Loss of vertebral body height due to premature postoperative activity. Depending on the degree of vertebral body compression and encroachment of the spinal canal as well as the accompanying symptoms, the decision was made to treat conservatively or surgically. 1. If the vertebral body is compressed due to activity after surgery, if the compression is less than 50%, the encroachment of the spinal canal is less than 30%, and there is no symptom of nerve compression, it is recommended to continue external fixation with a brace (total of 10~12 postoperative days). It is recommended to continue external fixation with a brace (for a total of 10 to 12 weeks after surgery) and bed rest. Oral pain medication (celecoxib capsules) and anti-swelling medication (dexamethasone tablets) can be taken, and the vertebral body X-ray should be reviewed regularly until the vertebral fracture is completely healed. 2. If the vertebral body is lost more than 50% after surgery, or the vertebral canal encroachment is more than 30%, and there are symptoms of nerve compression such as throbbing pain in the lower limbs, it is recommended to have bed rest and observation first, with external fixation of the brace, oral pain relieving drugs, anti-swelling drugs, and nutritive drugs (methylcobalamin tablets), and then review the X-ray after 2 weeks, and if there is no improvement of the imaging results and symptoms, it is recommended to reopen the surgery after 3 months. Postoperative activities too early led to loss of vertebral height recommended active consultation, physician-guided treatment.
