Description
Injury to tarsal bones or metatarsals including calcaneus, talus, navicular, cuboid, cuneiform, and metatarsals
Etiology
Etiology
- Most common foot injuries are of the metatarsals and phalanges
- The calcaneus is the most commonly fractured of the tarsal bones
- Calcaneus fractures: Compression injury from sudden high-velocity impact to heel:
- 75% are intra-articular; 50% have associated injuries:
- 10% spine fractures
- 25% with associated lower extremity trauma
- 9% bilateral, 5% open
- 75% are intra-articular; 50% have associated injuries:
- Metatarsal fractures: Divided into stress fractures, twisting injuries, or direct trauma:
- First metatarsal: Direct applied force
- Second and third metatarsals are most often involved in stress fractures and twisting injuries
- Fifth metatarsal: Avulsion fracture (dancer's fracture) of proximal apophysis is the most common injury
- Jones fracture: Transverse fracture of the metaphyseal–diaphyseal junction of fifth metatarsal; results from twisting while foot inverted. At risk for nonunion given blood supply only from nutrient arteries
- Talus: Caused by dorsiflexion with axial load, lateral process fx is a common snowboarder's injury
- Navicular: Results from axial compression or stress fractures
- Cuboid and cuneiform fractures are rare and occur in conjunction with other injuries, often with tarsal–metatarsal injuries
- “Nutcracker” compression of cuboid, often related to horseback riding
- Tarsal–metatarsal injuries (Lisfranc injuries) are high-energy injuries:
- Axial load on plantarflexed foot, or hindfoot fixed with forced foot eversion
- Unstable forefoot on hindfoot
- 20% go undiagnosed on initial visit
- 3 types: Convergent, divergent, and incongruent
Pediatric Considerations
- Metatarsal fractures account for 90% of foot fractures in children, usually from direct trauma:
- Lesser metatarsal fractures (2–4) most common, followed by base of fifth, then base of first metatarsal
- Physeal injury may occur with proximal first metatarsal fractures
- Other common injuries include phalangeal fractures (17%) and navicular fractures (5%)
- Fractures of talus or calcaneus occur with distal tibia or fibula fractures (8%)
- Calcaneus fractures are less likely intra-articular. Less common to have associated spine fractures
