Sections:
The talocrural angle can be used to assess for fibular shortening after a fracture.
Measurement
The talocrural angle is measured on the mortise view as the angle between a line along the distal tibial plafond articular surface and another line joining the tips of both malleoli 3,4.
Interpretation
- normal: 83° ± 4° 2 or 8-15° 3
- fibular shortening: >2° difference to the contralateral side 2
