Background
Approximately 10% of all fractures occur in the 26 bones of the foot. These bones comprise 2 bones in the hindfoot (calcaneus, talus), 5 bones in the midfoot (navicular, cuboid, 3 cuneiforms), and 19 bones in the forefoot (5 metatarsals, 14 phalanges). In addition, the foot contains sesamoid bones, most commonly the os trigonum, os tibiale externum, os peroneum, and os vesalianum pedis. Their smooth sclerotic bony margins and relatively consistent locations help distinguish them from fractures. Hindfoot connects to the midfoot at the Chopart joint; forefoot connects to the midfoot at the Lisfranc joint.
Below is an example of a common fracture.
Fractures, foot. Proximal fifth metatarsal avulsion fracture (also termed pseudo-Jones, tennis, or dancer fracture). Epidemiology
Age
In contrast to adults, children have relatively stronger ligaments than bone or cartilage. As a result, fractures are more common than sprains in children. However, a child's forefoot is flexible and resilient to injury. When metatarsal or phalangeal fractures do occur, they may be difficult to recognize because of multiple growth centers. In such cases, comparison views of the uninjured foot often are helpful. Persistent foot pain in children should raise the physician's concern for potentially important fractures, even in the absence of plain radiographic signs.[1]
