Distal tibial joint orientation line
Distal tibial joint orientation line
定义
远端胫骨关节定向线是用于评估胫骨成角畸形并为矫正提供指导的解剖标志。它由胫骨的X线片或多平面重建CT图像确定。
额状面
进行X线评估时，犬取背卧位或腹卧位，拍摄颅尾位或尾颅位X线片：视野包括胫骨全长、膝关节和跗关节。胫骨与射线束垂直，射线束以胫骨骨干中段为中心。
远端胫骨关节定向线是连接胫窝，胫骨窝的内侧沟与外侧沟软骨下骨最近端点的连线。
矢状面
进行X线评估时，犬取侧卧位，拍摄内外侧位X线片：视野包括胫骨、膝关节和跗关节；射线束以胫骨骨干中段为中心，膝关节与跗关节均屈曲90°。
