Legg-Calve-Perthes Disease In A Child With Osteopetrosis

Osteopetrosis is a rare inherited disorder of bone causing increased bone density. LeggCalve-Perthes disease (LCPD). by contrast, is a more common idiopathic condition leading to variable avascular necrosis of the immature femoral head. We present a case of a 5-year-old boy presenting with these co-morbidities. We have found only one previous reference suggesting these two conditions can coexist in the literature. We discuss the basic principles of management of this interesting case.
