Anterior collicular fractures typically result from supination external rotation mechanisms and appear as a transverse oblique fracture on the AP (anterior-posterior) view.
Tornetta (24) showed that fixation of anterior collicular fractures does not necessarily confer medial stability to the ankle.
Posterior collicular fractures begin in the intercollicular groove and extend superiorly and posteriorly.
In this case, the peripheral cue would automatically activate a collicular local motor program for a saccade in the direction of the stimulated position.
