Bone anchor assemblies and related methods are disclosed herein that can provide for improved fixation of a primary bone anchor. A bone anchor assembly can include a wing with a distal portion that can define a plurality of auxiliary bone anchor openings. Each auxiliary bone anchor opening can receive an auxiliary bone anchor that can augment fixation of a primary bone anchor of the bone anchor assembly. The plurality of auxiliary bone anchor openings can be oriented such that, when the wing is coupled to a primary bone anchor assembly of a vertebral level in a first configuration, at least one auxiliary bone anchor can be driven to extend across a facet plane of the vertebral level and, when coupled in a second configuration, each auxiliary bone anchor received within the wing can be driven to conform to the vertebral level.

Connector assemblies, systems, and methods thereof. An articulating connector has a first end that clamps to a first rod in an existing construct and a second end having a second end that clamps to a second rod in a new construct or such that the new construct can be extended from the existing construct. In the case of different sized constructs used in different areas of the spine, an articulating connector has a first end that clamps to a first rod in a new construct having rods of a first size and a second end having a second end that clamps to a second rod in a new construct having rods of a second size. The clamping portions are capable of translating and rotating with respect to each other.

An adjustable articulating spinal rod system including a first elongated element secured to a first bone, a second elongated element secured to the spine, and an articulating joint connecting the first and second elongated elements. The articulating joint including a first movable joint, a second movable joint, and at least one locking mechanism. The first movable joint is coupled to the first elongated element and the second movable joint which is also coupled the second elongate element. The first and second movable joints are configured to allow polyaxial movement and rotation of the first elongated element with respect to the second elongated element. The at least one locking mechanism immobilizes the first and second movable joints in the locked position to secure the first elongate element in a position relative to the second elongate element and allow movement and rotation in an unlocked position.

The present application discloses transverse connectors that are connectable to first and second rod members that extend along a length of the spine. The transverse connectors are capable of gripping first and second rod members that are at different distances relative to one another, as well as at non-parallel angles relative to one another. In some instances, the first and second rod members can be bottom-loaded into the transverse connectors, while in other instances, the first and second rod members can be side-loaded into the transverse connectors.

Bone anchor assemblies are disclosed herein that can provide for improved fixation as compared with traditional bone anchor assemblies. An exemplary assembly can include a bracket or wing that extends down from the receiver member and accommodates one or more auxiliary bone anchors that augment the fixation of the assembly's primary bone anchor. Another exemplary assembly can include a plate that is seated between the receiver member and the rod and accommodates one or more auxiliary bone anchors that augment the fixation of the assembly's primary bone anchor. Another exemplary assembly can include a hook that extends out from the receiver member to hook onto an anatomical structure or another implant to augment the fixation of the assembly's primary bone anchor. Surgical methods using the bone anchor assemblies described herein are also disclosed.

The present invention addresses rod rotation and slippage inside the tulip rod channel(s), as well as forcible rod bending as the spine and musculature bias towards a deformity, for example. The present invention provides a stabilization rod that, fundamentally, includes at least one flat surface on at least one side of the construct, this flat surface engaging a corresponding flat surface associated with the head body, set screw, or locking cap. Multiple flat surfaces may, of course, be used. The stabilization rod may also include one or more ridges and/or one or more keyed channels that is/are engaged by the head body, set screw, or locking cap.

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.

An orthopedic anchoring system for attaching a spinal stabilization system and concomitantly fusing a sacroiliac joint is disclosed that includes a delivery tool and an implant assembly for insertion into a joint space of a sacroiliac joint. The implant assembly may be secured using anchors inserted through bores within the implant body and into the underlying sacrum and/or ilium. The implant body may also include an attachment fitting reversibly attached to a guide to provide attachment fittings for elements of the spinal stabilization system. The implant assembly may be releasably coupled to an implant arm of the delivery tool such that the implant arm is substantially aligned with the insertion element of the implant assembly. An anchor arm used to insert the anchor may be coupled to the implant arm in a fixed and nonadjustable arrangement such that the anchor is generally aligned with a bore within the implant assembly.

Methods of correcting a spinal deformity, including securing a first rod on a first side of a spine, securing an anchor on a second side of a spine, securing a lateral coupling between the rod and the anchor, translating and/or derotating the spine and securing a second rod on a second side of the spine to provide secondary stabilization to the spine.

A method of surgically treating a patient suffering from severe pain and disability of the low back and buttock by stabilizing the patient's spinal column to their pelvis with an implant system including surgical tools and an implant designed to prevent movement between the sacrum and the ilium while being able to attach to a spinal fusion rod which connect to pedicle screws implanted in the bones of the spine of the patient in order to offer lasting relief of the patient's symptoms. The system is designed to address complications in adult spinal deformity by optimizing spinopelvic fixation via-a-vis the unique biomechanics of the SI joint. The sacropelvic system is a surgical solution which provides an additively manufactured implant at the base of the spine employing an S2AI trajectory while utilizing assisting technologies including surgical navigation and intraoperative neurophysiological monitoring.
