Final answer:
A fracture of the femoral neck within the capsule of the hip joint can cause a dislocated hip.
Step-by-step explanation:
A possible consequence following a fracture of the femoral neck within the capsule of the hip joint is a dislocated hip. The femoral neck is the part of the hip bone that connects the head of the femur to the shaft of the femur. When it fractures, it can cause the femoral head to become separated from the acetabulum, resulting in a dislocated hip.
