How long it takes to sit up after a compression fracture in the thoracic spine must be determined by the specific treatment. If the fracture is surgically repositioned by incision and fixed using the pedicle nail, you must wait 1-2 weeks after surgery for the wound to be completely stable before you can sit up. If vertebroplasty is done after compression fracture in middle-aged and elderly people, the fracture end is more stable after surgery, and they can sit up and even go down to do functional exercises for walking on the 2nd day after surgery. If conservative treatment of bed rest is performed after thoracic compression fracture, one must be bedridden for about 6-8 weeks and wait for the fracture to be completely stabilized before reviewing the photos and seeing significant bone scab growth before sitting up.
