Question

Quizplus · Accepted Answer

Congenital hip dysplasia is a condition in which there is a malformation of the acetabulum (the cup-shaped socket of the hip joint) causing displacement of the femoral head (the ball-shaped end of the thigh bone). Osteopetrosis and Paget's disease are not associated with hip dysplasia, and Legg-Calvé-Perthes disease involves avascular necrosis of the femoral head, rather than displacement.
