Does the external remote controller ’s reading correspond to the actual lengthening in magnetic-controlled growing rods?

ConclusionThe reading on the ERC does not equate to the actual rod lengthening. The authors would recommend that clinicians using the MCGR for the treatment of early-onset scoliosis include pre- and post-extension imaging (radiographs or ultrasound) to confirm extension lengths at each outpatient extension. In centres with ultrasound facilities, we would suggest that patients should have ultrasound to monitor each lengthening after distraction but also 6-month radiographs.Graphic abstractThese slides can be retrieved under Electronic Supplementary Material.
