To the best of our knowledge, this is the only report of partial ECU subluxation due to a split in the ECU tendon presented in the literature. This case illustrates the importance of proper diagnosis and treatment of such a lesion. We also emphasize that dynamic ultrasound is an excellent and cost-effective imaging modality that can help with the diagnosis of partial ECU subluxation. Finally, surgical treatment for failed conservative management showed excellent results in an elite athlete. Copyright © 2017 Wolters Kluwer Health, Inc. All rights reserved.
