Arthroscopically assisted percutaneous fixation of triplane fracture of the distal tibia.

Triplane ankle fractures typically occur in the adolescent age group. Although many are minimally displaced and can be managed nonoperatively, some are displaced and difficult to reduce by closed methods and need open reduction and internal fixation. Traditionally satisfactory articular reduction is achieved through an open approach, which can be extensive. We describe our experience of treating displaced triplane fractures in four patients, assisted by ankle arthroscopy to ensure anatomical reduction and minimal soft tissue disruption. We achieved excellent reduction and stable fixation in all four cases. All patients regained full range of movement within 6 weeks.
