Abstract:
An intramedullary nail comprises longitudinal channel, a first transverse passage and a second transverse passage. A lag screw extends through the first transverse passage of the intramedullary nail. An anti-rotation shaft extends through the second transverse passage of the intramedullary nail. A cannulated lag screw lock is positioned in the intramedullary shaft and engages the lag screw. The anti-rotation shaft extends through a cross channel in the lag screw lock. A second shaft lock is positioned in the intramedullary nail with the second shaft lock engaging the anti-rotation shaft. In at least one embodiment, the lag screw lock includes a substantially cylindrical body portion rotatably connected to a threaded head portion. In at least one embodiment, the second shaft lock is provided as an end cap including a threaded upper portion and a lower post portion that extends into the lag screw lock.
