Learning outcomes
  • Assess skeletal radiographs using a systematic approach
  • Use common lines which are helpful in interpreting the image
  • Understand importance of good radiographic positioning
  • Describe tarsal, metatarsal and phalangeal anatomy
  • Understand mechanisms of injury and the likely fractures/dislocations which may result
  • Search for subtle injuries and understand their clinical significance
  • Accurately describe dislocations and associated fractures
  • Understand common eponyms
  • Understand paediatric anatomy
  • Recognise normal variants and their significance (eg, accessory ossicles)
Normal anatomy
Normal foot alignment
Accessory ossicles - Normal variants
Phalanges
Fifth metatarsal fractures
Fracture base 5th metatarsal
Jones fracture
Fracture base 5th metatarsal / normal apophysis
Normal paediatric apophysis   Normal paediatric apophysis   Normal paediatric apophysis
Stress fractures of the metatarsals
Stress fracture, 3rd metatarsal   Subtle stress fracture, 2nd metatarsal
Avulsion injuries of the tarsal bones
Cuboid avulsion fracture
Avulsion dorsal aspect talus, navicular
Avulsion anterior process calcaneum
Avulsion anterolateral calcaneum
Injuries to the anterolateral aspect of the calcaneum may be very subtle but, if missed, can be debilitating:
Missed fracture anterolateral calcaneum - 1st attendance   Missed fracture anterolateral calcaneum  - 2nd attendance   Missed fracture anterolateral calcaneum - follow-up
Lisfranc fracture-dislocation (tarso-metatarsal)
Lisfranc fracture-dislocation   Lisfranc fracture-dislocation
