Abstract:
1. An intramedullary nail assembly, comprising: an intramedullary rod having a proximal end, a distal end, a wall defining an elongated hollow enclosure, a first through opening in the wall spaced from the proximal and distal ends and closer to the proximal end than the distal end, and a second opposing through opening in the wall spaced from the proximal and distal ends and further from the proximal end than the first through opening; a spherical ball joint in the hollow enclosure of the intramedullary rod having a through bore that opens to the first and second through openings in the wall; and a securing mechanism in the hollow enclosure that engages the spherical ball joint and is configured to lock the ball joint at a predetermined orientation relative to the first and second through openings in the wall, the securing mechanism having a cam lock including a rotating member and a pressure member, the rotating member being rotatable to push the pressure member into engagement with the spherical ball joint to lock the ball joint at the predetermined orientation.
