Fractures of internal (second, third, fourth) metatarsals are very common. Nondisplaced and displaced fractures usually heal well, with weight bearing as tolerated, in a cast or rigid flat-bottom orthopedic shoe. In fact, data suggest that elastic support bandages are equivalent or superior to casts for such metatarsal fractures. [26] Exclude disruptions of the Lisfranc (tarsometatarsal) joint by maintaining a high level of suspicion.

March fracture is a stress fracture of the second and/or third metatarsal that commonly occurs in joggers. Radiographs are often negative, and sometimes a bone scan helps determine this diagnosis. Treatment is cessation of aggravating activity for 4-6 weeks.
