In some embodiments, a connector can be configured to couple a first fixation element (e.g., a first rod) to a second fixation element (e.g., a second rod). One or both of the first and second fixation elements can be included with the connector, or one or both can be separately provided. In some instances, at least one of the fixation elements is previously implanted in a patient. The connector can provide one or more degrees of freedom between the first and second fixation elements. The connector can also include a locking element configured to (1) lock one or more of the fixation elements to the connector, and (2) lock one or more of the degrees of freedom between the fixation elements. The connector can be configured to snap onto or otherwise engage a fixation element in a manner that provides tactile and/or audible feedback to the surgeon.

A spinal implant system includes a first bone fastener including a first head and a first shaft. The first head including a medial rod receiver offset from the first shaft. A second bone fastener is provided including a second head and a second shaft. The second head including a lateral rod receiver offset from the second shaft. The shafts are configured for fixation with vertebral tissue in alignment along a selected trajectory of the vertebral tissue. Surgical instruments, implants and methods are disclosed.

A bone fastener includes a head including a first receiver defining an implant cavity and a distal portion defining a plurality of adjacent grooves. The head further includes a second receiver defining an implant cavity. A first resilient member is configured for disposal within the plurality of adjacent grooves and a second resilient member is configured for disposal within the plurality of adjacent grooves. A shaft is aligned with the first receiver and is configured to engage tissue. Systems, surgical instruments, spinal constructs, implants and methods are disclosed.

A digital pedicle screw assembly may be installed inside of the body of a patient and be configured to sense various attributes of the assembly and the patient. Embodiments may include a receiver having a U-shaped cavity for supporting a longitudinal rod and set screw therein. The receiver may include a lower cavity configured to couple to a pedicle screw and a side portion integrally connected to the receiver and including a housing defining a sealed cavity for supporting a microelectronics assembly and a battery therein. Embodiments may include at least one antenna attached to an outside of the housing and being in electrical communication with the microelectronics assembly, and at least one strain gauge configured to detect a localized force experienced by the receiver and being in electrical communication with the microelectronics assembly.

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.

A polyaxial bone anchor has a locking element shaped and configured to allow an anchoring member (e.g., a screw or hook) to polyaxially rotate at large angles about a central axis of the bone anchor before compression locking the anchoring member within an anchor head.

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.

Connector assemblies, systems, and methods thereof. A modular connector has a first end that clamps to a first rod in an existing construct and a second end having a modular connection point configured to connect a second rod in a new construct such that the new construct can be extended from the existing construct.

A connector for connecting two supporting rods of a spinal column supporting device, which rods are placed or are to be placed along a portion of spinal column. The connector includes a transverse rod, a first coupling that couples the transverse rod to a first one of the supporting rods and a second coupling that couples the transverse rod to the second one of the supporting rods. At least one of the couplings has a clamping region that clamps the supporting rod with a clamping force and a force application component for generating an axial force that produces the clamping force, in particular in the form of an axial tensioning screw, the axial force being caused by screwing in of the screw, and the axial force being directed through the transverse rod.
