[Osteosynthesis of the subtrochanteral fractures of the femur by using Küntscher's pin].

The method of intramedullary introduction of the Küntscher pin in order to penetrate, immobilize and stabilize a subtrochanteral fracture of the femur in children and adults has given excellent anatomical and functional results. This method is effective because it synthesizes the positive elements of a mechanical, vascular and biomechanical nature. The results published in our own and foreign literature and our own results indicate that this method is effective; it is a simple, quick technique which saves the tissue of the affected area from injury and maintains optimal functioning of the extremity.
