Q

Acetabular dysplasia

Q

Sublaxation

A

the largest percentage of DDH, incomplete dislocation of the hip. The femoral head remains in contact with the acetabulum, but a stretched capsule and ligamentun teres causes the head of the femur to be partially displaced. Pressure on the cartilaginous roof inhibits ossification and produces a flattening of the socket.
