    摘要: An adjustable angle targeting device for an intramedullary nail includes a frame, a drill guide, and a holding member with both the drill guide and the holding member supported by the frame. The holding member includes a spherical upper surface, a lower surface, a first rotational alignment member for aligning the intramedullary nail with the holding member, and a bore extending through the holding member. The bore includes a circular lower portion opening to the lower surface and a slot shaped upper portion opening to the upper surface and having a length greater than the diameter of the circular lower portion. The targeting device further includes a holding bolt for insertion through the bore. The holding bolt includes a coupling portion for coupling with the intramedullary nail and axially aligning the intramedullary nail and a head with a bottom surface shaped complementary to the upper surface of the holding member.

    摘要: An apparatus for treating a bone fracture comprises an intramedullary rod extending through a first bone segment of a fractured bone. A lag screw assembly extends through a first transverse aperture in the rod, while a control member 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 mounted over a proximal portion of the lag screw. The locking sleeve defines a groove 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 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.

    摘要: A universal targeting apparatus includes a generally U-shaped body having one end configured to be coupled to the proximal end of the intramedullary implant and a mounting portion at an opposite end of said body. An arm is rotatably mounted to the mounting portion of the U-shaped body and includes bores defined at its opposite ends. Each bore is arranged at a different angle to correspond to the angle of a transverse aperture 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.

    摘要: 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.
