Central dislocation of Hip joint

The central dislocation of hip joint is a fracture-dislocation, shown in the image below, where the femoral head lies medial to a fractured acetabulum. This is caused by a lateral force against an adducted femur seen in side impact MVCs "motor vehicle collisions".

Fracture-dislocation of the right hip. The bony fragments are likely part of the acetabulum.
