The aim of the study was to develop new equipment for the assessment of the flexibility of the spine with different forces. This new system should provide a different perspective to adolescent idiopathic scoliosis (AIS) for the selection of fusion levels and surgical success.
Eighteen patients suffering from AIS who were scheduled to undergo posterior instrumented spinal fusion in our clinic were recruited in this study. The Electronic Traction Table (ETT) that was designed in our clinic was used to evaluate the radiogical and clinical parameters of the spine.
The significant prescriptive angle of major Cobb angles between postoperative angles were longitudinal traction and lateral pushing Cobb angles. Longitudinal traction and lateral pushing angles were more correlated with correction ratios. There was a significant difference between longitudinal traction minor Cobb angle, longitudinal traction lateral pushing minor Cobb angle and postoperative minor Cobb angles.
The deformity is needed to balance both tractional and rotational forces and useful technique to evaluate curve flexibility before the operation. Electronic traction table is a new device for determining preoperative flexibility with longitudinal traction and lateral pushing radiographs. It can be useful for choosing selective fusion levels at the proximal and distal end of the vertebral column.
本研究的目的是开发用于评估不同力量下脊柱柔韧性的新设备。这种新系统应为青少年特发性脊柱侧凸（AIS）选择融合节段和手术成功率提供不同的视角。
本研究招募了18例计划在我院接受后路器械脊柱融合术的AIS患者。使用我院设计的电子牵引床评估脊柱的影像学和临床参数。
术后角度之间主要Cobb角的显著规定角度为纵向牵引和侧向推挤Cobb角。纵向牵引和侧向推挤角度与矫正率的相关性更高。纵向牵引小Cobb角、纵向牵引侧向推挤小Cobb角与术后小Cobb角之间存在显著差异。
在手术前，需要平衡牵引和旋转力以矫正畸形，并且这是评估曲线柔韧性的有用技术。电子牵引床是一种通过纵向牵引和侧向推挤X线片来确定术前柔韧性的新设备。它可有助于选择脊柱近端和远端的选择性融合节段。
