How long does it typically take to recover after a lumbar spinal fusion surgery?

Recovery after spinal fusion surgery typically takes four to six months for older patients, but it may take as little as four to six weeks for young patients who are otherwise healthy, according to MedlinePlus. Recovery time is also affected by how bad the condition was before surgery.

Spinal fusion patients may be required to wear a back brace and to receive physical therapy during recovery, as MedlinePlus explains. They should avoid sitting for long periods, bending at the waist, carrying anything heavier than a milk carton and lifting objects over their heads. They should not drive for the first two weeks of their recovery period and should only walk for short distances during that time.
