Legg–Calvé–Perthes disease (LCPD) is a hip disorder caused by a disruption of blood flow to the femoral head. Lack of an adequate blood supply causes the head of the femur to die. This condition is rare and affects only children.

Avascular necrosis, or osteonecrosis, is a condition where bone tissue dies from lack of blood supply. Without enough blood, small breaks begin to form in the bone and potentially cause disintegration. While anyone can develop this condition, it typically occurs in middle-aged adults between the ages of thirty and sixty. If treated early enough, further bone damage can usually be minimized through home treatment and therapy; surgery is a last resort. (Mayo Clinic)
While most people who have hip dysplasia are born with the condition, it is possible to develop later in life. In most cases, patients of hip dysplasia experience relief after a few months of at-home treatment and therapy.
Causes, Symptoms, & Risk Factors
Hip dysplasia is most commonly a result of the ball joint of the hip being moved out of place while in the womb. Even during the early stages of development, the ball and the socket rely on each other in order to form correctly. During the final trimester, the womb may become so cramped that the ball joint shifts from the socket, causing dysplasia. (American Academy of Orthopaedic Surgeons)
