After minimally invasive foramenoscopy for lumbar spine, purely removing the nucleus pulposus, generally about 1 month to recover, implantation of pedicle screws and so on during the operation, about three months to recover, the nerves have irreversible damage, it is generally difficult to recover. 1. Simple removal of the nucleus pulposus: Minimally invasive foramenoscopic surgery is performed on the lumbar spine. If the nucleus pulposus is simply removed and no other operations are performed, recovery can be achieved in about one week after the surgery, but the healing period of the soft tissues is about one month. 2. Implantation of pedicle screws: If other operations are performed during the surgery, such as the implantation of pedicle screws or interbody fusion devices, the postoperative recovery time, which will be relatively longer, is about 3 months. 3. Irreversible nerve damage: Minimally invasive foramenoscopic surgery on the lumbar spine only removes the protruding discs so that the nerves are not compressed. If the course of the disease is longer and the protrusion is more serious, resulting in irreversible damage to the nerves, even if the discs are removed for the corresponding decompression, the residual symptoms of numbness of the legs and feet as well as the residual symptoms of sensory abnormalities of the nerves will be left behind, which is generally very difficult to recover from. Consultation with a specialist is recommended for specific recovery time.
