Early-onset scoliosis is defined as a spinal curvature greater than 10° in children prior to 10 years of age. Untreated EOS may lead to progressively severe spinal deformity, impaired pulmonary development, restrictive lung disease, and both increased morbidity and mortality. Limitations of established conservative treatments include inability to correct severe deformity, as well as challenges with compliance when casting and bracing is applied. In addition, surgical treatment in the form of traditional growing rods requires regular surgical lengthenings and is associated with complications inherent with repeated invasive procedures and exposure to general anesthesia. MAGEC is an evolving magnetically controlled growing rod system for the treatment of EOS. After initial implantation, lengthening is achieved non-invasively by using magnetic external remote control. MAGEC offers the potential to control moderate and severe EOS, while avoiding repeated surgical procedures and associated complications. In this review, we examine the results from clinical, radiological and explant studies following the use of MAGEC, in the context of other established and emerging treatments for EOS.
早发性脊柱侧弯被定义为10岁前儿童脊柱侧弯大于10°。未经治疗的早发性脊柱侧弯可能会导致脊柱畸形逐渐加重、肺发育受损、限制性肺病以及发病率和死亡率增加。现有保守治疗方法的局限性包括无法矫正严重畸形，以及在应用石膏和支具时存在依从性方面的挑战。此外，传统生长棒形式的手术治疗需要定期进行手术延长，并且与重复侵入性手术和全身麻醉相关的并发症有关。MAGEC是一种用于治疗早发性脊柱侧弯的不断发展的磁控生长棒系统。初次植入后，通过外部磁控远程控制实现非侵入性延长。MAGEC有控制中度和重度早发性脊柱侧弯的潜力，同时避免重复手术及相关并发症。在本综述中，我们结合其他已确立和新兴的早发性脊柱侧弯治疗方法，研究使用MAGEC后的临床、放射学和取出研究结果。
