CONTOURED BONE PLATE WITH LOCKING SCREW FOR BONE COMPRESSION, PARTICULARLY ACROSS A TARSOMETATARSAL JOINT
A method of applying a bone plate across a tarsometatarsal joint or two different portions of a metatarsal may involve positioning a bone plate across a separation between two bone portions. The bone plate can have at least two fixation holes and a bend between the holes. A locking screw can be inserted through one or both holes that has a head thread and a shaft thread, where the shaft thread has a pitch greater than a pitch of the head thread. The locking screw can be screwed into an underlying bone portion until the bend in the bone plate is deformed.
CERCLAGE CABLE SYSTEM AND APPARATUS
A cerclage cable system is disclosed which includes a bone plate, one or more securing devices, and one or more cerclage cables. The bone plate includes a plurality of bone plate apertures thereupon, wherein the bone plate is configured to be affixed to a bone. The one or more securing devices include a body having a proximal end and a distal end, wherein at least one securing device aperture is disposed toward the proximal end, wherein the distal end of the securing device is configured to be inserted into and received by the plurality of bone plate apertures. The one or more cerclage cables include two terminal ends, wherein the one or more cerclage cables are wrapped around the bone, wherein one terminal end of the one or more cerclage cables is passed through at least one securing device aperture.
Clavicle segmental plate system
A medial plate for treating fractures along a clavicle, comprising a plate body including a longitudinal component extending from a first end to a second end and an extension extending from the second end, the second end configured to be mounted over a medial head, a first set of variable angle holes extending through a portion of the longitudinal component including the second end of the longitudinal component and the extension, each of the first set of variable angle holes extending through the plate body along a central axis so that a bone screw is insertable therethrough at a user-selected angle relative to the central axis, and a plurality of combination holes extending through the longitudinal component, each of the plurality of combination holes includes a first portion configured to receive a bone screw at a user-selected angle and a second portion configured to receive a compression screw.
BONE PLATE WITH MOVABLE JOINT
System, including methods and devices, for fixing bone. The system may include a bone plate having two or more plate members connected to one another with one or more movable joints. Each joint may permit the orientation of the plate members to be adjusted relative to one another in a single plane or two or more nonparallel planes. The joint may have a movable configuration and a fixed configuration. Methods of creating the bone plate are also provided.
WRIST STABILIZATION SYSTEMS
Devices, systems, and methods for bone stabilization, especially ulna head stabilization. The stabilization system may include a bone plate having an elongated portion extending along a longitudinal axis between a proximal end and a distal end. The bone plate defines a plurality of through holes extending through the elongated portion. A plurality of fasteners are configured to extend through one or more of the plurality of through holes in the bone plate and configured to secure the bone plate to the bone. The proximal end of the elongate portion has an arcuate configuration.
ORTHOPEDIC IMPLANT SYSTEM FOR VARIABLE ANGLE LOCKING HAVING ENGINEERED MATING THREAD ENGAGEMENT
The invention relates to an orthopedic implant system comprising an implant including a threaded aperture which receives either a first non-locking bone fastener or a second threaded variable axis locking fastener. The threaded aperture includes interruptions to form sections having a thread segment. The variable axis locking fastener has a threaded head configured to cause the threads to wedge against the female threads of the aperture as the fastener is tightened into the aperture in an off-axis orientation. In a further embodiment, the aperture includes a concentric annular groove to form flexible threaded fines.
Surgical bone screw and implant system
The invention relates to a surgical bone screw comprising a shaft which has a bone thread and comprising a blocking means for interacting with a bone plate or for directly anchoring in the bone, in particular in the cortical bone. The surgical bone screw also comprises a screw head which has a rotationally symmetrical enveloping contour. The blocking means has a rib structure with at least one flank structure portion extending in the circumferential direction. According to the invention, the lateral surface of the enveloping contour has a constant or stepped concave progression, and the rib structure flank portion which extends in the circumferential direction is interrupted at least once in the circumferential direction, in particular multiple times, such that at least one elevation, in particular a plurality of elevations which are spaced in the circumferential direction, is produced in order to interact with the bone plate or with the bone in a blocking manner.
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.
Stabilization systems
Devices, systems, and methods of bone stabilization. The bone stabilization system includes a mesh body. The mesh body includes a plurality of rings, with each of the rings defining a screw hole. Bridge portions extend between and interconnect the rings. The bridge portions have a reduced thickness compared to the rings. An elongate body may also extend from the mesh body. The elongate body defines at least one screw hole.
Bone fixation system including an implant having a plate portion and a mesh portion
A bone fixation system is configured to be implanted and secured to a bone so as to stabilize a bone. The bone fixation system includes an implant having a plate portion configured to be secured to a first segment of the bone by a first bone anchor, and a second segment of the bone by a second one anchor. The implant further includes a mesh portion configured to abut a third segment of the bone to prevent movement of the third segment relative to both the first segment and the second segment. The implant defining an outer perimeter defined in part by the plate portion and in part by the mesh portion.
