Question: I know someone who had spinal fusion and rods placed in her back. She was told to have X-rays every six months because if screws broke, she could be paralyzed. Is this possible?
Dr. Hibberd’s answer:
Spinal Fusion with rods is major surgery. It is highly unusual to be advised to have X-rays every six months to check for broken hardware. The hardware used for spinal surgery will not bend, break, or migrate without excessive direct trauma. Even in the case of auto accidents, it would be an unusual and uncommon event.
Screws do not break easily, and we do not recommend routine scans to look for breakage unless we suspect incorrect hardware alignment or a patient suffers back pain from significant trauma such as in a fall from a height or a serious auto accident. Any breakage or hardware migration almost always will produce symptoms.
The hardware is more resilient than bone itself. Routine back X-rays for spinal surgery patients who are not having symptoms is bad medicine and ill advised. You will need a single X-ray to assess the hardware after surgery, and a followup in six months to one year. But that’s all that is usually needed to assure stability of the bone structure.
There is an exception to this — when rods and wires are placed for scoliosis correction, and periodic adjustments need to be made to hardware. But the fear that a screw could break, causing paralysis, sounds to me very suspect, and I would seek a second opinion.
