talonavicular coverage angle
Measurement
of the talonavicular coverage angle as part of the workup of flat feet.
The talonavicular coverage angle reflects the degree of, if any, talonavicular lateral subluxation. On DP weight-bearing foot radiographs, it is the angle between:
- articular surface of the talar head
- articular surface of the proximal navicular
Interpreting the talonavicular coverage angle:
- normal: <7°
- adult acquired flatfoot disease: >7°
