Abstract
The use of magnetically controlled growing rods (MCGR) has the potential to decrease the morbidity associated with repeated surgeries, yet, strength of the lengthening mechanism as it lengthens may have an impact on the length gained with each lengthening.We evaluated the maximal force generated by MCGR at 3 different lengthened positions and found an average decrease of 0.089 pounds per mm of additional length. This decrease may result in diminished spine length gained with each subsequent MCGR lengthening.
