This study reports a novel stress radiography technique to evaluate an avulsion fracture at the lateral malleolus in children. Radiographs in the stress anteroposterior view or the Haraguchi calcaneofibular ligament or anterior tarofibular ligament (ATFL) projection could not detect any fracture; only manual inversion stress radiography in the Haraguchi ATFL projection could identify the avulsion fracture.
