The fishtail deformity of the distal humerus is a rare entity that most often develops as late sequela of a pediatric elbow fracture. The observed morphologic changes that define this diagnosis have been attributed to vascular compromise of the lateral trochlea and subsequent resorption or failure of development of the trochlear ossification center (dependent upon the skeletal maturity of the patient at time of initial injury). The purpose of this exhibit is to demonstrate the imaging features that will allow radiologists to confidently diagnose a fishtail deformity of the distal humerus and to understand the pathogenesis behind the morphologic appearance. We will also discuss prognosis and management, knowledge that will allow the radiologist to be of additional value in multidisciplinary discussions. Read More
