A spine implant for a TLIF surgical procedure is configured to be guided 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 pivoting 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 an opening in and end of the cage and a groove in the pivot 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.

A surgical instrument assembly includes a support frame system, and a surgical tool engageable with the support frame system. The support frame system is adapted for providing a surgical tool attachment and articulation locus that is maintained during the course of a surgical procedure to direct a fixed and repeatable delivery path for introduction and manipulation of one or more surgical instruments and implants at a surgical site in or on the patient's anatomy. The delivery path can be substantially curvilinear along an arc that is defined by a radius of curvature and length defined by the surgical tool, and a predetermined range of articulation of the tool at the articulation locus.

The biocompatible lattice structures and implants disclosed herein have an increased or optimized lucency, even when constructed from a metallic material. The lattice structures can also provide an increased or optimized lucency in a material that is not generally considered to be radiolucent. Lucency can include disparity, maximum variation in lucency properties across a structure, or dispersion, minimum variation in lucency properties across a structure. The implants and lattice structures disclosed herein may be optimized for disparity or dispersion in any desired direction. A desired direction with respect to lucency can include the anticipated x-ray viewing direction of an implant in the expected implantation orientation.

The present disclosure includes implant systems, devices, and implants. The interbody spacers including a first endplate, a second endplate, and a coupling member coupled to and extending between the first endplate and the second endplate. Methods of using the interbody spacers are also disclosed.

Implants and instruments for providing an ideal trajectory for the insertion of instruments and screws during implantation of an interbody implant in a spinal surgery are disclosed.

An implant including first and second end plates, each of which defines at least one anterior ramped surface and at least one posterior ramped surface. A posterior actuator is positioned between the first and second end plates and has guiding ramp surfaces which correspond with the posterior ramped surfaces. An anterior actuator is positioned between the first and second end plates and guiding ramp surfaces which correspond with the anterior ramped surfaces. An actuator assembly extends between the posterior actuator and the anterior actuator and is configured to selectively move the posterior actuator and the anterior actuator simultaneously, move posterior actuator independently of the anterior actuator, or move the anterior actuator independently of the posterior actuator.

Spinal implants that are configured for a minimally invasive approach to a patient's intervertebral disc space, optimized to avoid blood vessels and nervous tissue, maximizing endplate coverage and promoting sagittal balance, are provided. Insertion and fixation can be accomplished through a narrow access window, thereby allowing better access to more spinal levels while being less invasive than other approaches. The spinal implants may facilitate fusion, and include visualization features to assist in the implantation and verify proper placement and vary segmental angle of lordosis. Methods of implanting the spinal implants to treat a patient's spine are also disclosed.

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.

This disclosure describes spinal implants with anchoring elements including an aperture for delivery of injectable materials. In one aspect, a spinal implant includes a body defining one or more injection ports and one or more channels, the one or more injection ports configured to receive flowable material and to provide the flowable material to the one or more channels; and one or more anchoring elements protruding from a surface of the body, the one or more anchoring elements each defining an aperture coupled to the one or more channels and configured to receive the flowable material from the one or more channels and to provide/output the flowable material from the aperture.

A spinal implant includes a body having opposite first and second end walls and opposite first and second side walls. The side walls each extend from the first end wall to the second end wall. A first cap is coupled to top ends of the walls. A second cap is coupled to bottom ends of the walls. The implant includes an opening extending through the caps such that the first cap defines a first ledge extending from the walls to the opening and the second cap defines a second ledge extending from the walls to the opening. Systems and methods of use are disclosed.
