Anatomic cranial proximal radial angle
Anatomic cranial proximal radial angle
定义
解剖学桡骨近端颅侧角(aCrPRA)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CT图像进行测量。
解剖学桡骨近端颅侧角在矢状面内,测量于桡骨近端解剖轴与桡骨近端关节定向线之间。
目前已报道的解剖学桡骨近端颅侧角均值如下:
中型及大型犬:90.5 +/- 4.0°(Fox et al. 2006)
小型非软骨营养不良犬:87.99 +/- 2.79°(Duncan et al.2022)
西施犬:84.60 +/- 1.46°(Jeong et al. 2020)
威尔士柯基犬:77.62 +/- 5.09°(Kwon et al2022)
腊肠犬:75.69 +/- 4.56°(Kwon et al2022)
北京犬:86.52 +/- 4.13°(Kwon et al2022)
马耳他犬:86.12 +/- 4.65°(Kwon et al2022)
贵宾犬:88.13 +/- 3.91°(Kwon et al2022)
比格犬:84.39 +/- 4.30°(Kwon et al2022)
拉布拉多寻回犬:85°(范围84.1至86.1°)(Fox and Tomlinson 2018)
