A little while back I discussed Lisfranc fractures of the foot. Here is an image depicting a fracture-dislocation through the Lisfranc joint:
This one is not subtle! You can see that the bases of metatarsals 1-5 are laterally dislocated. Remember, the Lisfranc joint involves articulation between metatarsals and tarsus (navicular, cuboid, and three cuneiform bones). A Lisfranc fracture occurs when one or more of the metatarsals are dislocated from the tarsus.
As a reminder of the Lisfranc radiology findings here is a Word® document reminding us of the “Radiology Rules.” It is in 3X5 card format you can print front and back and have a convenient reminder if you want to carry it with you on your clinical shifts. That way hopefully we won’t miss the subtle ones…
