An implantable fixation device for rejoining opposed portions of a separated bone. The device including two corresponding plates that are configured to be aligned and coupled to a bone, such as a sternum, pre-resection of the bone or prior to cutting/separating the bone. The placement of the corresponding plates provides a gap between the edges of the plates that face one another allowing for and guiding a cutting tool for separating the bone. After the bone has been cut and the desired surgical procedure performed, the plates also assist in realigning and fixation of the bone portions. At least one plate includes a ratchet mechanism that is configured to tighten a locking element and draw the two plates together and into alignment with one another.

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.

Bone surgical plate devices and methods for use in bone fracture surgeries, for example, clavicle fracture surgery. The systems and methods can include a plate device with specific design features including but not limited to differing designs, geometries, and configurations in multiple segments of the device.

A compression force magnifier comprising: an engaging surface for attaching to a bone plate; a ramped component above the engaging surface, the ramped component having a bottom surface adjacent the engaging surface and an angled upper surface; and a hole extending through the ramped component and the engaging surface.

Bone plates are disclosed for veterinary uses. For example, the bone plates could be utilized for repairing distal humerus fractures in canines or felines. The bone plates may include various features for better accommodating the anatomy and native tissue structure of the distal humerus of an animal and may be utilized for all distal humerus fracture patterns.

A cervical plate assembly is disclosed. The cervical plate assembly includes a base plate including: (1) at least two bone screw seats, each bone screw seat including a borehole dimensioned to receive a bone screw, and (2) a first blocking seat positioned between the at least two bone screw seats. The cervical plate assembly includes a blocking mechanism retained within the first blocking seat of the base plate. The blocking mechanism is selectively positionable between a closed position in which the blocking mechanism obstructs at least one bone screw seat to retain a bone screw with the base plate, and an open position in which the bone screw seats are unobstructed.

A spine plate implant utilizes cam lock setscrews to retain bone screws in the plate once implanted. A cam lock setscrew is received in a setscrew pocket adjacent a configured bone screw bore of the plate and is configured to allow a bone screw to be received in the plate when in an unlocked rotational position, and to retain the received bone screw when in a locked rotational position. The bone screw may include a tang that allows engagement with external teeth of the cam lock setscrew when the cam lock setscrew is rotated into the locked position. Once the cam lock setscrew is in the locked position, the bone screw is inhibited from backing out of the bone screw bore. When the cam lock setscrew is in the unlocked position, a flat of the cam lock setscrew is adjacent the bone screw tang so the bone screw may be removed.

Systems for treating bone fractures are disclosed. Exemplary systems may include a backpack and one or more bone plates for engaging bone members. The backpack may be configured to be temporarily attached to the bone plate in order to provide trajectories for fasteners received by the bone plate. The bone plates can receive one or more screws to secure the bone plates to an underlying bone member. The one or more screws can be inserted into bone plate holes that can be considered locking or non-locking. The bone plates described herein can have particular combinations of locking and/or non-locking holes. Additional bone plate holes can be used to accept sutures, K-wire, or other instrumentation.

A bone fixation assembly is disclosed. The bone fixation assembly may include a bone fixation plate including a fastener hole and a cavity adjacent to the fastener hole. The bone fixation assembly may also include a clip. The clip may include a body having a partial circular shape, the body positioned at least partially in the cavity. The clip may further include a plurality of tabs extending inward relative to the partial circular shape of the body, each tab having a convex shape extending inward relative to the partial circular shape of the body, wherein the body and the plurality of tabs are positioned below a top surface of the bone fixation plate.
