The authors have reviewed 25 cases of associated fractures of neck and shaft of the same femur. Some were treated conservatively, others were operated on. They conclude that the best treatment should be surgical on both foci. They recommend nailing of the shaft, the nail being introduced in the anterior aspect of the greater trochanter, and screwing of the neck, the screws being located behind the nail. In cases of low diaphyseal fractures plating was used. However a high rate of non-unions was noted in such cases.
