Hip dislocation refers to which situation?

• A. Femoral head moves partially out of the acetabulum
• B. Femoral head moves completely out of the acetabulum
• C. The femoral head remains within the acetabulum
• D. There is no displacement

Answer: (B)

Dislocation means the ball-and-socket joint no longer has the two surfaces in contact in their normal position. For the hip, that means the femoral head has completely left the acetabulum and sits out of the socket. That’s what makes it a dislocation rather than a subluxation, where the head is only partially displaced but still largely within the socket. If the femoral head remains inside the acetabulum or there’s no displacement at all, it isn’t a dislocation. So the scenario describing the femoral head moving completely out of the acetabulum is the correct one.
