was changed:
The lateral talocalcaneal angle is one of the angles that can be measured for the assessment of pes planus and pes cavus and assessment of hindfoot deformity.
Measurement
The lateral talocalcaneal angle is drawn on a weight-bearing lateral foot radiograph as . There are two ways that it has been defined 2:
- the angle between the calcaneal inclination axis and the mid-talar axis
and - the angle between the lines bisecting the longitudinal axis of the two bones
The calcaneal inclination axis is generally more easily measured than the longitudinal axis of the calcaneus. It tends to be steeper and therefore the angle measured against the calcaneal inclination axis will be greater than using the mid-calcaneal axis.
Interpretation
The lateral talocalcaneal angle should normally measure between 35-5025 and 40°:
- <
;35;25° - >
;50;40°
