A bone plate for treating periprosthetic fractures includes a head portion to be positioned along a greater trochanter of a bone. The head portion includes pairs of bone fixation element receiving openings extending therethrough from a first surface of the plate which, when the plate is in an operative position, faces away from the bone, and a second surface which, when the plate is in the operative position, faces toward the bone. A pair of cable holes extend through the head portion from a first longitudinal side connecting the first and second surfaces to a second longitudinal side connecting the first and second surfaces. The head portion includes a pair of hooks for engaging a superior ridge of the greater trochanter. The plate also includes a shaft portion extending distally from the head portion to extend along a portion of the bone distal of the greater trochanter.

Implementations described herein include devices and systems for attenuation of increased spinal flexion loads post-fusion that include a transition member. The transition member may have a tension component coupleable to a fused vertebra of a plurality of fused vertebra of a fusion implant and to an adjacent unfused vertebra. The tension component may be tensionable to a selected value. The tension component may modulate a flexion range of motion of the adjacent unfused vertebra as a function of the selected value of tension of the tension component. The transition member may attenuate spinal flexion loads on adjacent unfused vertebra post-operatively.

The present invention provides a single surgical method, procedure and/or system that creates open visual and physical access to an identified spinal treatment site that initially comprises spinal levels to be treated, wherein the spinal levels comprise at least one dorsal root ganglion. A spinal treatment procedure is performed generally in combination with implantation of a neuromodulation system that may comprise placement of electrical lead(s) on the at least one dorsal root ganglion, wherein each lead is in operative connection with a pulse generator that may also be implanted during the surgical method. Electrical stimulation may be generated with the pulse generator through the electrical leads to the at least one dorsal root ganglion during and/or after the closure of the identified spinal treatment site.

Connector assemblies, systems, and methods thereof. A connector has a first end that clamps to a first rod in an existing construct and a second end, connected to the first end, that clamps to a second rod in a new construct such that the new construct can be extended from the existing construct at an adjacent level as the existing construct.

A dynamic longitudinal connecting member assembly includes an anchor member having an integral or otherwise fixed elongate core of circular or non-circular cross-section. The core is pre-tensioned and extends through at least one elastic spacer and at least one outer sleeve. The anchor member and the outer sleeve each attach to at least one bone anchor. In operation, the core is held in tension by the spacer.

A surgical kit includes a shield for covering a portion of the spine of a subject. The shield can include an attachment portion adapted to engage a bone fixation assembly which is adapted to be fixed on multiple vertebra bones of the subject. The bone fixation assembly can include a vertebra joining member secured between two bone anchors. Each bone anchor can include a fastener portion adapted to be implanted into a vertebra bone and a head coupling portion adapted to secure the vertebra joining member. The shield can be coupled to the bone fixation assembly via separate coupling elements, such as a clip or an adjustable link secured between two vertebra joining members of the bone fixation assembly. Alternatively, the shield can include an integral attachment portion configured to engage the bone fixation assembly directly.

Implants with grip grooves are disclosed herein. In some embodiments, an implant includes a rod-receiving recess defining a rod axis where an inner surface of the rod-receiving recess defines two grip grooves extending parallel to each other and the rod axis. Each grip groove defines two edges where the grip groove intersects the inner surface, the four edges of the two grip grooves together defining a circular radius about the rod axis. The implant includes a retaining member configured to move with respect to the body to apply a force against a rod that is perpendicular to the rod axis, the force engaging the rod against the four edges of the grip grooves, where the engagement of the four edges of the grip grooves against the rod restrains rotational movement of the rod about the rod axis.

A spinal fixation device for securing two stabilizing rods to bone has a threaded shaft, a first rod coupling head connected to the threaded shaft and a secondary rod coupling head. The first rod coupling head has a side wall and a cavity with an open top for receiving a rod. In a neutral position of the first rod coupling head, the first rod coupling head extends symmetrically around the longitudinal axis of the threaded shaft. The second rod coupling head is rotatably connected to the first rod coupling head, around an axis of rotation. The axis of rotation is disposed at an angle that is not perpendicular to the longitudinal axis of the threaded shaft when the first rod coupling head is in the neutral position. This allows for two rods to be manipulated independently through different axis planes at any single point of bony fixation.

The present invention provides a single surgical method, procedure and/or system that creates open direct visual and/or physical access to an identified spinal treatment site that comprises both targeted vertebral and spinal levels to be treated, wherein the spinal levels comprise at least one dorsal root ganglion. A spinal treatment procedure may be performed generally in combination with implantation of a neuromodulation system that may comprise placement of electrical lead(s) on the at least one dorsal root ganglion, wherein each lead is in operative connection with a pulse generator that may also be implanted during the surgical method. Electrical stimulation may be generated with the pulse generator through the electrical leads to the at least one dorsal root ganglion during and/or after the closure of the identified spinal treatment site.

Implants, systems, and methods for securing a flexible band, thereby providing a desired correction to the spine. The implant may secure the flexible band to a spinal rod and/or a pedicle screw. The implant may include a first locking member configured to secure the spinal rod and a second locking member configured to secure the band. The band may be looped around bony anatomy and tensioned to achieve correction and provide fixation as an alternative and/or supplement to pedicle screws during spinal deformity surgery.
