Proximal tibiofibular joint dislocation: a rare entity.

A 37-year-old woman was diagnosed with an isolated proximal tibiofibular joint dislocation (PTJD) after an accident during gymnastic exercise. The dislocation has a low incidence rate and is often missed in the emergency department as physical and radiology signs are subtle. Treatment consists of closed or open reduction and immobilisation. When it is not recognised it is associated with significant peroneal nerve injury.
