According to MedlinePlus, the average recovery time for back surgery ranges from a few weeks to six months depending on what type of back surgery is performed. The severity of a patient's injury or condition before surgery also affects recovery time.
MedlinePlus notes that recovery from a microdiskectomy surgery is the quickest. Recovery time for a diskectomy or foraminotomy procedure is a few weeks in duration. Typical recovery time for a laminectomy or spinal fusion is a minimum of three to four months. MedlinePlus mentions that older adults usually require a longer recovery period of up to six months after spinal fusion.
