Question
My 1.5-year-old child has unequal legs, with a difference of about 1.2 cm. Although an X-ray showed no issues, the child walks unsteadily! How often can X-rays be done with radiation within a year? The last detailed X-ray was on September 30th. The child has just started walking and is not steady. It’s now December 2nd, and although the child’s walking has improved, there is still a feeling of unease. Can I bring the child for another detailed X-ray examination?
Answer
In this case, if a 1.5-year-old child has unequal legs, they can be examined by an orthopedist to check for congenital patellar disk injury. If congenital patellar disk injury has been ruled out and the last X-ray was conducted on September 30th, there is no need to have frequent examinations at this time, as it is not meaningful.
