Intervertebral spacer assemblies, systems, and methods thereof. A method of insertion includes inserting an intervertebral spacer and plate together using an insertion tool and, upon removal of the insertion tool, the intervertebral spacer and plate are no longer considered connected/coupled and act as separate components.

An expandable implant is disclosed. The expandable implant includes a base member having a top surface and a bottom surface opposite the top surface, and an adjustable member adjustably coupled to the base member and movable between a first, collapsed position, and a second, expanded position. The adjustable member has a top surface and a bottom surface opposite the top surface. The top surface of the adjustable member and the bottom surface of the base member form a first angle while the adjustable member is in the first, collapsed position, and the top surface of the adjustable member and the bottom surface of the base member form a second angle while the adjustable member is in the second, expanded position. The first angle is different from the second angle.

An implant includes a first support, a second support rotatably coupled to the first support along a distal end of the implant, and a control assembly configured to move the implant between at least a first, collapsed orientation and a second, expanded orientation, the control assembly includes a control driver coupled to the first support and comprising a head and a shaft, the control driver configured to control relative movement between the first support and the second support, a control member configured to move along the shaft of the control driver, and a first linkage hingedly coupled to the control member and the second support, wherein movement of the control member causes the first support to move relative to the second support.

The present disclosure provides for spinal implants and plates including, for example, expandable plates deployable between a contracted position and an expanded position. The expandable plate may include an expandable body including a first portion and a second portion. The first portion may include a receiving cavity facing the proximal end, and a first through aperture extending in the proximal-to-distal direction. The second portion may include a lower end having a size and shape that corresponds to the receiving cavity, and a second through aperture extending in the proximal-to-distal direction. The expandable plate may include a locking screw and a nut. In at least some embodiments, in a locked position, the locking screw extends through the first through aperture and second through aperture, and is secured to the nut. In various embodiments, in an expanded position the first portion and second portion are farther away from one another relative to a contracted position.

The present invention relates generally to a prosthetic spinal disc for replacing a damaged or degenerated disc between two vertebrae of a spine. The present invention also relates to prosthetic spinal disc designs that have either or both interlocking and magnetic components.

A surgical implant system includes a surgical implant for securing adjacent vertebrae of a spine to each other. The surgical implant includes a spacer having at least one implant eyelet. The surgical implant system also includes at least one vertebral anchor configured for insertion through the at least one implant eyelet to fasten the surgical implant to the spine. The vertebral anchor has a tip portion, a head portion, an elongate shank extending from the head portion, and an elongate fin extending from the head portion and along a surface of the elongate shank. The elongate shank and the elongate fin form a generally t-shaped cross-section.

An implant includes a plurality of anchoring members and an interbody device. The interbody device includes a front, a rear, a first lateral side, a second lateral side, a central cavity, and a plurality of bores each configured to receive the plurality of anchoring members. The interbody device further includes a porous portion and a solid portion, the solid portion having a higher density than the porous portion. The solid portion substantially surrounds the porous portion on the lateral outer portions of the front, rear, first lateral side, and second lateral side.

Methods and systems for treating a spinal joint with a facet joint replacement. The prosthesis can include a first component having a first articulating surface and a second component having a second articulating surface. The first component is attached to a superior articulating facet and the second component is attached to an inferior articulating facet. The first articulating surface and the second articulating surface articulate with each other and allow for multiple degrees of movement of the facet joint without fusing the joint.

A hollow bone enclosure (16), of resorbable polymer, such as poly lactic or poly glycolic acid. The hollow bone enclosure comprises an inner contact portion (18), for insertion into a bone defect (not shown) and arranged to make an intimate fit with the surface of the defect, and an outer closure portion.

A methodology for grafting together adjacent bony structures is provided using an implant device having an endplate with an inner disc portion and outer ring portion spaced from the inner disc portion by a connecting wall disposed there between. An endplate interior surface includes a retaining structure for securing the endplate to one of the bony structures, and endplate an exterior surface has an integrally formed socket. A ball-joint rod has a longitudinally extending body and an end, and at least a portion of the ball-joint rod end is curvilinear in shape. The curvilinear ball-joint rod end is rotatably disposed in the endplate socket to fixedly interconnect the bony structures.
