An interbody implant system for use in the spine includes a base comprising two or more bone contacting surfaces, at least one recess in at least one of the two or more bone contacting surfaces, the recess configured for containing a tooth, a deployable tooth to provide fixation between the base and the anatomy of a subject, a break-away bridge between the tooth and the base for providing a first relative position between the tooth and the base, and a locking mechanism for providing a second relative position between the tooth and the base.

An orthopedic implant which generally includes a frame structure and a porous structure. Both the frame and porous structure at least partially define at least six surfaces which make a three-dimensional profile of the implant. The porous structure is positioned at least partially within the three-dimensional profile.

A system and method for altering bone growth on and within an orthopedic implant that includes an implant body; a plurality of electrodes, wherein each electrode is at least partially embedded in the implant body, and comprises: a set of primary electrodes comprising at least one electrode, wherein a non-embedded segment of each primary electrode is proximal to a bone growth region, a set of secondary electrodes comprising at least one electrode, wherein a non-embedded segment of each secondary electrode is distal to the bone growth region, and wherein the plurality of electrodes are configured to function in a stimulation operating mode, such that a subset of primary electrodes function as cathodes and a subset of secondary electrodes function as anodes; a control system comprising a processor, and circuitry that connects to the plurality of electrodes; and a power system.

An interbody spinal implant including a body portion having a superior side, an inferior side and a lateral side connecting the superior side and the inferior side, at least one of the superior side or the inferior side comprises a bone contacting surface operable to be coupled to an anatomical structure of a patient; and a plurality of uniform features formed in the bone contacting surface, wherein each uniform feature of the plurality of uniform features comprise a planar peak or a round peak and are dimensioned to increase a surface area of the bone contacting surface to promote bone growth.

An interbody spinal cage comprising: a body portion comprising a superior side, an inferior side and at least one lateral side connecting the superior side and the inferior side; and at least one endplate portion coupled to the superior side or the inferior side of the body portion, the at least one endplate portion comprising a unibody structure and operable to be fixedly coupled to an anatomical structure of a patient and decoupled from the superior side or the inferior side of the body portion.

A lumbar interbody fusion device includes a first wing, a second wing, and a bridge. The bridge has an arcuate resting shape and include a first end connected to the first wing, a second end connected to the second wing, and at least one aperture extending through the bridge in a radial direction relative to the arcuate resting shape of the bridge. The bridge is elastically deformable such that a distance between the first wing and the second wing may vary according to elastic deformation of the bridge.

An osteotomy implant includes a first surface extending generally in a first plane and a second surface extending generally in a second plane, oblique to the first plane. The first surface has a perimeter having a first linear edge, a first curve edge connected to the first linear edge, a second linear edge connected to the first curved edge, and a second curved edge connected to the second liner edge.

An implant for insertion into a disc space between vertebrae, wherein the implant includes a spacer portion, a plate portion coupled to the spacer portion, two bone fixation elements for engaging the vertebrae and a retention mechanism for preventing the bone fixation elements from postoperatively backing-out of the plate portion. The retention mechanism may be in the form of a spring biased snapper element that is biased into communication with the bone fixation elements so that once the bone fixation element advances past the snapper element, the snapper element is biased back to its initial position in which the snapper element interfaces with the bone fixation elements. Alternatively, the retention mechanism may be in the form of a propeller rotatable between a first position in which the bone fixation elements are insertable to a second position where the bone fixation elements are prevented from backing-out.

A bone fusion device for insertion between bones that are to be fused together, such as, for example, the vertebrae of a spinal column. The bone fusion device comprises at least one extendable tab and one or more tab extension assemblies. Each tab extension assembly is able to be adjusted in order to individually control the extension or contraction of a side of the tab thereby enabling adjustment of the height and/or angle of the tab with respect to the body of the bone fusion device. Each tab extension assembly is able to be individually adjusted such that the side controlled by each assembly is raised or lowered until the desired tab angle is achieved. The tab is advantageously positioned and angled to correspond to the vertebrae to help brace the device until the bone has fused.

A vertebral insert may include a first linkage, a second linkage, and a third linkage. The first, second, and third linkages may at least partially defining a cavity. The insert may be movable between a collapsed configuration and an expanded configuration, and the movement of the first and second linkages with respect to one another may be configured to reciprocally move the insert between the collapsed and expanded configurations.
