Osteochondroma Involving the Hip

Abstract

The hip joint is a common site of symptoms in Multiple Osteochondromatosis (MO), but is infrequently involved by solitary exostoses. In young children with MO, coxa valga is characteristic; features of hip dysplasia occurs in less than 50% of individuals and are usually mild. In older children, hip impingement - either extracapsular or intracapsular - is a common feature and is managed according to symptoms, anatomical location and the extent of osteochondromatosis. Hip joint subluxation is an urgent problem requiring surgical intervention. Malignant change is very rare in the first two decades of life.
