Injury mechanism of femoral neck fracture combined with obturator dislocation. The inner side of the proximal femur hits the outer and upper parts of the femoral head. After the second impact, the femoral head dislocated to the obturator through the sartorius tunnel and was blocked by the pubic branch, resulting in a fracture of the inferior pubic branch, which eventually caused the femoral head to be embedded in the obturator
