Lumbar fusion surgery: when joining spine bones is considered, and when it isn't
Fusion joins two or more bones of the lower spine so they heal as one. Dr. Rajesh Pathi will explain when this is considered, what it involves, and why it is not needed for most back pain.
When to seek emergency care. New loss of bladder or bowel control, numbness around the saddle area, or rapidly worsening weakness in the legs need emergency care. Call 108 or go to the nearest emergency department.
Most back pain does not need fusion
Fusion is reserved for specific problems, such as an unstable spine, and only after careful evaluation. Many people with back pain are never advised to have it.
