A lumbar herniated disc fusion can usually be out of bed in about a month. Lumbar disc herniation fusion is mainly used for the treatment of severe lumbar disc herniation. The procedure is more complicated, which requires removing the vertebral plate for decompression, retracting the spinal cord to both sides, exposing the herniated lumbar disc, and removing it completely. After the surgery, the stability of the lumbar spine will be affected, and it is necessary to rest in bed for about a month before getting out of bed, walking appropriately, and the amount of activity should not be too large. Generally, you can walk normally about three months after lumbar disc herniation fusion surgery, but you must wear lumbar support, pay attention to rest, no strenuous exercise, no bending over to bear weight or do heavy physical work, and avoid prolonged sitting and squatting. During the recovery period, it is recommended to go to the hospital regularly for rechecking, pay attention to the recovery of lumbar spine, and go to the hospital in time if you find any abnormality.
