Stable fractures and unstable fractures are classified as follows: 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. The purpose of rehabilitation treatment is to prevent trunk muscle atrophy, promote fracture healing, restore the stability and flexibility of the spine, prevent lower back pain and eliminate the adverse effects of long-term bed rest on the organism. 1.Stable fracture Rehabilitation during the healing period: When not repositioning and fixing, bed rest for a week or so, start the lumbar back muscle training. The intensity and duration of training should be gradually increased, and avoid obvious local pain, see Figure 29-1. Avoid forward flexion and rotation of the spine during training and turning in bed. 4~5 weeks later, if there is no pain when doing prone exercises, you can get up and stand and walk, and the time is 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 plaster fixation, isometric contraction training of the recumbent back muscles can be started after the plaster 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. Recovery period rehabilitation: about 3 months after the injury, 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 plaster dries.
