  • Patent number: 9782205
    Abstract: A tibiotalar fusion system includes that includes a curved fusion nail and interlocking fasteners, along with delivery instrumentation. The curved ankle fusion nail is delivered with the fasteners in such a manner that the curved ankle fusion nail does not pass through the subtalar (talocalcaneal) joint. The curved fusion nail thus preserves the subtalar (talocalcaneal) joint and the natural motion of the hindfoot within a mammal such as, for example, a human. Additionally, drill guided delivery instrumentation and surgical methods of delivering and fixing the curved tibiotalar nail within a desired anatomical location such as the ankle.
