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

Conditions

  • Limb Length Discrepancy

Interventions

DEVICE

ultrasound measurement

Three different measurements will be obtained using an ultrasound to determine the length gained from lengthening the tibia and/or femur with an internal lengthening rod. Please see the protocol on the locations that will me measured.

DIAGNOSTIC_TEST

X-ray imaging of tibia and/or femur

All patients will have an x-ray with two views anterior-posterior and lateral to measuring the lengthening of the internal rod. Please see the protocol for locations of the measurements being obtained.
