Patent number: 8241286Abstract: An instrument system is provided for positioning an internal fixation prosthesis and guiding a cannulated bone drill during a surgical, radioscopic procedure for the repair of a fractured bone of a patient. The instrument system includes a target wire, a handle formed from a radio translucent material having a target hole for guided passage of the target wire along a target axis. The target axis coincides with the intersection of a first plane and a second plane orthogonal to the first plane. The instrument system also includes a nose component attached to an end of the handle and removably connectable to the prosthesis. The nose component includes an alignment sight formed from a radio-opaque material.Type: GrantFiled: August 26, 2009Date of Patent: August 14, 2012Assignee: Biomet, C.V.Inventors: Anthony J.

Publication number: 20080147124Abstract: A bone plate system includes a bone plate with movable portions and locking screw assemblies. The locking screw assemblies may be locked to the movable portions of the bone plate and then dynamized to either distract or compress bone fragments.
