The pain in the back of the foot more than 50 days after the lumbar compression fracture surgery may be due to the nerve damage has not yet recovered, the soft tissue adhesion caused by prolonged braking and the rehabilitation training. 1. Nerve damage: compression fracture may cause nerve damage, the purpose of surgery is to restore the height and stability of the vertebral body, and it takes time for the damaged nerve tissues to recover, so it is normal for pain to occur during the recovery process. In addition, if you choose open surgery, the surgery may cause adhesion of nerve tissue, which may also lead to postoperative pain. 2. Soft tissue adhesion, rehabilitation: Before or after surgery, if the patient has a long time braking, it may cause adhesion, atrophy or contracture of the soft tissue of the foot. During postoperative rehabilitation, the soft tissues are re-stimulated by pulling and restoring local microcirculation, which may also lead to pain in the back of the foot. In addition, conditions such as intense and prolonged rehabilitation and incorrect posture may also lead to the occurrence of the above symptoms. If the pain symptoms are severe, or if the symptoms persist without improvement, you should go to the hospital to clarify the cause and then target treatment.
