  • Patent number: 11471201
    Abstract: The cephalomedullary nailing system of this invention contributes to solving three main problems: reduce fractures, improve assembly biomechanics to ensure the load axis is favorable as possible for bony fragments and prevent femoral neck collapse as well as offset and limb length loss, hence avoiding the possibility of reduced abductor power. The system is based on specific screw channel geometry and the placement of an additional locking screw, allowing the nail to turn 360° and facilitating nail insertion through the screw.
