The purpose of rehabilitation treatment is to prevent trunk muscle atrophy, promote fracture healing, restore spinal stability and flexibility, prevent lower back pain and eliminate the adverse effects of long-term bed rest on the organism. Stable fractures are divided into stable fractures and unstable fractures. A simple wedge-shaped compression of the vertebral body not exceeding 1/3 of the original height of the anterior edge of the vertebral body is called a stable fracture; a vertebral body fracture combined with accessory fracture, dislocation, interspinous ligament rupture, spinal cord injury and severe vertebral body comminution fracture is called an unstable fracture. 1.Stable fracture When the healing period is rehabilitated without repositioning and fixation, bed rest for about a week and start the lumbar back muscle training. The training intensity and time should be gradually increased and avoid obvious local pain. After 4-5 weeks, if there is no pain when doing the prone exercise, you can get up and stand and walk, and the time will be gradually extended. The prone position should be used to get out of bed. When rising from the prone position, first lie prone on the edge of the bed, with one leg on the ground first, then support the upper body, and then put down the other leg into the standing position, without passing through the sitting position in the middle to avoid lumbar flexion, and in the opposite order when lying down from the standing position. The fracture is basically healed before the sitting position, but should avoid sitting with the waist flexed. The lumbar brace can be worn in the standing and sitting positions. In case of cast fixation, isometric contraction training of the recumbent back muscles can be started after the cast dries, and after 1-2 weeks, moderate abdominal exercises can be added. When there is no local pain, you can get up to stand and walk, and do upper and lower limb activities. The recovery period is about 3 months after the injury, when the fracture is healed and the cast is removed for further lumbar back muscle and abdominal muscle training and lumbar spine flexibility exercises. 2.Unstable fracture mostly requires surgery, about 1 month of postoperative bed rest, followed by plaster undershirt fixation for 3-4 months. Rehabilitation training should be delayed appropriately. Light back training should be started 2-3 weeks after surgery, and isometric contraction training of back muscles and light abdominal muscle training should be done after the cast dries.
