Triplane Fracture of the Distal Fibula.

This is a case report of a 14-year-old girl with a triplane fracture of the distal fibula. The fracture showed displacement and was treated by open reduction, internal fixation, and 5 weeks of external immobilization. The follow-up 5 months after injury yielded an excellent clinical result. Triplane fractures are also seen in locations other than the growth plate of the distal tibia. Due to the occurrence close to the end of the growth period, the potential for growth deformity is negligible. There has been no previous report of a transitional fracture in this location.
