BackgroundTo identify the fracture configuration and treatment results for patients with triplane and Tillaux fractures in the ankle joint.MethodsA retrospective study was performed on 14 patients with a more than one year follow-up. This study investigated the fracture configuration, concomitant fibula fracture, treatment methods and complications. The treatment outcomes were analyzed using modified Weber protocol.ResultsAmong the 14 cases, 11 were triplane fractures and 3 were Tillaux fractures. Seven were two part triplane fractures, and 4 were three part triplane fractures. Eight were lateral triplane fractures, and 3 were medial triplane fractures. A fibula fracture was accompanied by 7. The fibular fracture comprised of oblique fractures in all cases. A closed and open reduction was performed in 6 and 8 cases, respectively. All but one showed excellent treatment outcomes at the final follow-up. Traumatic arthritis developed in 1 case.ConclusionsPrecisely detecting the fracture configuration by computed tomography and understanding the injury mechanism have greatly improved the outcomes of triplane fractures and Tillaux fractures of the ankle in adolescent patients.
