    Abstract: An apparatus for treating a bone fracture comprises an intramedullary rod (12) extending through a first bone segment of a fractured bone. A lag screw assembly (14) extends through a first transverse aperture in the rod, while a control member (16) extends through a second transverse aperture longitudinally offset from the first aperture. The lag screw assembly includes a lag screw engaged to the second bone segment and a locking sleeve (40) mounted over a proximal portion of the lag screw. The locking sleeve defines a groove (44) aligned with the second aperture. The control member includes a distal portion penetrating the bone segments, an intermediate portion configured to engage the second aperture, and an enlarged head (65) configured to slidably engage the groove. The groove includes a terminus that contacts the head of the control member after a predetermined amount of lateral migration of the lag screw as the fracture collapses.

    Abstract: A universal targeting apparatus (30,100) includes a generally U-shaped body (32, 102) having one end (36,104) configured to be coupled to the proximal end (18) of the intramedullary implant (10) and a mounting portion (46,112) at an opposite end of said body. An arm (34,125) is rotatably mounted to the mounting portion of the U-shaped body and includes bores (67,73,131,136) defined at its opposite ends. Each bore is arranged at a different angle to correspond to the angle (A) of a transverse aperture (14,15) in the intramedullary implant. The arm can be rotated so an appropriate one of the angled bores is aligned with the transverse aperture to serve as a guide for creating targeting holes in the bone.

    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.
