Bilateral tibial tubercle avulsion fractures: A pediatric orthopedic injury at high risk for compartment syndrome.

Adolescent tibial tubercle avulsion fractures represent an uncommon, but clinically significant condition for emergency medicine physicians. Early recognition of the signs and symptoms of this pediatric orthopedic diagnosis are important, as anterior compartment syndrome can occur in up to 10-20% of cases. Anterior tibial tubercle fractures are generally sport related injuries, occurring primarily in otherwise healthy adolescent males between the ages of 11-17. They account for less than 3% of all epiphyseal injuries in this age group and are rarely bilateral in nature. In this article, we present a case with two unique clinical features: bilateral sports related tibial tubercle avulsion fractures and subsequent development of bilateral clinical compartment syndrome. We briefly review the risk factors, presentation, and diagnosis of this rare but clinically important condition. Published by Elsevier Inc.
