Bilateral Perthes' Disease

Abstract

Bilateral Perthes' disease is defined as the form of the condition where radiological changes affect both hips simultaneously. the radiological abnormalities are commonly more severe on one side than on the other. in a small proportion of patients a clear time interval exists between the onset of radiological changes in the two hips. It is suggested that this form of the condition is two unilateral and separate attacks of Perthes' disease and it is more akin to 'recurrent' Perthes' disease.

Key Words:

• Perthes' disease
