Smartphone application technique for localising magnetically controlled growth rod actuators: the Oxford Magnetic Counter App Technique (TOMCAT)

The purpose of this study is to report a novel smartphone app technique to localise a magnetically controlled growing rod (MCGR) actuator, along with determining this novel technique accuracy compared to current tactile localisation techniques through an experimental study. Five spinal surgery fellows recorded attempts localising the MCGR magnetic actuator using a novel smartphone app technique, MAGEC Wand and magnetic disc. Three attempts per...
