Various embodiments of bone ties, bone tie inserters, and methods for treating the spine are provided. The bone tie can include a proximal end and a distal end. The bone tie can include a head section comprising a rounded head. The bone tie can include a neck section extending proximally from the head section. A bone tie inserter for placing a bone tie can also be provided. The bone tie inserter can include a bone tie advancer with a curved surface configured to guide a rounded head of a bone tie. The bone tie inserter can include a bone tie retriever configured to receive the rounded head of a bone tie. The bone tie is configured to pivot and/or rotate within the retriever portion of the bone tie inserter. The method can include forming a lumen in a first bone portion and a second bone portion. The bone tie can be configured to pivot and/or rotate as the bone tie retriever is withdrawn.

Bone tie and bone tie inserter

An implant includes an interbody device having a front, a rear, a first lateral side, a second lateral side, a central cavity, and a plurality of bores extending into the rear of the interbody device, each arced bore being configured to receive an arced anchoring member.

Implant with bone screw retention

The present invention provides an expandable fusion device capable of being installed inside an intervertebral disc space to maintain normal disc spacing and restore spinal stability, thereby facilitating an intervertebral fusion. The fusion device described herein is capable of being installed inside an intervertebral disc space at a minimum to no distraction height and for a fusion device capable of maintaining a normal distance between adjacent vertebral bodies when implanted.

Implant expanding in width before height using a single actuator

A variety of expandable cage improvements are provided. The cages can have a width expansion assembly that operates independently of a height expansion assembly and the wedges and ramps do not need to make contact with each other. Wedges, or movable spacers with pivotal link connections, can be used, and any portion of the cage can be expanded in width or in height in an amount that differs from other portions of the cage to provide any of a multitude of desired cage shapes. Interdigitating fingers, slidable and/or pivoting, are provided to distribute stresses over a vertebral endplate as desired.

Expandable fusion device with independent expansion systems

This disclosure describes example embodiments of rod reduction instrumentation and other rod and vertebrae manipulation instruments. The rod reducers can be used during the installation of a rod based surgical fixation system to help urge the rod into the fixation anchors. The reducers described provide various configurations delivering large reduction distance capabilities, strong controlled reduction coupled with an ability to quickly advance the reducer if desired, and reduction of bulk through the surgical corridor.

Rod reduction assemblies and related methods

Button-suture assemblies which employ a knotted locking mechanism do not maintain tension when securing bone and tissue fragments. A knotless method and device for maintaining tension and providing precise placement of a button-suture assembly during stabilization procedures comprising a locking pin, which mates with a button creating pinch points with increased surface area through which suture can pass from a baseplate through two dedicated openings in the button, one for the first end of the suture and one for the second end of the suture while preventing tension loss during the locking step and therefore allowing for precise placement of the button-suture assembly.

Knotless orthopedic stabilization system

Systems and methods are described for correcting sagittal imbalance in a spine including instruments for performing the controlled release of the anterior longitudinal ligament through a lateral access corridor and hyper-lordotic lateral implants.

Method and apparatus for performing spine surgery

A posterior cervical fixation system including an occipital plate member, a cross connector, a pair of elongated spinal rods and a plurality of polyaxial screws. The occipital plate member configured for fixing to an occipital bone comprises an aperture to receive a bone anchor member to secure the occipital plate member to the occipital bone and at least one rod clamping element dimensioned to receive at least one spinal rod. The cross connector secures the pair of elongated spinal rods to vertebral bodies. The cross connector includes a pair of collet connectors and a cross bar that is configured to secure the pair of elongated spinal rods in a desired distance. Each polyaxial screw has an anchor head associated with a fastening member. The pair of elongated spinal rods is configured to extend along the vertebral bodies between the occipital plate member and at least one of the polyaxial screws.

Posterior cervical fixation system

An expandable implant includes a top support configured to engage a first portion of vertebral bone, a bottom support configured to engage a second portion of vertebral bone, and a control assembly coupled to the top support and the bottom support and configured to control relative movement between the top support and the bottom support. The control assembly includes a control member including a head and a body portion. The head includes a recess and the body portion includes at least one access port in fluid communication with the recess to enable delivery of fluid to an interior of the implant via the recess and at least one access port.

Expandable implant assembly

Spinal fusion device with staged expansion

The disclosure provides a spinal implant having spinal anchors comprising a bone anchor and a receiver configured to securely and polyaxially receive the bone anchor. Further, provided herein are methods for using the spinal implant.

Polyaxial anchor assemblies and related methods

A spine implant (e.g., for a TLIF surgical procedure) is configured to be steered into place during implantation in conjunction with a complementary insertion instrument. The cage of the implant is constrained to a limited range of rotation about a post carried by the cage. The insertion instrument is configured to hold the post while controllably rotating the cage relative to the post in order to angularly position the implant during implantation. Range of rotational motion is controlled by the configuration of a groove in the post. A retaining pin of the implant extends from the cage into the groove of the post to rotationally connect the cage to the post.

Steerable spine implants

Expandable spinal fusion devices, systems, and methods of using them are provided, and they can be inserted in a subject in a collapsed state through a small surgical corridor, and the expand cephalocaudal only, transverse only, or in both directions, in which direction of expansion can also be obtained independently, if desired, after the insertion. These inventions are valuable in reducing risk and surgical complexity, allowing for an on-the-fly selection of a desirable width footprint, a desired control of height expansion through a gradual cephalocaudal expansion, and a desired control of the alignment of the adjacent vertebral bodies. Devices, systems, and methods are also offered to provide a desired control of the contact area desired between the device and the upper and lower vertebral endplates achieved, for example, using an interdigitated endplate system.

Expandable fusion device with interdigitating fingers

An interspinous process device includes a first plate, a second plate, and a transverse member between the first plate and the second plate, wherein the second plate is adjustably coupled to the transverse member. A post is coupled to the transverse member and a spring mechanism is disposed between the post and the first plate. The spring mechanism is configured to provide a preloaded compression force to the first and second plates. Methods of implanting the interspinous process device using an inserter tool are also disclosed.
