Abstract: Plates for patella fracture reduction and fracture reduction devices are described. More particularly plates and devices for patella reduction that are universally fit to a front surface or perimeter of a patella and include a plurality of attachment holes disposed therein for receiving a fastener. In some embodiments, the plates include removable tab members.

Abstract: An intramedullary device, having a first longitudinal axis extending between a proximal end and a distal end thereof, is provided. The intramedullary device may include a first bore and a second bore. The first bore may include a second longitudinal axis and may extend through the intramedullary device between a first opening and a second opening. The second longitudinal axis may define a first angle (?1) with the first longitudinal axis. The second bore may include a third longitudinal axis and may extend through the intramedullary device between the first opening and a third opening. The third longitudinal axis may define a second angle (?2) with the first longitudinal axis.

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.

Abstract: 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.

Abstract: A hip screw assembly for fixation of a fractured femur is provided. The hip screw assembly includes a screw for engagement with the femur. The hip screw assembly also includes a barrel defining a cavity in the barrel. The barrel is fixedly secured to the plate. The screw including a portion thereof fitted in the cavity of the barrel. The hip screw assembly also includes a stop positionable in the barrel. The stop provides a limit on the movement of said screw in said barrel. The screw and the barrel have a first arrangement between each other in which the screw slides in the cavity of said barrel a first selectable predetermined distance and a second arrangement in which the screw slides a second selectable predetermined distance. The second distance is greater than the first distance.
