The language spoken by orthopedic surgeons is filled with eponyms. In orthopedics, perhaps more than in any other medical specialty, we speak cryptically to one another using these code words and other secret language. Certain hyphenated eponyms are of particular interest because they simulate one's curiosity as to how these people came to be linked in orthopedic history. In this article, we offer some bits of orthopedic "hyphenated history," outlining the pertinent work of Henry Albert Harris and Edwards Albert Park, as well as other associated background information. These physicians are linked through a common hyphenated eponym in orthopedics--Park-Harris growth arrest lines.
