The adolescent pilon fracture: management and outcome.

ABSTRACT

Pilon fractures in the adolescent are complicated by the presence of the adjacent physis. These fractures usually result from high-energy trauma, frequently associated with soft-tissue trauma, further potentiating treatment difficulties. Although rare, such fractures are associated with a high complication rate, including physeal arrest. It was the objective of this review to increase awareness of this fracture pattern in the adolescent, to determine the types of complications in this difficult group, and to develop a treatment plan to improve the outcome of treatment. Seven children, with a total of eight pilon fractures were treated at a major pediatric tertiary referral center over the past 10 years. The average age of the children was 15 years 10 months (range, 13 years 6 months to 17 years 7 months). The average length of follow-up was 16 months (range, 3 months and 3 years 10 months). There were three Reudi type II equivalent fractures and two Reudi type III equivalent injuries. Three fractures did not fit the Reudi classification system as there was an associated ankle dislocation. All fractures were treated with open reduction and internal fixation. There were two cases of posttraumatic osteoarthritis and one physeal arrest. Results were good to excellent in 63% of cases. A new classification system for pediatric pilon fractures has been proposed.
