解剖学外侧桡骨远端角(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。该角度通过桡骨的内外侧位X线片或多平面重建计算机断层扫描(CT)图像来确定。

解剖学外侧桡骨远端角定义为在额状面上,桡骨解剖轴桡骨远端关节定向线的交角。

以下为已报道的解剖学外侧桡骨远端角均值:

  • 中型及大型犬:86.7 +/- 2.9°(Fox et al. 2006)

  • 小型非软骨营养不良犬:85.60 +/- 1.74°(Duncan et al. 2022)

  • 西施犬:87.59 +/- 1.37°(Jeong et al. 2020)

  • 威尔士柯基犬:77.63 +/- 4.12°(Kwon et al. 2022)

  • 腊肠犬:76.69 +/- 5.37°(Kwon et al. 2022)

  • 京巴犬:82.95 +/- 3.59°(Kwon et al. 2022)

  • 马耳他犬:87.24 +/- 5.81°(Kwon et al. 2022)

  • 贵宾犬:89.60 +/- 2.03°(Kwon et al. 2022)

  • 比格犬:86.98 +/- 1.58°(Kwon et al. 2022)

  • 拉布拉多寻回犬:86°(范围 85.1 至 86.9°)(Fox and Tomlinson 2018)
