Mild compression fracture of the 12th thoracic vertebra is less severe and is usually treated conservatively, requiring the patient to be absolutely bedridden to avoid secondary injury. For younger patients with no underlying disease, simple vertebral compression fracture without spinal nerve injury, severe displacement of the vertebral body, or spinal stenosis, the time required is shorter, and the patient can be discharged from the bed after 3 months of fracture healing, and can gradually return to mobility under the protection of a brace. For older patients with serious underlying diseases such as chronic renal failure, severe osteoporosis, or vertebral compression fracture combined with spinal cord nerve injury, severe displacement of the vertebral body, or spinal stenosis, the time required is longer, usually about 3 months for the fracture to heal, and it will take about 1 year for full recovery.
