    摘要: 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.

    摘要: A device for correcting a placement of a guide wire in a bone includes a body extending from a proximal end to a distal end; a central channel extending through the body from the proximal end to the distal end along a central axis, the central channel sized and shaped to receive a guide wire slidably therein; and a first correction channel extending through the body from the proximal end to the distal end. The first correction channel is sized and shaped to receive a guide wire therein at an angle relative to the central axis of the central axis of the central channel.

    摘要: A bone plate includes a plate body defining an outer surface, an opposed bone-facing surface, and a combination hole comprising a locking hole and a compression hole that intersect one another and each extending from the outer surface to the bone-facing surface. The locking hole and the compression hole extend away from each other along a longitudinal axis. The plate body further defines a locking surface that defines the locking hole, and a second surface that defines the compression hole. The locking surface further defines a plurality of columns sequentially located about a central axis of the locking hole, a plurality of recesses located, respectively, between at least some of the columns, and plate threads that traverse each of the columns. Crests of the plate threads extend linearly from a first side of each column to a second side of each column.

    摘要: 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.

    摘要: A variable angle bone screw includes a first portion and a second portion that is separate from the first portion and configured to be attached to the first portion. The first portion defines at least a portion up to an entirety of the threaded head of the variable angle bone screw. The second portion defines at least a portion up to an entirety of the threaded shaft of the variable angle bone screw. The threaded head can have a first material hardness, and the threaded shaft can have a second material hardness that is less than the first material hardness.

    摘要: A drill sleeve, including: an outer sleeve with an internal collet at a distal end of the outer sleeve, a slot, and an inner opening; a handle connected to the outer sleeve; an inner sleeve with an inner opening configured to receive and guide a drill bit, wherein the inner sleeve is configured to slide inside the inner opening of the outer sleeve; a trigger; a connection member connected to trigger and the inner tube, wherein the connection member passes through the slot in the outer sleeve and a biasing member configured to apply a biasing force between the handle and the trigger wherein the biasing force drives the inner sleeve into the outer sleeve, wherein when a distal end of the inner sleeve engages the internal collet, the internal collet is configured to engage a screw hole in a bone plate, align the drill sleeve with a nominal axis of the screw hole, and secure the drill sleeve to the screw hole.

    摘要: A bone plate has an outer surface, a bone-facing surface opposite the outer surface, and an interior surface that defines a hole extending from the outer surface to the bone-facing surface along a central hole axis. The interior surface further defines a ramp that extends from the outer surface toward the bone-facing surface and plate threads that extend from the ramp toward the bone-facing surface and are configured for optional locking engagement with external threads on a first head of a locking bone fixation member. The interior surface further defines a contact profile in a reference plane that extends along the central hole axis. The contact profile is defined at least by the ramp and is spaced from the central hole axis in an offset direction perpendicular to the central hole axis. The contact profile is configured to translate the bone plate in the offset direction responsive to contact with an exterior surface of a second head of a compression bone fixation member as the second head advances within the hole along an insertion axis that is offset from the central hole axis in the offset direction.
