The recovery period for open lumbar spine surgery is generally 1 to 3 months, and the postoperative recovery period for patients with combined nerve injury ranges from half a year to two years. In open lumbar spine surgery, if it is simply a lumbar vertebra segment, no complications occur after surgery, generally 1 to 1.5 months basically can recover and can carry on simple life and activities; if more segments are involved, the surgical trauma is relatively increased, the recovery will be slower, and it generally takes about three months to make the intervertebral body reach a state of complete fusion, so that it can carry on a normal work and life. If the lumbar spine injury is more serious or combined with nerve injury, the postoperative recovery period is generally calculated on a six-month cycle, with the fastest functional recovery within six months, and then the functional recovery gradually slows down until it basically stops in about two years. Because it is currently believed that the nerve tissue can not be regenerated, and can only rely on the axon growth of the uninjured nerve to replace the function of the injured nerve, and the axon growth rate is about 1mm per day. Patients after open lumbar spine surgery should seize the golden period of recovery and actively follow the doctor’s instructions for rehabilitation training.
