Your doctor may recommend that you intersperse rest with periods of standing or walking throughout the day. You can start with even a few minutes of standing or walking at a time, performed multiple times a day. You can then gradually increase the time you spend walking. Try to avoid sitting for long periods of time, as sitting can place greater loads on your spine than standing does. When you are sitting, try to sit upright rather than slouched, with proper support for your back.
Lie flat on your back using a small pillow or folded towel if necessary to support head so long as chin is not tucked into chest; bend both legs to about 90 degrees, feet flat; bring arms out from the body slightly, palms up. Using this position daily can help align the spine in a gentle manner and help stretch out tight muscles.
Once you get clearance from your doctor that the fracture site has healed, exercises can be started under the supervision of a physical therapist, ideally one who has undergone Bone Fit™ training.
