þ Lisfranc Fracture-Dislocation:
 - Fracture/dislocation at tarso-metatarsal junction.  Subtle findings on
   x-ray, so easy to miss.  Best clue is widening of separation between first
   and second metatarsals.  Also look for small avulsion fractures from the
   medial base of the second or lateral base of the first metatarsal.

 - Classic mechanism:  Fall from horse with foot still in stirrup.  
   To test for tarsometatarsal or
   talonavicular instability:  stress x-rays with foot inverted and everted,
   or weight-bearing lateral films.

þ Fifth Metatarsal Fractures
 - Can use Reese shoe instead of cast shoe; slightly less clumsy.
