Pain associated with vertebral compression fractures isn’t fully understood. It’s likely there is pain coming from the bone and from the nearby nerves. Movement in either direction can compress the bone.
Bending forward puts pressure on front half of the vertebra. Extension compresses the back half of the bone and also narrows the opening where the nerves come through. In addition, when it hurts, the patient stops moving. The natural flow of motion and muscle activity actually helps keep the patient from getting stiff and deconditioned. Without movement the pain and stiffness increases.
As difficult as it may sound, movement and especially straightening up to full height helps with this condition. A physical therapist can help patients with this type of fracture learn the right activities and exercises to do to heal in the best spinal position possible. The therapist can also teach you how to use your breathing to reduce the pain and how to sleep at night for optimal healing.
