A receiver assembly for securing an elongate rod to a bone anchor includes a receiver having a channel configured to receive the elongate rod and a helically wound receiver guide and advancement structure formed into interior surfaces of the receiver. The receiver assembly further includes a threaded plug configured for positioning within the channel to secure the elongate rod to the receiver in a locked configuration, with the threaded plug having a lower axially protruding portion configured to compress the rod so as to prevent rotational and axial movement between the rod and the receiver in the locked configuration.

Open implant closure structures include a helically wound guide and advancement flange form having splay control surfaces. Multi-start closures and closures with inner set screws have splay control contours for interlocking with cooperating flange forms of bone anchor receivers. Flange form heights, thicknesses and other geometry, such as splay control ramp angle may be varied.

To provide a corrective appliance capable of properly assisting in correction of spinal deformity by a spinal deformity correction and fusion system while limiting damage on a rod member when the spinal deformity is subjected to correction and fusion by the spinal deformity correction and fusion system. A corrective appliance includes: a clamp member to be attached detachably to a screw member, for example, and to be arranged close to the screw member; and an auxiliary rod member to be attached detachably to the clamp member and to be used for correcting spinal deformity. This allows the corrective appliance to properly assist in correction of spinal deformity by a spinal deformity correction and fusion system while limiting damage on a rod member when the spinal deformity is subjected to correction and fusion by the spinal deformity correction and fusion system.

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 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 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. One or more modular connectors has a first portion that clamps to a first rod in an existing construct and a second portion that clamps to a second rod in a new construct such that the new construct can be extended from the existing construct.

A system and method for an electrically enhanced surgical implant comprising: an implant body that includes an inner frame, wherein the inner frame includes a set electrode sites, and an over-coating that is formed over the inner frame, leaving the electrode sites exposed on the surface of the implant body; a circuitry casing, electrically and mechanically connected to the implant body, implant circuitry, situated at least partially within the implant casing, comprising receiver circuitry, effective to convert an electromagnetic field to electric current, control circuitry, and a power source; a set of conductive paths, wherein each conductive path has a first portion, electrode, situated on an electrode site, and a second portion, electrical conduit, that extends on and through the inner frame and electrically connects the electrode to the implant circuitry in the circuitry casing. The system functions as an electrically enabled surgical implant, such that the surgical implant can provide precisely determined and localized electrical stimulus as part of the implant operation.

A method and apparatus is disclosed for the surgical installation of a nail for stabilizing a screw-rod configuration attached to vertebrae of a spine to the rib cage of an organic body to treat Adult Spinal Deformity (ASD) and prevent proximal junctional failure (PJF). The nail may be secured at one end to an adjacent rib of the rib cage, and may extend into the rib or be secured to the rib by a rib hook. The nail may be secured at another end to a rod of the screw-rod configuration, such that the nail imparts stability from the rib cage to the screw-rod configuration and to the vertebrae of the spine.

A device, kit and method for the correction of spinal deformity using an anterior approach. The device comprises a screw-head platform (102), wherein the screw-head platform (102) comprises a primary recess (112) for receiving a primary rod (114), and a main vertebral body screw (104) rotatably connected to the screw-head platform (102).

An implantable body for a posterior stabilization system includes a lateral end, a medial end, an inwardly facing surface configured to abut against a lamina when the body is implanted along a vertebra. A lateral bone outrigger extends from the inwardly facing surface and may include a bone-abutting surface along a medial portion disposed to abut against a lateral mass of the vertebra when the body is implanted along a vertebra. The lateral bone outrigger may have a first height. A penetrating feature extends from the inwardly facing surface between the bone-engaging portion of the inwardly facing surface and the lateral bone outrigger. The penetrating feature may have a second height less than the first height. A fastener bore extends through the body at an angle toward the lateral bone outrigger.

A method for robotic assisted surgery. The method includes capturing a plurality of poses of a surgical tool coupled to a robotic device at a surgical site. The plurality of poses correspond to instances of a final placement of surgical implants at the surgical site. The method also includes determining a plurality of positions of the surgical implants located at the surgical site based on the captured plurality of poses. The method also includes generating a bend curve having a plurality of bend points based on the determined plurality of positions of the surgical implants. The method also includes generating bending instructions for bends to be performed on a linking device configured for attachment to the surgical implants.
