20220265328 · 2022-08-25 ·

A bone fixation system includes a bone plate having an outer surface, an opposed bone-facing 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 compression surface. The system includes a bone fixation member having a shaft extending from a head along a central fixation member axis. The head has an exterior surface that defines a threaded head portion configured for variable angle locking with a complimentary variable angle plate locking structure. The compression surface and the threaded head portion are cooperatively configured to translate the bone plate in a direction substantially perpendicular to the central hole axis when the threaded head portion contacts the compression surface when the bone fixation member axis is offset from the central hole axis at an offset parameter as the head advances within the hole.

Bone plate and method of use
09814502 · 2017-11-14 ·

A bone plate assembly has the screws on one plate, either distal or proximal to the fracture, placed through round holes perpendicular to long axis of a first bone thus securing the plate rigidly to the bone on one side relative to the fracture. The screw holes can be either threaded on non-threaded. On the other side of the fracture, the bone fragment is first secured with an inclined screw placed from less than 90 to 10 degrees towards the fracture. As the screw is tightened it advances away from the fracture pulling the first bone, securely attached, plate towards the fracture site and thus compressing the fracture.

VARIABLE-ANGLE LOCKING SCREWS, AND BONE PLATE SYSTEMS THAT INCLUDE VARIABLE-ANGLE LOCKING SCREWS

A bone plate system may include a combination of one or more of a bone plate, non-locking screws, standard locking screws, and variable-angle locking screws. The bone plate may have threaded holes and non-threaded holes. Variable-angle locking screws may have a threaded shank and a threaded head. The threading on the head may be discontinuous, which allows the variable-angle locking screw to be inserted into a threaded hole on the plate at an angle relative to the axis of the threaded hole.

PROXIMAL HUMERAL STABILIZATION SYSTEM

Devices, systems, and methods for bone stabilization, especially proximal humeral stabilization. The stabilization system may include a bone plate having an elongated portion extending along a longitudinal axis and an enlarged head portion extending from the elongated portion. The stabilization system may include an intramedullary nail having an upper portion and a lower portion extending from the upper portion, the upper portion and the lower portion including a plurality of holes. A plurality of fasteners may be configured to extend through one or more of the plurality of through holes in the bone plate and/or one or more of the plurality of holes in the intramedullary nail and into the bone. The plate and nail may each be used alone or in combination together to stabilize a fracture in a long bone, such as a humerus.

Dynamic bone fixation element and method of using the same

The present invention relates to dynamic bone fixation elements and a surgical method to stabilize bone or bone fragments. The dynamic bone fixation elements preferably include a bone engaging component and a load carrier engaging component. The bone engaging component preferably includes a plurality of threads for engaging a patient's bone and a lumen. The load carrier engaging component preferably includes a head portion for engaging a load carrier (e.g., bone plate) and a shaft portion. The shaft portion preferably at least partially extends into the lumen. Preferably at least a portion of an outer surface of the shaft portion is spaced away from at least a portion of an inner surface of the lumen via a gap so that the head portion can move with respect to the bone engaging component. The distal end of the shaft portion is preferably coupled to the lumen.

Bone plate with a transfixation screw hole

A system for securing bones together across a joint includes a transfixation screw and a plate. The plate includes an elongate spine having a transfixation screw hole disposed along the spine. The transfixation screw hole includes an inner surface configured to direct the transfixation screw through the transfixation screw hole such that the transfixation screw extends alongside the bridge portion at a trajectory configured to pass through a first position on the first bone and a second position on the second bone once the plate is placed across the joint. The transfixation screw includes a head configured to abut the inner surface of the transfixation screw hole and a shaft configured to contiguously extend through the first bone, across the joint, and into the second bone.

Disposable orthopedic surgery kit and components

A disposable single indication orthopedic trauma surgical kit has no bone plates other than a single bone plate precountoured and sized to match an anatomic shape of a portion of a bone of a patient's extremity. The single bone plate has a plurality of fastener apertures. The surgical kit also has a plurality of fasteners with heads that are dimensioned to mate with the fastener apertures. The surgical kit also has a disposable torque driver adapted to engage the fastener heads. The foregoing components are contained in a sterile sealed container.

ORTHOPEDIC IMPLANT WITH IMPROVED VARIABLE ANGLE LOCKING MECHANISM

An orthopedic implant including an outer surface and at least one opening extending through the outer surface for receiving a fastener for coupling the implant to a patients bone or bone portion/fragment. The opening including a plurality of fins circumferentially disposed about the opening for engaging threads formed on a head portion of the fastener to secure the fastener to the implant. The plurality of fins being arranged and configured in first and second vertically spaced rows of fins. At least one of the fins including a different configuration, property, etc. relative to at least one of the other plurality of fins. In one embodiment, each of the first and second fins in a vertically stacked relationship includes a different configuration from the other of the first and second fins in that stack. In one embodiment, the different configuration includes a different length, a different thickness, or a combination thereof.

BALANCED AXIAL COMPRESSION ASSEMBLY FOR BONE
20220233221 · 2022-07-28 ·

Bone Plates Having Multi-Use Combination Holes For Locking And Dynamic Compression, And Related Systems And Methods

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.
