The sagging rope sign is the term used to describe the radiographic appearances which sometimes occur after Perthes' disease. It is severe examples of that disease and indicates damage to the growth plate with a marked metaphysial reaction. The same appearance follows severe epiphysitis after forcible reduction of a congenitally dislocated hip, and certain rare epiphysial dysplasias. The origin and significance of the sign are discussed.
