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.

Zero-profile interbody spacer and coupled plate assembly

An extender system is configured to couple a vertebral bone anchor that has been previously implanted in a vertebra, or is newly implantable in a vertebra, to an adjacent bone, which can be an additional spinal level or an occiput, for example. The extender system includes an extension member having a body and an engagement member coupled to the body. The extension member defines an aperture extending through the engagement member. A screw is configured to attach the extension member to the vertebral bone anchor. The extension member can be fastened to the adjacent bone.

Revision connector for spinal constructs

An implant for insertion into the disc space between vertebrae. The implant including a spacer portion, a plate portion coupled to the spacer portion, a plurality of bone fixation elements for engaging the vertebrae and a retention mechanism for preventing the bone fixation elements from postoperatively uncoupling from the implant.

An intervertebral implant frame that is configured to be attached to a spacer body can include a pair of arms that extend longitudinally from a support member such that the arms extend substantially around the spacer body. The arms may be configured to expand, crimp, or otherwise engage the spacer body to thereby hold the spacer body to the frame. The spacer body may be made from bone graft.

Intervertebral implants, systems, and methods of use

A polyaxial bone anchor has a locking element shaped and configured to allow an anchoring member (e.g., a screw or hook) to polyaxially rotate at large angles about a central axis of the bone anchor before compression locking the anchoring member within an anchor head.

A posterior vertebral plating system comprising a plate and a plurality of attachment members. The plate has a plurality of holes extending through the plate from an upper surface to a lower surface, and the plate is configured to extend along the posterior side of at least two vertebrae adjacent at least one boney structure of each of the vertebrae. The holes are spaced in such a way that a first plurality of holes is positionable over a boney structure of a first vertebra to define a plurality of fixation points to the first vertebra and a second plurality of holes is positionable over boney structure of a second vertebra to define a plurality of fixation points to the second vertebra. The attachment members are insertable through the holes of the plate and into the boney structure of a corresponding vertebra to fix the plate to the vertebra.

A method and device for inserting screws into a patient, such that when the device is removed the device does not stick to the screw. The device, being a push-off driver, may have a handle, an inner driver, and a threaded driver sleeve having a button mechanism and a plurality of spheres, and an inner sleeve. The method includes the steps of assembling a push-off driver attaching a bone screw to the push-off driver inserting the bone screw and detaching the bone screw from the driver by unthreading the threaded driver sleeve from the polyaxial screw which causes the spheres in the recess of the inner driver to back up against the start of the recess and causing the threaded driver sleeve to 'push-off' the polyaxial screw from the inner driver.
