Lower limb abduction

The acetabulum and the femoral head, which form the hip joint, are closely matched in form. It is a typical club and mortar joint with strong ligaments and strong muscle groups around it. Therefore, only strong violence can cause hip dislocation. In car accidents, violence is often high-speed and high-energy, and multiple traumas are not uncommon for this. According to the direction of the femoral head dislocation, it can be divided into anterior, posterior and central dislocations. Later dislocations are the most common.
