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 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 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.

Posterior vertebral plating system

An adjustable intervertebral implant for implantation into a patient's spine in-between first and second adjacent or neighboring vertebrae. The implant may include one or more of the following features: (i) inner and outer members coupled by a radiographically imagable expansion ring, (ii) detachable endplates coupled to the implant via a polygonal press-fit coupling interface that accommodate a range of lordotic endplates to be applied to the implant using any surgical approach, (iii) an interference pre-loaded set screw for selectively locking the height of the construct, (iv) a radiographically imagable marker for determining the expansion of the implant, and (v) an asymmetric thread coupling between the expansion ring and the inner member.

The present invention relates to headed push-in fasteners of the type produced by Penn Engineering & Manufacturing Corp. known as TackPins and TackScrews. More specifically it relates to a Tack Pin or a Tack Screw with a Belleville head that provides the functionality of a Bellville washer without needing a separate part. When installed, the compression of the Bellville shaped head will cause a permanent loading to be applied under the head of the fastener, essentially creating a clamping force to the members being attached.
