The wedge shape of the 12 thoracic vertebrae is related to congenital development and trauma, and the consequences of this condition include spinal lordosis, thoracic back pain, and neurological abnormalities. 1. Spinal lordosis: Prolonged wedge-shaped changes of the 12 thoracic vertebrae will lead to abnormal spinal curvature, which will further lead to localized lordosis of the thoracolumbar region, resulting in abnormal body shape. 2. Thoracic back pain: abnormal spinal structure will easily cause swelling of the surrounding soft tissues and fasciitis, which will further lead to thoracic back pain and discomfort. 3. Abnormal neurological function: wedge-shaped changes caused by some fractures will cause narrowing of the spinal canal and nerve root compression, which will further lead to abnormal neurological function, causing numbness and weakness of the lower limbs and limitation of activities. Thoracic 12 vertebral wedge-shaped change is caused by trauma, accompanied by the posterior edge of the vertebral body bone discontinuity, you need to consult a doctor in a timely manner for examination and diagnosis of the condition, and then standardized treatment under the guidance of the clinician, so as to avoid causing delays in the condition.
