Clinically relevant finite element technique based protocol to evaluate growing rods for early onset scoliosis correction

The emergence of distraction‐based growing rods has provided the means to reduce the progression of spinal deformity in early onset scoliosis (EOS). The current protocols for evaluating spinal implants (ie, ASTM‐F1717 and ISO‐12189) were developed for fusion/dynamic devices. These protocols do not feature long unsupported rod lengths subjected to distraction. Due to the unsuitability of the existing guidelines for the evaluation of growing rods, a new distraction‐based finite element protocol is presented herein for the first time.
