Pediatric Maisonneuve and Tillaux Fractures with Lateral Ankle Dislocation: A Pediatric "Logsplitter" Injury: A Case Report.

CASE: A 12-year-old adolescent boy presented with a proximal fibula fracture and lateral ankle dislocation consistent with a Maisonneuve fracture (MF) associated with a transsyndesmotic ankle dislocation. The dislocation was reduced under conscious sedation in the emergency department. Postreduction imaging studies demonstrated a Tillaux fracture. The patient underwent surgical stabilization of the Tillaux fragment and of the distal tibiofibular syndesmosis. At the 26-month follow-up, the patient remained active without restrictions. CONCLUSION: Operative treatment of a concurrent MF, Tillaux fracture with lateral ankle dislocation, or a pediatric "logsplitter" injury resulted in satisfactory alignment and function of the ankle joint.
