Spinal curvature is divided into congenital spinal curvature, acquired spinal curvature and idiopathic spinal curvature according to its nature. Congenital spinal curvature refers to abnormalities in the spinal structure, that is, triangular hemivertebral bodies, butterfly-shaped vertebrae, fused vertebrae, and abnormal rib development after birth, causing the spine to tilt, leading to scoliosis or kyphosis. It is rare clinically and often requires surgical correction. So, what is the cause of acquired spinal curvature? With these questions, we visited some experts from orthopedic hospitals. Causes of acquired spinal curvature: 1. Osteoporotic spinal curvature: Osteoporotic vertebrae are deformed, resulting in unequal width of the vertebrae gaps, which will cause spinal curvature. 2. Maltrophic spinal curvature: Children with rickets due to vitamin D deficiency may also develop spinal curvature. 3. Postural and functional spinal curvature: often caused by some incorrect posture, often found in school-age children. This type of spinal curvature deformity is not serious and can occur when the patient is lying on his back or hanging from a horizontal bar with both hands. The deformity can disappear automatically. 4. Neuropathic spinal curvature: caused by imbalance of muscle tension due to poliomyelitis, neurofibroma, syringomyelia, cerebral palsy, etc. The younger the patient is at onset, the more severe the curvature deformity will be. 5. Pathological spinal curvature of the chest: Suffering from suppurative or tuberculous pleurisy in childhood, the costal pleura is excessively thickened and contracts; or thoracoplasty in childhood disrupts the balance of the spine during development. Both can cause spinal curvature. The above content is an introduction to how to correct spinal curvature. I hope it will be helpful to you.
