Normally lumbar fusion can return to normal 3 to 6 months after surgery. Lumbar fusion is a basic technique for treating lumbar spine disorders, and can be used for lumbar spinal stenosis, lumbar instability, degenerative disc disease, degenerative scoliosis, degenerative vertebral slippage, and pseudoarthrosis. It usually takes 3 to 6 months to return to normal after lumbar fusion surgery, with gradual recovery usually occurring in about 3 months and full recovery in about 6 months. It takes a gradual process to get back to normal after lumbar fusion surgery. Generally speaking, within 3 months, you should wear a lumbar girdle or support, and you can carry out light activities under its protection. At this time, the fusion already has a certain strength, and the bone scabs begin to form, so you can do some functional training. However, at least 6 months the strength of the bony fusion can resume normal life and sports activities. How long does it take for lumbar spine fusion surgery to return to normal is also related to the patient’s physical condition, age and functional exercises, etc. It is recommended to treat and cooperate under the guidance of the doctor.
