解剖学内侧桡骨近端角(anatomic medial proximal radial angle,aMPRA)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线片或桡骨的多平面重建CT图像测定。

解剖学内侧桡骨近端角定义为额状面上桡骨解剖轴桡骨近端关节定向线的交角。

以下为已报道的解剖学内侧桡骨近端角均值:

  • 中型及大型犬:85.3 +/- 3.5°(Fox et al. 2006)

  • 小型非软骨营养不良犬:80.86 +/- 2.86°(Duncan et al. 2022)

  • 西施犬:85.04 +/- 1.58°(Jeong et al. 2020)

  • 威尔士柯基犬:70.53 +/- 4.49°(Kwon et al. 2022)

  • 腊肠犬:70.96 +/- 4.49°(Kwon et al. 2022)

  • 北京犬:61.97 +/- 5.30°(Kwon et al. 2022)

  • 马耳他犬:73.51 +/- 4.83°(Kwon et al. 2022)

  • 贵宾犬:77.91 +/- 3.44°(Kwon et al. 2022)

  • 比格犬:74.82 +/- 1.87°(Kwon et al. 2022)

  • 拉布拉多寻回犬:83°(范围81.7至83.3°)(Fox and Tomlinson 2018)
