概括

前置释放手术改善了严重青少年异常学脊椎病 (AIS) 曲线中脊柱形的纠正,特别是当手术前显著减少3D胸部形时. 这种方法适用于超过70度的曲线.

科学领域:

脊柱外科手术脊柱外科手术
整形外科整形外科整形外科
生物机械分析分析

背景情况:

大型胸部曲线 (≥70°) 的青少年异常学脊椎病 (AIS) presents显著的外科手术挑战.
优化手术技术以最大限度地纠正曲线和脊柱对齐至关重要.

研究的目的:

在大型AIS曲线中评估前部释放 (椎间盘切除) 的直接术后影响.
用3D变形分析来定义前部释放的指示.

主要方法:

对AIS患者的回顾性多中心研究,胸部曲线≥70°.
前/后 (AP) 与仅仅后部的外科手术方法的比较.
使用定制软件分析2D和3D放射性参数,包括3D胸部形 (3DTK).

主要成果:

AP组的曲线更大,更不灵活,但实现了更高的百分比校正.
AP手术导致了类似的术后曲线大小,但3DTK的显著改善.
术前3DTK<-18°需要前部释放才能达到术后3DTK>25°.

结论:

前部释放与后部仪器相结合,在严重的AIS (>70°) 中改善了冠状和斜的纠正.
3D分析强调前部释放有助于改善胸部形,特别是在术前显著的形变形的情况下.
前部释放的指示应考虑手术前的3D胸部位值.

关键词:

Vertebral Column: Regions and Curvature

Vertebral Column: Regions and Curvature

The vertebral column or spine is a flexible column that supports the head, neck, and body and allows for their movements. It also protects the spinal cord.
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form...
