The recovery time after a lumbar spine fusion can range anywhere from a month to six months, according to MedlinePlus. Recovery time will vary among individuals and depend on factors such as presurgical condition and age.
To minimize recovery time, carefully comply with all postsurgical instructions, such as limiting physical activity and wearing a brace for support, as recommended by MedlinePlus. Physical therapy is sometimes prescribed to promote proper recovery after surgery. In some cases, pain medicine is recommended prior to resuming normal activity during the early stages of recovery. Seek medical attention in the event of excessive pain or pain that does not respond to medication.
