Eponyms, while inherently flawed, remain a constant in medical vernacular, especially in orthopaedic surgery. It is essential to understand how these eponyms came to be named and for whom they were named after in order to know the correct usage and definition of these eponyms. In this first part, we describe the history of eponym usage in paediatric hip radiography; who, when, what, where, and how. We hope to provide a historical perspective of interest, resolve any controversies in semantic definitions, and create a comprehensive library of eponymous terms related to paediatric hip radiography.
