Abstract: Disclosed are devices, systems and/or methods for use in the surgical treatment of vertebrae and/or other bones, particularly implants and/or related devices comprising silicon nitride in some of all of the implant or device body, including portions, layers and/or surface coatings thereof, for use in spinal surgeries and/or other orthopedic procedures.

Abstract: An expandable bi-dimensional intervertebral implant for an intervertebral fusion is provided. The implant includes a first hinge arm, a second hinge arm connected to the first hinge arm, and a translation member movable relative to the first hinge arm and the second hinge arm between an initial position and an engaged position. The second hinge arm is movable between a primary position and a secondary position relative to the first hinge arm. In the engaged position, the translation member biases the first hinge arm to move from a first position to a second position and biases the second hinge arm to move between a first position and a second position.

Abstract: Disclosed are devices, systems and related surgical methods including implantable devices having a plurality of osteo-inductive, osteoconductive and/or osseointegrative surface features that may be useful in joint and/or bone replacement implants used in spinal surgeries, dental surgeries and/or other orthopedic and/or general surgical procedures.

Abstract: Disclosed are devices for the fixation and support of vertebrae, particularly spinal implant devices formed from modular components of different materials.

Abstract: A bone fixation system includes a bone fastener and a tower including a modular engagement feature therebetween, the tower having at least one flexible section and at least one rigid section to accommodate and/or mitigate tower interference and/or collision during surgical procedures. The distal section can desirably be separated and/or detached from the tower to function as a head locking unit of the bone fixation assembly, with the detached distal section capable of accommodating set screws, fixation rods and/or other spinal hardware.

Abstract: Disclosed are intervertebral devices for insertion between and/or adjacent to vertebrae of a patient, incorporating apertures for fastening devices which include fastener locking and/or retaining elements.

Abstract: Disclosed are devices, systems and/or methods for use in the surgical treatment of vertebrae and/or other bones, in particular elongated systems and devices including flexible connecting members than can rigidified in a desired manner during a surgical procedure to provide corrective forces to the spine.

Abstract: Disclosed are devices for the fixation and support of vertebrae, particularly adjustable spinal implant devices.

Abstract: A bone fixation system includes a bone fastener and a tower including a frangible or detachably linked distal section with a thread formed on an inner surface thereof, the tower having at least one flexible section and at least one rigid section to accommodate and/or mitigate tower interference and/or collision during surgical procedures. The distal section can desirably be separated and/or detached from the tower to function as a head locking unit of the bone fixation assembly, with the detached distal section capable of accommodating set screws, fixation rods and/or other spinal hardware.

Abstract: An intervertebral cage structure that comprises a main body having a first surface and a second surface located opposite to the first surface, a first plate disposed on the first surface of the main body, a second plate disposed on the second surface of the main body, and an opening formed at a center portion of the intervertebral cage structure and extending from the first plate to the second plate via the main body, wherein at least one of the first and second plates comprise non-parallel undercut portions.

Abstract: An orthopedic assembly is described that comprises an orthopedic device, an anchor, and a locking mechanism. The orthopedic device can be a plate member having an aperture that is configured to receive the anchor. The anchor can include a head, neck and shank portion. The head portion can include a plurality of arms separated by grooves that are capable of splaying. The assembly is configured such that when the locking mechanism is inserted into the head portion, this causes expansion of the arms of the head. This expansion locks and secures the anchor to the orthopedic device. Various instruments are provided that can deliver the locking mechanism to the anchor, and can provide impact to lock functionality.

Abstract: Disclosed are laminoplasty devices and systems, kits that include such laminoplasty devices or systems or components thereof; and methods of assembling and using such laminoplasty devices and systems. In particular, articulating laminoplasty devices are provided that allow lamina plates to be adjusted angularly and transitionally with respect to a cage connecting the lamina plates. Also provided are laminoplasty plates that are configured so as to be assembled with a bone graft housing, and which provide an opening configured to facilitate bone graft insertion into the housing. Further provided are expandable laminoplasty fixation systems that include a lateral mass plate, a lamina plate and a set screw that when screwed and unscrewed, allows one to contract and expand the plates with respect to one another.

Abstract: A cervical spine spacer includes a spacer body configured to be disposed between adjacent cervical vertebrae in the cervical spine and to maintain a desired spacing between the adjacent cervical vertebrae. The cervical spine spacer also includes a channel passing completely through the spacer body from a first surface of the spacer body to a second surface of the spacer body and a fastener configured to pass through the channel. At least one of the first surface and the second surface is configured to contact one of the adjacent cervical vertebrae and the channel is sized to accommodate the fastener passing through the channel at a plurality of angles.

Abstract: An expandable intervertebral implant for an intervertebral fusion is provided. The implant includes a first endplate, a second endplate, a translation member and an auger mounted to the translation member and extending through the second endplate. The first endplate includes a sloped anterior face and a sloped posterior face. The second endplate includes a posteriorly facing sloped surface for matingly engaging the sloped anterior face of the first endplate. The translation member includes an anteriorly facing sloped surface for matingly engaging the sloped posterior face of the first endplate.

Abstract: Disclosed are devices, systems and/or methods for use in the surgical treatment of vertebrae and/or other bones, particularly bone screws having features and/or attributes that allow secure fixation of the device to the bone and prevention and/or inhibition of undesirable loosening and/or “back-out” of the screw body from a targeted surgical site.

Abstract: The invention relates to a modular anchoring adaptor that engages with existing features of commercially available ALIF cages to help eliminate migration and/or anterior expulsion cause by the instability of the spine, such as lordosis. Such modular adaptor will mate or engage with existing features to enhance anchoring within the vertebral disc space, which space is limited and a low-profile should be maintained.
