Legg Calve Perthes Disease News and Research

Legg-Calvé-Perthes disease is a health condition that involves avascular necrosis of the proximal femoral head. In common language, this refers to damage induced by reduced blood flow to the ball of the thighbone in the hip. This can lead to the death of the bone. As a result, the bone may collapse and become flattened. Over time, the blood supply usually returns and builds up the bone cells again. New bone may eventually replace the old bone over a period of several years.
