C. CAPT 1/7 BATTALION/ WORCESTERSHIRE REGT/ 2ND SON OF LEWIS ALEXANDER/ AND MABEL KATE WALLACE/ OF HAWFORD HOUSE/ CLAINES/ KILLED IN ACTION IN FLANDERS/ AUG. Since 2015, various other modifications have been made to allow a smaller sized actuator (70 mm) for smaller children, and reinforcement of the actuator pin [ 24]. Mechanical failures include spontaneous bone formation near the housing unit, actuator pin fracture [ 24], and rod stalling/clunking. Use of magnetic spinal growth rods (MCGR) with and without preoperative halo-gravity traction (HGT) for the treatment of severe early-onset scoliosis (EOS).

This is observed around the rod-anchor junction and extendable portion of the MCGR in patients undergoing revision surgery [ 29]. Growing rods are now the standard treatment option for EOS because it prevents curve deterioration while accomodating physiological spinal growth [ 1, 2, 3]. The MCGR and its surgical technique have gone through many iterations to solve various problems exhibited by this patient’s journey.

Dual growing rod technique followed for three to eleven years until final fusion: the effect of frequency of lengthening.
