MAGEC rods (NuVasive) provide distraction growth in early-onset scoliosis. Pedicle screw use with MAGEC rods can lead to anchor failure. Sublaminar bands offer superior fixation points for the MAGEC system while preserving pedicles and facets, avoiding spinal cord injury, and eliminating the need for fluoroscopy. Sublaminar bands can be safely used up to cervical vertebra four (C4), substantially decreasing the risk of complications such as anchor pull-out, rod breakage, and proximal junctional kyphosis that typically occurs with pedicle screws and hooks. This case demonstrates the viable option of sublaminar band fixation as an anchor system for MAGEC rods. This is a retrospective case review of one patient with early-onset scoliosis who underwent multiple osteotomies, spinal cord decompression, and placement of MAGEC rods with sublaminar bands. The patient had successful distraction procedures conducted routinely throughout a 44-month period with no associated implant complications or neurologic sequelae during that period. The patient had achieved maximal distraction with the implanted rods and thereafter underwent removal of the MAGEC rods and replacement implantation with longer MAGEC rods. The purpose of this case review was to demonstrate the superior fixation results provided with sublaminar band fixation for MAGEC rod distraction systems.
MAGEC 棒（NuVasive）可提供早期脊柱侧凸的生长分离。MAGEC 棒与椎弓根螺钉的使用可能导致锚定失败。 皮下带为 MAGEC 系统提供了更优越的固定点，同时保留了椎弓根和关节突，避免了脊髓损伤，并消除了透视的需要。皮下带可以安全地用于 C4 颈椎，大大降低了通常与椎弓根螺钉和钩子相关的并发症风险，如锚钉拔出、棒断裂和近端交界性后凸。 该病例展示了皮下带固定作为 MAGEC 棒锚定系统的可行选择。这是一名患有早期脊柱侧凸的患者的回顾性病例报告，该患者接受了多次截骨术、脊髓减压和 MAGEC 棒皮下带固定。在 44 个月的时间内，患者成功地进行了常规的分离手术，在此期间没有出现与植入物相关的并发症或神经后遗症。患者通过植入的棒获得了最大的分离，此后进行了 MAGEC 棒的移除，并更换为更长的 MAGEC 棒。本病例回顾的目的是展示皮下带固定在 MAGEC 棒分离系统中的固定效果。
