Recovery from lumbar fusion surgery usually takes about six months. Lumbar fusion surgery first ensures complete fusion of the bones, which can typically take up to about three months. After complete fusion, patients also need to adhere to the strength training of the lumbar back muscles in order to make the atrophied lumbar muscles gradually recover and be able to provide sufficient protection for the lumbar vertebrae, and it takes three to six months of exercise to see obvious therapeutic effects. In addition, nutrition should be strengthened to ensure that the rehabilitation effect can be implemented. After about half a year, lumbar spine fusion patients can be completely recovered, at this time the patient can walk with normal weight bearing, and be able to insist on work and moderate exercise.
