Congenital hip dysplasia, or developmental dysplasia of the hip, is a problem where the socket or acetabulum - and the femoral head are misaligned, resulting in an unstable hip joint.
Typically, the problem is present at birth, but sometimes it appears later as the bones develop over time.
The hip joint is a ball and socket type because the ball-shaped head of the femur sits and rotates within the acetabulum which is a cup-shaped socket.
The hip joint is supported by a tough fibrous joint capsule, which is made up of three main ligaments, the iliofemoral, the pubofemoral, and the ischiofemoral.
The main job of the joint capsule is to hold articulating bones together and make sure the joint stays stable when the hip is moving.
Now, the acetabulum itself is a combination of parts of three pelvic bones that join together - the ischium, the ileum, and the pubis.
At the bottom of the acetabulum known as the acetabular fossa, arises a ligament, called the ligamentum teres that attaches to the fovea capitis, which is a depression found on the tip of the femoral head.
This ligament helps with joint stability especially during hip flexion and abduction.
Now, the edge of the acetabulum has a thick bony circular rim covered by a ring of cartilage known as the acetabular labrum.
At its lower end, there’s a depression called the acetabular notch, which is covered by the transverse ligament which fills the gap within the circumference of the acetabulum.
