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
