiological functions of the cells in the body tissues gradually decline and aging, the degenerated intervertebral disc gradually loses water, the intervertebral space narrows, and the fiber ring relaxes to the periphery. Out, the vertebral body is unstable, and the annulus tears outside the edge of the vertebral body, leading to the protrusion of the nucleus pulposus. The periosteum of the posterior longitudinal ligament is lifted up, and new bone is formed underneath to form bone spur or bone hyperplasia. Some people think that after the disc degeneration and atrophy, the vertebral body is tilted forward, the front edge of the vertebral body is blocked by the anterior longitudinal ligament in the midline, the periosteum on both sides is picked up, and new bone is formed under the periosteum. In addition, the local compression factor is also the main cause of bone hyperplasia, the lumbar vertebral body edge compression is heavier, so the occurrence of bone hyperplasia is also more common here.

Examination and diagnosis of lumbar spurs:

(1) The patients with this disease are mostly middle-aged and elderly people over 40 years old, accompanied by lumbar stiffness pain or numbness of lower extremities. Some patients may have abnormal lumbar vertebral curvature; some muscles on both sides of the lumbar spine have tenderness.

(2) changes in lumbar X-ray films (positive position, lateral position, left and right oblique position), such as patients with lumbar curvature abnormalities, lumbar scoliosis, lumbar vertebral body space narrowing, lumbar vertebral body and facet joint hyperplasia, Lumbar spondylolisthesis, intervertebral foramen stenosis and other changes.

Differential diagnosis

Symptoms of wavy long bone spurs:

The ankle can have a skin sputum, forming a tail: the abnormal skin of the lumbosacral region is a clinical manifestation of the tethered cord syndrome, and the individual sputum can have a skin sac and form a tail. Tethered cord syndrome (TCS) is a syndrome in which a spinal cord or a cone is pulled due to various congenital and acquired causes, resulting in a series of neurological dysfunctions and malformations. Because the spinal cord is pulled more often in the lumbosacral medulla, causing the cone to be abnormally low, it is also called the lower spinal cord.

Lumbar disc herniation: The full name of the medicine should be "lumbar disc herniation", and its 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 have defined the nomenclature of lumbar disc disease as follows: 1. The normal intervertebral disc of the intervertebral disc has no degeneration, and all intervertebral disc tissue is in the intervertebral disc. Second, the bulging of the intervertebral disc annulus fibrosis annular uniformity beyond the intervertebral space range, the intervertebral disc tissue is not limited. Third, the disc herniation (protruded) 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. IV. Intervertebral disc extruding The diameter of the displaced intervertebral disc tissue is larger than the continuum of the basal ganglia and moves beyond 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.

Compensatory lumbar lordosis: The clinical manifestations of osteoarthritis are mainly hip pain. When the condition develops seriously, hip flexion adduction, compensatory lumbar lordosis, lower back pain, and even walking.
