What The Referring Physician Needs To Know- Tarsometatarsal or Lisfranc injuries may be subtle and complex; radiographs may demonstrate subluxation, dislocation or fracture
- Up to 20% of Lisfranc injuries are overlooked on initial radiographs
- If radiographs are equivocal, CT should be obtained to exclude subtle mid foot fractures
- Injuries with no evidence of instability on weight bearing can be managed with closed reduction and cast immobilization
- Open reduction and internal fixation is sometimes required (Fig. 20, Fig. 21, Fig. 22, Fig. 23)
- Fusion of fourth and fifth metatarsal bases should be avoided where possible
