Patent number: 9339310Abstract: Devices and methods for facilitating insertion of a spinal rod into a rod-receiving channel formed in a bone fixation element are described herein. In some embodiments, a reduction sleeve can include a through-bore sized to receive the bone fixation element and a transverse channel sized to receive the spinal rod and substantially aligned with the rod-receiving channel formed in the bone fixation element. The reduction sleeve can also include at least one break-off point for breaking and removal of the reduction sleeve The reduction sleeve can also include a plurality of threads for engaging a reduction instrument, an alignment mechanism so that the bone fixation element can only be inserted into the reduction sleeve when the rod-receiving channels are aligned, and an inwardly projecting protrusion formed on the inner surface of the reduction sleeve so that, once inserted, the projection contacts a top surface formed on the bone fixation element.Type: GrantFiled: January 23, 2014Date of Patent: May 17, 2016Assignee: DePuy Synthes Products, Inc.Inventors: Brian Dec, David S.

Patent number: 8940020Abstract: A connector for engaging two or more rods is disclosed. The connector includes a main body, at least two medial bodies and a compression mechanism. Generally, the connector provides for easy “snap-fit” lateral insertion of the rods into rod openings defined between the medial bodies and the main body. The snap-fit is achieved through a spring bias exerted by the compression mechanism. The compression mechanism may also be configured to lock the rods within the openings, such as through the use of a fastener.Type: GrantFiled: April 6, 2012Date of Patent: January 27, 2015Assignee: DePuy Synthes Products, LLCInventor: David S.

Publication number: 20120283782Abstract: Translational bone fixation assemblies, kits containing such assemblies, and methods of use are described herein. The described assemblies may be used in spinal fusion procedures in which a damaged or diseased disc (or part of a disc) is removed from between a pair of vertebrae and a spinal fusion spacer is placed between the vertebrae. The assemblies may be applied to an anterior portion of the affected vertebrae to span the affected disc space, and may be fixed to the vertebrae using bone screws. The assemblies may function to maintain the vertebrae aligned during the initial period following fixation in which fusion of the spacer to the adjacent vertebrae occurs. The assemblies may also function to share some of the axial spinal load applied to the fusion spacer to prevent extreme subsidence of the spacer into the vertebral body, such as where the patient has poor bone quality.Type: ApplicationFiled: July 13, 2012Publication date: November 8, 2012Inventors: Christopher J.
