Abstract: A method of implanting an intervertebral spacer may include positioning the intervertebral spacer within an intervertebral space defined by adjacent vertebral bodies. The intervertebral spacer may include a plurality of bores, and each of the plurality of bores may be configured to receive either a linear fastening element or a curvilinear fastening element. The method also may include selecting a first fastening element from a group including linear fastening elements and curvilinear fastening elements, and inserting the first fastening element into a first bore of the plurality of bores such that the first fastening element is inserted into one of the adjacent vertebral bodies to secure the intervertebral spacer within the intervertebral space.

Abstract: Stand-alone interbody fusion devices for engagement between adjacent vertebrae. The stand-alone interbody fusion devices may include a spacer or endplates and one or more inserts, members, or frames coupled to the spacer or endplates. The inserts, members, or frames may be configured and designed to provide the apertures which are designed to retain bone fasteners, such as screws or anchors, and secure the implant to the adjacent vertebrae.

Abstract: A surgical instrument includes a housing, an outer shaft, an inner shaft, a trial sizer, a rod, and a head. The outer shaft is operatively coupled with the housing such that rotation of the housing causes axial displacement of the outer shaft. The outer shaft includes a keel cutter configured to form a channel in a vertebral body. The inner shaft disposed within the outer shaft. The trial sizer is configured to be received in intervertebral space. The trial sizer includes a pair of wings transitionable between a retracted position and an extended position in which the pair of wings extends transversely outward. The head is connected to the rod, wherein the head is operatively coupled with the pair of wings such that axial displacement of the rod causes transition of the pair of wings between the retracted and extended positions.

Abstract: Embodiments of devices and methods of correcting vertebral misalignment, including, e.g., spondylolisthesis, are disclosed. In one embodiment, a vertebral implant may include an assembly configured to be secured to a first vertebral body, wherein the assembly includes a frame made of a first material and at least one end plate made of a second material different than the first material; a reducing plate configured to be slidably received over the central portion, wherein the reducing plate is configured to be secured to a second vertebral body; and an actuator configured to move the reducing plate relative to the frame.

Abstract: A spinal implant configured for positioning within a space between adjacent vertebral bodies includes an upper end plate including an outer surface extending between first and second end surfaces and opposed side surfaces. The outer surface includes a first convex profile extending between the first and second end surfaces and a second convex profile extending between the opposed side surfaces. The first convex profile and the second convex profile have different curvatures. The spinal implant further includes a lower end plate and a core disposed between the upper and lower end plates and coupled thereto. A method of assembling a spinal implant and a method of performing spinal surgery are also disclosed.

Abstract: Stand-alone interbody fusion devices and corpectomy devices suitable for use with an oblique implantation. The stand-alone interbody fusion devices may include a spacer having a substantially U-shaped body and a plate coupled to the spacer. The overall shape of the implant is asymmetrical such that a median plane, an oblique plane, or both planes divide the spacer and the plate into two asymmetrical halves. The implants are shaped and configured to allow for an oblique or anterolateral approach to the spine or an oblique corpectomy.
