Recovery from spinal fusion surgery takes longer than with other types of spinal surgery. Patients often have a 3- or 4-day hospital stay, with a possible stay on a rehabilitation unit. Patients typically wear a brace immediately after surgery. Rehabilitation is often necessary to rebuild strength and functioning. Activity level is gradually increased. Depending on the patient's age and health status, getting back to normal functioning can happen within 2 months, or up to 6 months later.
