Ultrasound may spare kids from unnecessary x-rays during limb lengthening
NCT ID NCT07212049
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether ultrasound can accurately measure the length of internal magnetic rods used to lengthen leg bones in children and young adults. Ten participants will get both weekly X-rays and ultrasound measurements to compare. If ultrasound works just as well, it could reduce radiation exposure from repeated X-rays.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- ultrasound measurement
- What this could lead to
- If successful, this could reduce the need for frequent X-rays in children undergoing limb lengthening, lowering radiation exposure.
- What could go wrong
- This is a very small early study with only 10 participants, so results may not apply to all patients. Ultrasound may not be as accurate as X-rays for this purpose.
