Anatomic caudal distal radial angle
Anatomic caudal distal radial angle
定义
解剖学桡骨远端尾侧角(aCdDRA)是一种用于评估桡骨成角畸形并为矫正手术提供指导的测量指标。该角度由桡骨的内外侧位X线片或多平面重建CT图像测量获得。
解剖学桡骨远端尾侧角在矢状面内,测量于桡骨远端解剖轴与桡骨远端关节定向线之间。
以下为已报道的解剖学桡骨远端尾侧角均值:
中型及大型犬:78.3 +/- 4.8°(Fox et al. 2006)
小型非软骨营养不良犬:83.08 +/- 3.14°(Duncan et al. 2022)
西施犬:84.27 +/- 1.79°(Jeong et al. 2020)
威尔士柯基犬:59.90 +/- 4.44°(Kwon et al. 2022)
腊肠犬:64.79 +/- 4.43°(Kwon et al. 2022)
北京犬:66.53 +/- 3.59°(Kwon et al. 2022)
马耳他犬:77.59 +/- 4.72°(Kwon et al. 2022)
贵宾犬:71.11 +/- 3.80°(Kwon et al. 2022)
比格犬:75.62 +/- 3.87°(Kwon et al. 2022)
拉布拉多寻回犬:77°(范围 75.9 至 78.0°)(Fox and Tomlinson 2018)
