Arcuate fixation member

Arcuate fixation members with varying configurations and/or features are provided, along with additional components for use therewith in provided intervertebral implants. The arcuate fixation members may be of different lengths, cross sectional geometries, and/or cross sectional areas. Applications of intervertebral implants utilizing arcuate fixation members are particularly suitable when a linear line-of-approach for delivering fixation members is undesirable.

Tritanium AL Implants and Instrumentation

In some embodiments, the present disclosure relates to a system that includes an insertion tool and a drill guide. The insertion tool includes a body with a distal portion and a distal end. The body has a first engagement feature extending longitudinally along the distal portion and two arms extending longitudinally from the distal end of the body. The drill guide includes two bores and an open faced channel therebetween. The open faced channel includes a second engagement feature slidably engageable with the first engagement feature on the body of the insertion tool. The two bores are adapted for the disposal of a fastener driver tool therethrough.

Arcuate fixation member

Arcuate fixation members with varying configurations and/or features are provided, along with additional components for use therewith in provided fixation systems and intervertebral implant systems. The arcuate fixation members may be of varying lengths, cross sectional geometries, and/or cross sectional areas, and may be configured with various features such as heads configured to accept other fixation system components, tabs to allow arcuate fixation member-in-arcuate fixation member or fixation anchor-in-arcuate fixation member configurations. Applications of fixation systems and intervertebral implants systems utilizing arcuate fixation members are particularly suitable when a linear line-of-approach for delivering fixation members is undesirable.

INTERVERTEBRAL IMPLANTS AND RELATED SYSTEMS AND METHODS
20200155325 · 2020-05-21 ·

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.

Stand Alone Intervertebral Fusion Device

An angled fixation device, such as an angled screw. This angled fixation device may be used by the surgeon to secure a spacer to a spinal disc space. The proximal end portion of the angled fixation device is driven perpendicular to the anterior wall of the spacer, and so is parallel to the vertebral endplates and in-line with the inserter. The distal end portion of the angled fixation device is oriented at about a 45 degree angle (plus or minus 30 degrees) to the vertebral endplate it enters.

Locking system

The orthopedic implant locking system may include an eccentric tibial stem having an engagement rod selectively threadingly engageable with a tibial baseplate, a lock housing securable in rotatable and substantial vertical constrained relation relative to the tibial stem, and an extension lock selectively threadingly engageable with the lock housing and including an inner passage keyed to selectively slidably engage the engagement rod in flush engagement therewith. The extension lock may extend or contract in response to rotational movement of the lock housing simultaneously while the extension lock remains in substantial non-rotatable relation relative to the tibial stem. Engagement of the extension lock with the tibial baseplate may generally vertically and rotationally selectively lock the tibial baseplate with the tibial stem and, based on the threaded spaced relation of the tibial baseplate relative to the tibial stem, linearly and eccentrically axially misalign the tibial stem relative to the tibial baseplate.

Anterior cervical plate
20200038068 · 2020-02-06 ·

An anterior cervical plate system is provided. The plate is configured to receive bone screws for attachment to and immobilization of adjacent vertebrae of the spine. The system includes a cup retained inside a through hole of the plate by a cup retainer. A bone screw is retained inside the cup by a lock that is movable between a locked position and an unlocked position. The cup is permitted to angulate forward and backward with respect to the plate and the bone screw is permitted to angulate conically with respect to the cup to provide a plate system with extreme angulation for the bone screw.

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.

Adjustable Distraction Cage with Linked Locking Mechanisms

A spinal implant which is configured to be deployed between adjacent vertebral bodies. The implant has at least one extendable support element with a retracted configuration to facilitate deployment of the implant and an extended configuration so as to expand the implant and effectively distract the disc space, stabilize the motion segments and eliminate pathologic spine motion. The implant has a minimal dimension in its unexpanded state that is smaller than the dimensions of the neuroforamen through which it typically passes to be deployed within the intervertebral space. The implant is provided with a locking system having a plurality of linked locking elements that work in unison to lock the implant in an extended configuration. Bone engaging anchors also may be provided to ensure secure positioning.
