Thoracic lumbar

Introduction Thoracic lumbar metaplasia: refers to the 12th thoracic vertebrae that loses the ribs and forms a lumbar vertebrae. If the 5th lumbar vertebrae are not accompanied by delirium, the lumbar spine is still present and has lumbar function.

Cause

Induced cause of thoracic lumbar

The normal spine consists of 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae 5 sacral vertebrae, and 4 vertebral vertebrae. At 4th to 7th week, the vertebrae begin to differentiate, and the vertebral body is at the center of the bilateral vertebral arch. And the additional osteogenesis centers of the lateral sides began to appear at the 20th week and the 30th week of the 10th week of the embryo. Complete vertebral vertebral arch and lateral healing after birth ~ 8 years old. The vertebral arches healed at the age of 15 to 15 years old at the age of 15 years. A tarsal plate appears on the upper and lower sides of each vertebral body and is placed on the ear surface or An additional osteogenesis center appears below the tarsal plate and the vertebral body begins to fuse to the age of 30 when the sacral vertebral body merges into a tibia.

During this process, certain factors affecting development can cause alienation and cause migration of the vertebral body.

Differential diagnosis

Symptoms of thoracic lumbar edema:

Thoracic vertebrae pain: It is the main clinical manifestation of the symptoms of thoracic spondylosis, including thoracic vertebrae hyperplasia, spinal stenosis; thoracic compression fracture, dislocation, scoliosis, fascia incarceration; and thoracic disc herniation. Lateral thoracic vertebral slices showed lip-like hyperplasia of the anterior border of the vertebral body. Most of them show a widening of the thoracic intervertebral space narrowing, cartilage plate sclerosis, anterior or lateral margin of the vertebral body. In some cases, the shadows of the Smolen nodules, the curvature of the thoracic spine, and the deepening of the physiological curvature were observed.

Thoracic scoliosis: refers to a spinal deformity in which one or more vertebral segments of the spine are curved laterally with vertebral body rotation. Thoracic scoliosis has a high incidence in the modern population, affecting a wide population, a large number, and gradually becoming younger. It is closely related to the professional characteristics of the modern population and work and living habits. It affects a wide range of human bodies, affects many tissues and organs, and the symptoms are complicated, including not only skeletal muscles. Neurovascular, visceral digestive system, cardiovascular circulatory system, etc. The harm caused to people is serious.

Thoracic deformity: The thoracic spine is kyphosis during the embryonic period and gradually becomes lordosis after the child is sitting up. This change is called secondary curvature. The formation of secondary curvature is generally due to the thickness of the vertebral body and the anterior and posterior disc. The presence of thoracic physiologic curvature can increase the elasticity of the thoracic spine, reduce and cushion the shock of gravity, and prevent damage to the spinal cord and brain. Due to long-term sitting posture, poor sleeping posture and dehydration and degeneration of the nucleus pulposus of the intervertebral disc, the lordosis of the thoracic vertebra can gradually disappear, and even the straight or reverse bending, that is, the convexity of the back, which causes the thoracic kyphosis.
