Introduction:
Posttraumatic pediatric distal tibiofibular synostosis is a rare complication of fractures at this level, unreported at this time. Implications include limb length discrepancy, angular malalignment, and gait and biomechanical abnormalities.
Materials And Methods:
The authors present a case report of this complication in a 7-year-old child and review the relevant English literature. The patient was treated for a closed distal tibia-fibula fracture and developed a synostosis at that level, with valgus malalignment of the ankle joint. The synostosis was resected and latest follow-up 16 months postresection showed near normalization of the ankle malalignment. Possible etiologies, the anatomical and functional ramifications, and treatment recommendations for this condition are discussed.
Summary:
Posttraumatic tibiofibular synostosis is a rare complication that has a potential effect on limb length and alignment, both at the ankle and the knee in the skeletally immature patient. Prevention, early recognition, and prompt treatment prevent the anatomic and functional abnormalities that could result from it.
