Bone Plates Having Polygonal Locking Holes With Thread Interruption, And Related Systems And Methods
Publication number: 20250009399Abstract: A bone plate defines an interior surface that defines: a hole extending through the plate along an axis; plate threads configured for locking with a threaded head of a locking screw; first, second, and third columns sequentially located about the axis; a first corner extending tangentially from the second to the first column; and a second corner extending tangentially from the third to the first column. The first and second corners are substantially equidistantly spaced from the axis. The plate threads extend across the first, second, and third columns and the first and second corners. The interior surface defines a recess between the second and third columns and facing the first column. An apex of the recess is spaced further from the axis than are the first and second corners, such that the recess circumferentially interrupts at least a portion of at least one of the plate threads.Type: ApplicationFiled: September 13, 2024Publication date: January 9, 2025Inventors: Steffan Daniel, Andreas Baeriswyl, Sol Posada, Joel Oberli, Mirko Rocci -
Patent number: 12178481Abstract: A bone plate includes a plate body defining an interior surface that defines a combination hole that includes intersecting locking and compression holes that each extend between outer and bone-facing surfaces of the plate body. A central axis of the compression hole is spaced from a central axis of the locking hole in an offset direction. A locking surface of the plate body defines the locking hole and at least one locking structure therein. A compression surface of the plate body defines the compression hole. An intersection boundary between the locking and compression surfaces is configured to translate the bone plate in the offset direction during contact between the intersection boundary and a head of a compression screw as it advances within the combination hole along an insertion axis offset from the central axis of the locking hole at an offset distance in a direction having a directional component in the offset direction.Type: GrantFiled: January 22, 2021Date of Patent: December 31, 2024Assignee: DePuy Synthes Products, Inc.Inventors: Steffan Daniel, This Aebi, Andreas Baeriswyl, Joel Oberli, Mirko Rocci

Patent number: 8764752Abstract: A system for inserting an intramedullary nail into a bone includes (a) a handle extending from a proximal end to a distal end configured to couple to an intramedullary nail only in a desired orientation and (b) an aiming device extending from a proximal end to a distal end configured for attachment to the proximal end of the handle. The aiming device includes a guide opening extending therethrough sized and shaped to accommodate a protective sleeve therein. The guide opening is located and oriented so that, when the aiming device and the handle are coupled to one another, a bone fixation receiving hole in an intramedullary nail coupled to the handle is aligned with the guide opening. The aiming device further includes a locking pin fixedly mounted thereto. The locking pin extends into the guide opening to engage a protective sleeve inserted therein.Type: GrantFiled: July 21, 2011Date of Patent: July 1, 2014Assignee: Depuy Synthes Products, LLCInventors: Markus Buettler, Simone Volzer, Andreas Baeriswyl

Patent number: 8449576Abstract: The present invention is directed to a dynamic fixation system for engaging, via bone fixation elements, one or more parts of a patient's body. Preferably, the dynamic fixation system is used to engage one or more vertebrae for stabilizing the attached vertebrae with respect to one another while still permitting the vertebrae to move with respect to one another. The dynamic fixation system may include a first rod having first and second ends, a second rod having first and second ends, and a damping component and/or a damping mechanism for interconnecting the first and second rods. In one embodiment, the damping component is injection molded in-between the one of the ends of the first rod and one of the ends of the second rod so that the first and second rods are prevented from separating with respect to one another but are still permitted to move with respect to one another.Type: GrantFiled: June 28, 2007Date of Patent: May 28, 2013Assignee: DePuy Synthes Products, LLCInventors: Beat Lechmann, Volker Engelmann, Markus Kraft, Michael Gabl, Andreas Baeriswyl
