Stress fractures of the second metatarsal involving Lisfranc's joint in ballet dancers. A new overuse injury of the foot
LJ Micheli, RS Sohn and R Solomon
We reviewed the cases of four female ballet dancers with a stress fracture
of a type that has not been reported previously. This fracture occurs in
the proximal portion of the second metatarsal and involves the volar and
medial aspects of Lisfranc's joint. A differential diagnosis of pain in the
middle part of the foot in a dancer should include a consideration of this
entity, which can be very difficult to diagnose on initial assessment.
Oblique radiographs, tomograms, and a bone scan may be necessary to confirm
the diagnosis. With early recognition and diagnosis, in three of the four
patients the fracture healed with immobilization and modified training. One
patient required surgical resection because of persistent non-union of the
necrotic fracture fragment.
