The present invention relates to a method of inserting an implant comprising providing an expandable vertebral implant. The method further may comprise providing an angling inserter tool. The angling inserter tool comprises a handle portion, a base portion, and a tip assembly, the base portion being disposed between the handle portion and the tip assembly. The method further may comprise distally advancing a central shaft of the tip assembly with rotation into an opening in the expandable vertebral implant to secure the angling inserter tool to the expandable vertebral implant. The method further may comprise positioning the expandable vertebral implant in a patient's spine. The method further may comprise for causing the tip assembly to angulate with respect to a longitudinal axis of the angling inserter tool, wherein the internal shaft is coaxial with an outer cylinder of the base portion.

An implant or endoprosthesis suitable to be implanted in human or animal tissue includes two (or more than two) parts to be joined in situ. Each one of the parts includes a joining location, the two joining locations facing each other when the device parts are positioned for being joined together, wherein one of the joining locations includes a material which is liquefiable by mechanical vibration and the other one of the joining locations includes a material which is not liquefiable by mechanical vibration and a structure (e.g. undercut cavities or protrusions) suitable for forming a positive fit connection with the liquefiable material. The joining process is effected by pressing the two device parts against each other and by applying ultrasonic vibration to one of the device parts when the two parts are positioned relative to each other such that the two joining locations are in contact with each other.

Expandable fusion devices, systems, and methods. The expandable fusion device includes one or more integrated deployable retention spikes configured to resist expulsion of the device when installed in the intervertebral disc space. The implant may include upper and lower main endplates, an actuator assembly configured to cause an expansion in height of the upper and lower main endplates, and a sidecar assembly including a sidecar carrier, an upper carrier endplate pivotably coupled to an upper spike, and a lower carrier endplate pivotably coupled to a lower spike such that forward translation of the sidecar carrier pushes against the upper and lower carrier endplates, thereby deploying the upper and lower spikes.

An improved cage that has an anchoring system and method of use thereof. The anchoring system has movable/expandable jaw portions that can expand vertically (i.e., upward and downward relative to the respective superior and inferior surfaces of the cage) so that the cage can be more securely implanted in position. The superior and inferior expandable portions of the anchoring system move vertically by the rotation of one or more spindles that is incorporated in the jaw mechanism (and/or by the rotation of a lead screw that is incorporated in the cage). In some embodiments, the medical implant (such as a cage) is itself non-expandable (i.e., the height of the medical implant does not change). In other embodiments, the medical implant (such as a cage) can be expanded independently of the anchoring system.

According to some embodiments, a method of inserting a lateral implant within an intervertebral space defined between an upper vertebral member and a lower vertebral member includes creating a lateral passage through a subject in order to provide minimally invasive access to the intervertebral space, at least partially clearing out native tissue of the subject within and/or near the intervertebral space, positioning a base plate within the intervertebral space, wherein the base plate comprise an upper base plate and a lower base plate and advancing an implant between the upper base plate and the lower base plate so that the implant is urged into the intervertebral space and the upper vertebral member is distracted relative to the lower vertebral member.

An implant is provided for performing spinal fusion. The implant includes an implant body having a leading side and a trailing side at opposing ends along a longitudinal axis. Between the leading side and trailing side are an upper surface, a lower surface, an anterior side, and a posterior side. At least one keel structure is provided extending from the implant body for penetration into an adjacent vertebral body. A trial sizer and keel cutter may be utilized to form keel channels within the vertebral body to receive the keel structure.

Expandable intervertebral spacer system having a top plate and a bottom plate which are separated and held apart a changeable distance forming a cage. The plates are held apart by four locking mechanisms in the cage at or near the corners or the periphery of the plates, leaving the cavity of the cage substantially unobstructed. Each locking mechanism is made of two saw-toothed posts that cooperate to lock the top plate a desired distance from the bottom plate. The saw-tooth posts are biased against each other with a spring. Once the spacer is implanted in a patient with a removable insertion tool, the top and bottom plates are forced apart incrementally, one saw tooth at a time, in a ratchet-like motion, using a removable expansion mechanism. Optionally, each stanchion is surrounded by a sheath to prevent bone particles and other debris from interfering with the mating of the saw teeth.

The present disclosure relates to a spinal fusion impactor tool that includes an attachment means for securing an implant device to the distal end of the tool, a means for adjusting the angle of the distal head relative to the handle to better position the implant for introduction into the implant site, means for remotely releasing the implant device at the distal end and a clamp device on the shaft of the tool to secure tabs, attachments and other devices. The impactor tool is preferably used in conjunction with implantation of an intervertebral fusion cage that is equipped with shims having tabs or other removing means, but may also be used to introduce, for example, an implant, graft, fusion device, wedge or distractor device into any joint space or bony region in preparation for implantation.

An implant for insertion between vertebral bodies of the spinal column, with a main body which is formed along a longitudinal axis and at least one end of which an attachment plate with a contact surface for attachment to an adjacent vertebral body is disposed, which plate is mounted on main body pivotably about a pivot axis, arranged substantially perpendicular to the longitudinal axis, and which can be fixed at an angle relative to it or relative to the longitudinal axis. The main body is assigned at least one clamping element. The attachment plate has a clamping surface on a side facing the main body, and the clamping element is movable between a pivot configuration, in which the attachment plate is pivotable, and a clamping configuration, in which the angle and thereby the attachment plate are fixed by an interaction of the clamping element with the clamping surface.

Humeral prosthetic implants, systems, kits and methods of forming and using the humeral prosthetic implants, systems and kits are disclosed. The humeral prosthetic implants include proximal cup portions and distal stem portions, wherein the proximal cup portion is joined to the distal stem portion at a desired offset and/or angle configured based on an analysis of the humeral diaphysis and/or metaphysis offset in a patient. The humeral prosthetic implants may also include an adapter configured to join the proximal cup component with the stem component, wherein the adapter is configured to join the stem component to the stemless cup at a desired offset and/or angle.
