Abstract: An interbody system for implanting between vertebrae, the interbody system comprises a cage having a cage body that includes a graft chamber having a volume that receives graft material, a sagittal wall that forms a portion of the graft chamber, and a wall membrane that forms another portion of the graft chamber. The interbody system may comprise an interbody device that includes an aperture that receives a bone fastener, wherein the wall membrane interacts with the bone fastener. The wall membrane may bend as result of a force applied by the bone fastener to a portion of the wall membrane, thereby providing directional support to the bone fastener and/or forcing graft material from the graft chamber.

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.

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: Spinal fixation apparatus with a first end for selectively flexing to expand in diameter when receiving a head of an engagement member, the engagement member for coupling to a portion of a spine and a flexible sidewall between the first end and a second end, the flexible sidewall to selectively expand in length, between the first end and the second end, when the first end is not in receipt of the head of an engagement member and alternatively to contract in length when the first end is in receipt of the head of the engagement member.

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: Disclosed is a sacro-iliac join fusion system including a block or wedging cage positioned between the sacrum and iliac bone, wherein the block or wedging cage can fit around one or more fixation or axial screws to fasten the block or wedging cage and secure the block or wedging cage to the adjacent pelvic bones to promote fusion and fixation.

Abstract: Spinal fixation system connectors comprising spring cage elements. In some embodiments, an engagement member, such as a bone screw, may be configured to be coupled with and received within a connector body. A spring cage structure may also be configured to be coupled with the connector body. The spring cage structure may comprise a spring configured to be positioned in a relaxed configuration and a flexed configuration, such that the spring defines an opening having a first size in the relaxed configuration and a second, larger size in the flexed configuration to allow the opening to receive and engage a head of the engagement member within the connector body.

Abstract: Disclosed are improved orthopedic tools and methods for use during orthopedic surgical procedures, including joint arthroplasty and joint replacement procedures. More specifically, disclosed herein are improved apparatus for preparing bone and/or soft tissue of the spine and/or other regions for implantation of intervertebral implants.

Abstract: Apparatus and systems relating to spinal implants and instruments for installing such implants. In some embodiments, the system may comprise a spinal implant, an inserter, an intermediary piece, and/or an installation rod. The spinal implant may comprise an at least partially threaded opening configured to receive the installation rod. The opening may be positioned within a fixed wall of the spinal implant, and the opening may comprise a peripheral edge defined by the wall of the spinal implant.

Abstract: An intervertebral implant may include a superior exterior surface, an inferior exterior surface, a first exterior lateral surface, and a second exterior lateral surface. The first and second exterior lateral surfaces may be substantially transverse to the superior and inferior exterior surfaces. The implant may further include a first curved end wall at a first longitudinal extremity of the body. The first curved end wall may include a bore configured to receive a first shaft of a tool. Additionally, the implant may include a second curved end wall at a second longitudinal extremity of the body and an elongated slot extending from a portion of the first curved end wall to a portion of the first exterior lateral surface.

Abstract: An intervertebral device may include a body configured for insertion between adjacent vertebrae of a patient. The body may include a wall having a first surface, a second surface, and a thickness extending between the first and second surfaces. The wall may include a through aperture extending between a first opening on the first surface and a second opening on the second surface. The through aperture configured to receive a fastening element. A recess may be disposed in a side wall of the aperture and may extend into the thickness of the body in a direction substantially transverse to an axis of the aperture. Additionally, at least one offsetting element may be positioned adjacent the through aperture. The at least one offsetting element may be configured to apply a force to the fastening element.

Abstract: Biomedical implants comprising portions made of disparate materials, such as intervertebral implants and related methods and instruments. In some embodiments, the implant may comprise a base portion comprising a first material and a secondary fastener portion comprising a second material having distinct physical properties relative to the first material. The secondary portion may wholly define a front end wall surface of the implant, and the base portion and the secondary portion may collectively define at least one of an upper surface and a lower surface of the implant.
