Unusual traumatic anterior dislocation of the hip

Four interesting cases of traumatic anterior dislocation of the hip are presented. All were easily reduced by closed manipulation, including one complicated by a subtrochanteric fracture of the same femur. Early reduction and mobilization have resulted in good early results, though the risk of late change in the shape of the femoral head still exists in one of the cases. Another case confirmed that an abduction force on the flexed hip can produce anterior dislocation of the hip.
