Diagnosis of Fractures
The ankle is a structure of three bones (tibia, talus and fibula) linked by three ligaments (the medial and lateral collateral ligaments and the interosseous ligament). A break in one part of the ring is likely to result in a second break elsewhere.
The second break may be either another fracture or ligamentous damage.
AP mortice view
Inspect :
The joint space. It should be traced from the medial side, over the superior aspect of the talus, to the lateral side of the joint. This space should be uniform all the way rouns.
The integrity of the talar dome
Lateral view:
Inspect:
The lateral and medial malleoli. The lateral malleolus extends more inferiorly than the medial malleolus.
The posterior aspect of the tibia - sometimes called the posterior malleolus.
The calcaneum. A calcaneal fracture may occasionally result from an apparently simple twisting injury.
The fifth metatarsal. It is common for an inversion injury to cause an avulsion fracture at the base of the metatarsal.
