Question
QUESTION: I have a Harrington rod, attached to my back in 1982.  I have been told I need a MRI or CT scan on my head, after a one off black out/faint/fit?
Were the Harrington rod only ever made from stainless steel, and how will this react to, and affect the readings, of the MRI and or CAT scan?  If the MRI is giant magnetics, will this rip the rod away from the spine?
Thanks in advance,

ANSWER: Richard,

Although I am not a physician or surgeon, I can tell you what my research showed.  The CT scan is not magnetic and will probably be the test that your physician recommends. To the best of my knowledge, the rods will not be a concern for the CT scan.  I have metal in my body and have had multiple CT scans without any problems physically or in the CT readings. Other Harrington rod patients have had MRIs done and some have reported heat or other pain both during the MRI and afterward.

Harrington rods are made of stainless steel or titanium, depending on the date of surgery.  The date of your surgery would indicate stainless steel but your medical records will show for certain what type of rod was placed.

As always, your physician has the most knowledge about your personal case and he/she is in the best position to talk with you on the proper test, its risks, its benefits, and other helpful information.

Thank you for your question.  I hope this answer was useful for you.

QUESTION: Thank you for your quick reply.  I have a followup question for you.
Did the Harrington rod patients, that reported heat or other pain during and after their MRI scan, have stainless steel or titanium rods, and how much heat or pain?

Answer
Richard,

In reviewing my research notes on your question, I was unable to determine whether the rods were titanium or stainless steel but I would assume from the ages of the patients and their surgery dates that the rods were stainless steel.  The reports of heat and pain ranged from heat and discomfort during the MRI where the patient signaled the technician and stopped the MRI to a patient that reported pain up to three days following the MRI.

Again, I advise checking with your physician to get the most detailed information as it relates to your specific case and your type of rods.

Thank you for your question, Richard.
