Patent number: 8591517Abstract: 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.Type: GrantFiled: October 3, 2012Date of Patent: November 26, 2013Assignee: Biomet C.V.Inventors: Anthony J. Metzinger, Charles D. Christie, Brad A. Parker, Andrew H. Berthusen

Patent number: 8182490Abstract: 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.Type: GrantFiled: June 20, 2008Date of Patent: May 22, 2012Assignee: DePuy Products, Inc.Inventor: Charles D.

Patent number: 8100911Abstract: 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.Type: GrantFiled: June 30, 2008Date of Patent: January 24, 2012Assignee: DePuy Products, Inc.Inventors: Ken Yamazaki, Andrew H. Berthusen, Anthony J. Metzinger, Charles D. Christie
