Ultrasound Use to Measure Magnetically Controlled Growing Rods

United States10 participantsStarted 2025-09-05

Plain-language summary

The goal of this clinical trial is to learn if an ultrasound can measure the length of an internal tibia and femur lengthening rod. The main questions it aims to answer are: Can an ultrasound be used to measure the length of an internal magnetic lengthening nail in a tibia or femur? Can an ultrasound measure the rod lengthening as well as an ultrasound? Researchers will compare the length of an internal magnetic lengthening rod with both x-rays and ultrasound Participants will: Have standard x-rays every week They will also have an ultrasound of the femur or tibia
