Posterior collicular fractures of the medial malleolus.
The posterior colliculus of the medial malleolus gives origin to the deep part of the deltoid ligament. Posterior collicular fractures are rare injuries, usually nondisplaced due to stabilization by the tibialis posterior and flexor digitorum longus tendons. This nondisplaced fracture is best identified on external oblique radiographs, which are not usually included in standard ankle views. Thus, some index of suspicion is necessary for their detection. A satisfactory result can be achieved by nonoperative treatment of the posterior collicular fracture.
