Abstract
An intramedullary intertrochanteric fracture fixation device includes an intramedullary nail having a proximal portion and a distal portion, a neck screw and a set screw assembly (). The intramedullary nail defines an angulated opening in the proximal portion and includes an axial bore extending through a proximal end of the nail and into the angulated opening. The proximal portion further includes a compartment defined by an upper stop, a lower stop and a sidewall. The sidewall of the compartment defines a slot. The neck screw is insertable the angulated opening and includes a length and an exterior surface defining a groove. The set screw assembly () is pre-operatively assembled within the proximal portion of the intramedullary nail and selectively moveable into the compartment for preventing rotational movement of the neck screw within the angulated opening of the intramedullary nail. The set screw is cannulated to receive a guidewire when pre-operatively assembled.
