There are 26 bones in the foot and potentially all of them can be traumatised through a direct impact injury, falling over, inappropriate biomechanics or overuse. Whereas some fractures are easy to identify (displaced fractures), others are more difficult to detect. Avulsion fractures (e.g. anterior process of calcaneum, tip of fibula) tend to need a different treatment than complete fractures through the central aspect of the bone. Intra-articular (affecting the joint) fractures may need more attention than extra-articular fractures. Some bones have a very good healing potential (eg.calcaneum) whereas other need a long time to consolidate or are at risk of not healing properly (talus). Some fractures are more likely to be stable whereas others may need more protection to heal uneventfully.
