Magnetic controlled growing rods (MCGRs) are one of the most common procedures to treat early-onset scoliosis (EOS). One of the major concerns is that patients treated with MGCR do not reach an adequate height with MGCR. The present study has one of the largest sample sizes of EOS patients treated by MGCR. This study aims to demonstrate the efficacy of the treatment with MGCR in EOS patients, comparing our results with the estimated growth.
Patients were consecutively enrolled from July 2011 to July 2022. The same surgical equipe performed all the procedures. The mean length of the patients was assessed by X-ray (T2-T12 and T2-S1 distance) by a team of expert radiologists. The estimated growth by Dimeglio was compared with the mean elongation obtained by year.
65 patients were included. 16 patients underwent final surgery. In group 1, patients reached a growth of 3.6 ± 8.7 mm (T2-T12) and 9.6 ± 27.6 mm (T2-S1). In group 2, patients grew 5.4 ± 5.7 mm (T2-T12) and 9 ± 9 mm (T2-S1).81% of the estimated elongation during the treatment was obtained during the first surgery. The difference between Dimeglio's estimated growth and the value obtained by MGCR was -4.3 ± 8.7 mm(T2-T12) and -12.3 ± 12.2 mm (T2-S1) in group 1 (p < 0.001) and -1.1 ± 4.2 mm (T2-T12) and -6.6 ± 6.0 mm (T2-S1) in group 2 (p = 0.001).
MGCR patients reached and overlapped the growth target according to the score by Dimeglio. However, the value of growth tended to reduce over the years. Lastly, obtaining the most significant elongation possible at the first surgery is mandatory, comprising 81% of the total value.
磁控生长棒（MCGR）是治疗早发性脊柱侧凸（EOS）的常用方法之一。其中一个主要问题是，接受 MCGR 治疗的患者无法通过 MCGR 达到足够的身高。本研究是接受 MCGR 治疗的 EOS 患者中样本量最大的研究之一。本研究旨在证明 MCGR 治疗 EOS 患者的疗效，将我们的结果与估计的生长进行比较。
患者于 2011 年 7 月至 2022 年 7 月连续入组。同一手术团队进行了所有手术。由一组专家放射科医生通过 X 射线（T2-T12 和 T2-S1 距离）评估患者的平均长度。通过 Dimeglio 估计的生长与每年获得的平均伸长量进行比较。
共纳入 65 例患者。16 例患者接受了最终手术。在第 1 组中，患者的 T2-T12 生长 3.6±8.7mm，T2-S1 生长 9.6±27.6mm。在第 2 组中，患者的 T2-T12 生长 5.4±5.7mm，T2-S1 生长 9.0±9mm。81%的估计伸长在第一次手术期间获得。Dimeglio 估计的生长值与 MCGR 获得的值之间的差异在第 1 组中为-4.3±8.7mm（T2-T12）和-12.3±12.2mm（T2-S1）（p<0.001），在第 2 组中为-1.1±4.2mm（T2-T12）和-6.6±6.0mm（T2-S1）（p=0.001）。
MCGR 患者达到并超过了 Dimeglio 评分的生长目标。然而，生长值随着时间的推移趋于减少。最后，在第一次手术中获得尽可能大的伸长量是强制性的，占总价值的 81%。
