A system and method for a multi-axial connection of an apparatus to bone. The system may include a fastener inserted into a body and a head of the fastener held within a chamber of the body through a combination of a retention ring, a pressure cap, a rod, and a compression element. The compression element applies force to the rod which, in turn, pushed on the pressure cap. The force on the pressure cap urges it against the head of the fastener and pushed it against the retention ring. The force on the retention ring causes it to expand to the walls of the chamber. Once the ring can no longer expand within the chamber, the head of the fastener is wedged between the retention ring and the pressure cap.

Multi-axial connection system

The present disclosure relates, according to some embodiments, to orthopedic implantable device technology, and more specifically to implantable devices for use in stabilizing the occipitocervical junction and the cervical spine. For example, the disclosure relates to embodiments of an implantable orthopedic assembly generally comprising an occipital plate and one or more repositionable clamping assemblies for securing a stabilizing rod at a nonzero distance from a plate surface. One or more rails may extend laterally from a plate to support a clamping assemblies.

Rod attachment assembly for occipital plate

The present disclosure relates, in some embodiments, to locking mechanisms for a fastener (e.g., a bone screw) and associated devices, systems, and methods. According to some embodiments, a lockable bone plate assembly may comprise, for example, a bone plate and a bone screw assembly. A bone plate may comprise, in some embodiments, at least one through hole, the at least one through hole having at least one bone plate hole circumferential recess. According to some embodiments, a bone screw assembly may comprise (a) a bone screw, (b) at least one deployable protrusion, and/or (c) a protrusion driver. The present disclosure further relates, in some embodiments, to methods for bone (e.g., vertebral) fixation. For example, a method may comprise contacting at least a portion of a spine (e.g., cervical spine) of a subject with a lockable bone plate assembly.

Plate/screw locking mechanism devices, systems and methods

An implantable orthopedic assembly comprises a bone fixator and head assembly for securing a stabilizing rod to the spine. The head assembly allows multi-axial repositioning of the bone fixator relative to the head assembly. A primary drive interface located on the bone fixator may be used to adjust the depth of bone penetration when the bone fixator and head assembly are substantially coaxial. A secondary drive interface located on the head assembly may be used to adjust the depth of bone penetration while independently adjusting the stabilizing rod position when the bone fixator and the head assembly are not coaxial, transferring torsional loads to the bone fixator.

Multi-axial pedicle fixation assembly and method for use

A cross connecting device suitable for connecting first and second spinal fixation devices comprises a fixable pivot junction, first and second connection members, and first and second clamps. The fixable pivot junction includes a pivotable joint that is pivotable about a pivot point. The fixable pivot junction also includes a collar configured for fixating the pivot junction. The first and second connection members are connected by the fixable pivot junction such that the fixable pivot junction allows the first and second connection members to be repositioned relative to each other. The first and second clamps are connected to respective ones of the first and second connection members at distal ends of the connection members relative to the fixable pivot junction. The first and second clamps allow the cross connecting device to be clamped on to spinal fixation devices, such as pedicle screws or hooks.

Multi-axial spinal cross connecting device

An implantable orthopedic assembly comprises an occipital plate and one or more repositionable clamping assemblies for securing a stabilizing rod to the plate. When unlocked, the clamping assembly may be laterally and rotationally repositioned along a supporting rail. Locking occurs when a stabilizing rod is secured in the clamping assembly. The rod exerts a force upon a locking component, causing the locking component to exert a force upon the supporting rail. This force pulls a surface of the clamping assembly base into contact with the rail, effectively locking the clamping assembly base at a fixed position. The clamping assembly may further comprise a loading component to exert a stabilizing force on the locking component, keeping the clamping assembly positionally stable while adjustments are made prior to locking.
