Vertebral Body Tethering |Overview
椎体约束是什么?
椎体系列（VBT）is a surgical treatment for特发性脊柱侧凸在生长的儿童中，尽管仍在继续进展的儿童支撑。The treatment wasapproved by the FDAin August 2019.
这种“生长调制”处理使用锚和连接的柔性绳索，以将脊柱引导成作为儿童增长的直立对齐。可以使用椎体系列代替脊柱融合手术对于一些具有特发性脊柱侧凸的孩子。
椎体如何抚养工作？
椎体束缚利用脊柱的天然生长，以纠正横向曲率，同时允许脊柱继续生长。
Surgeons attach metal anchors to the vertebrae on the side of the spine that curves outward. A flexible cord, called a tether, is connected to these anchors and placed under tension. Over time, as the child continues to grow and their spine lengthens, the tether slows the growth on the curved side of the spine. This allows the other side of the spine to catch up. Over time, as a child grows, the spine grows straighter.
The anchors and tether will remain attached to child’s spine permanently unless problems develop.
椎体束缚和脊柱融合手术有什么区别？
与脊柱融合手术相比，椎体系束性允许更大的脊柱迁移率和柔韧性。由于名称暗示，脊髓融合手术后，受影响的椎骨融入固体骨。在手术时，这部分脊柱不会弯曲或长出其高度。
Vertebral body tethering preserves the flexibility of the spine and allows for continued growth.
椎体束缚是一种新的治疗，已经显示出现早期结果。但是，长期成功率尚不清楚。几十年来，外科医生已经进行了成功的几十年的脊髓融合手术。
椎体是我孩子的选择吗？
椎体束缚是某些具有特发性脊柱侧凸的儿童的手术选择，其脊柱曲线与支撑或不能忍受支撑的脊柱曲线。
经过彻底的考试和病史后，我们的外科医生将与您讨论各种治疗方案的优缺点。关于VBT的以下事实将有助于确定它是否是您孩子的选项：
- 因为VBT通过引导脊柱的生长来纠正脊柱侧凸，因此对于尚未达到成熟高度的儿童而言，它只有效。
- Children must have strong enough bones to support the anchors that will be attached to their spines.
- 虽然每个孩子都不同，但大多数经过此程序的孩子均在8和16岁之间。
- Children with curves less than 45 degrees are at risk of overcorrection (spine curves in the opposite direction) with this procedure.
- 该过程在大于65度的曲线上没有那么有效。
- 椎体束缚主要针对具有特发性脊柱病的儿童与神经病症或其他畸形或损伤无关。
How soon will my child be able to return to school and sports after vertebral body tethering?
Typically, children stay overnight at the hospital for two to three days after vertebral body tethering. Many return to school one to three weeks after the procedure and return to normal activities after six weeks.
