The mid-talar axis represents a line drawn down the longitudinal axis of the talus and can be drawn on lateral and DP radiographs.
- lateral view: line should bisect the shaft of the first metatarsal
- DP view: line should intersect (or pass just medial to) the base of the first metatarsal
It can be used to measure:
Lower limb radiography
- standard foot radiograph series
