Lateral talar dome
The lateral talar dome may be identified on the lateral aspect of the foot in a similar region to the sinus tarsi. To emphasise the talar dome, place the foot into an inverted and plantarflexed position. A portion of the dome will become prominent laterally. To ensure that you have correctly identified this anatomical feature, evert and invert the foot repeatedly. The dome should reduce with eversion and become prominent again with inversion of the foot.
