概括

骨盆角C7 (C7PA) 与青少年异常脊柱病患者的脊骨平衡有很强的相关性. 手术前的C7PA低于0.3倍的骨盆倾斜,表明手术后骨盆发病率与腰椎位不匹配的风险更高.

科学领域:

整形外科整形外科整形外科
脊柱外科手术脊柱外科手术
放射学放射学是一门学科.

背景情况:

青少年异常学脊椎病 (AIS) 涉及复杂的脊柱形.
脊椎骨盆参数对于评估斜腰平衡至关重要.
选择性胸部融合 (STF) 旨在纠正冠状元形,同时保持形对齐.

研究的目的:

分析C7骨盆角 (C7PA) 与Lenke 1和2 AIS中的其他脊骨骨盆参数之间的关联.
为了评估C7PA对盆腔发病率 (PI) - 腰部病 (LL) 的预测值,STF后的不匹配.

主要方法:

对Lenke 1/2 AIS接受STF的106名患者进行了回顾性研究.
对脊椎皮层参数的相关性和ROC曲线分析.
多变量后勤回归用于识别PI-LL不匹配的风险因素.

主要成果:

在手术前和手术后,C7PA与PI-LL有很强的正相关性 (r=0.736和r=0.903).
在手术前的C7PA ≤0.3 ×骨盆倾斜 (PT) 显著增加了PI-LL不匹配的风险 (OR=6.38,p=0.005).
(0.3×PT - C7PA) 在预测PI-LL不匹配方面表现出最高的AUC (0.745).

结论:

在接受STF的AIS患者中,C7PA是脊骨皮层对齐和PI-LL结果的关键指标.
与PT相对的术前C7PA是术后PI-LL不匹配的关键预测因素.
这一发现有助于在手术规划中优化脊柱脊柱直后的斜腰平衡.

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...
