Mechanical caudal distal tibial angle

The mechanical caudal distal tibial angle is a measurement used to assess angular deformities of the tibia and provide guidance for corrections. Is determined from a mediolateral radiograph or a multiplanar reconstructed CT images of the entire tibia. For radiographic evaluation, the dog is positioned in lateral recumbency and a mediolateral radiograph is taken: the view includes the tibia, the stifle joint and the tarsal joint: the beam is centered on the mid-tibial diaphysis with the stifle and tarsus joints both at 90° flexion.

The mechanical caudal distal tibial angle is the angle between the mechanical tibial axis and the distal tibial joint orientation line, at the caudal aspect fo the tibia.
