Exact figures for this condition are not known, but it is thought that around 1 in every 2000 children is affected. Perthes’ disease occurs in the 2–12-year age group, but most cases are seen between the ages of 4 and 8 years. Boys are about four times more frequently affected than are girls. A few of the children with Perthes’ disease have the condition in both hips. Whilst there is no discernible genetic link, brothers and sisters of sufferers have a slightly higher chance of having the condition than does the general childhood population.
