Mechanical caudal proximal humeral angle
Mechanical caudal proximal humeral angle
定义
机械性尾侧近端肱骨角是用于评估肱骨角度畸形并为矫正提供指导的一种测量指标。该角度由肱骨的内外侧位X线片或肱骨多平面重建图像确定。最佳拟合于肱骨髁内侧和外侧面的圆应同心且不相交。
机械性尾侧近端肱骨角是由以下两者形成的角：
机械性尾侧近端肱骨角的报告均值为：
50.2 +/- 4.5°，来自大型非软骨营养不良成年犬群体（Smith et al. 2017）
43.28 +/- 5.44°，来自大型非软骨营养不良成年犬群体（Wood et al. 2014）
46.75 +/- 2.20°，来自西施犬（Jeong et al. 2020）
