A bone implant includes at least one bone-engaging surface designed to mate with an implant-engaging surface of a bone. In the preferred embodiment, the bone-engaging surface of the implant includes a wave pattern comprising at least one peak extending in a proximal direction or at least one valley extending in a distal direction. The implant-engaging surface of the bone also includes a matching wave pattern having at least one peak and valley. Upon mating the engaging surfaces, a bone-implant interface may be created wherein the peaks and valleys of the wave patterns are aligned. As a result, there is good surface contact area at the bone-implant interface which helps prevent loosening or rotating of the implant.

The present disclosure relates to flexible porous implant fixation systems. Certain aspects provide flexible porous structures including a helicoidal structure and a plurality of interlocking elements coupled to the helicoidal structure, the helicoidal structure being configured to connect the plurality of interlocking elements. Certain aspects provide a body comprising a porous structure, the body configured to interface with a bone perpendicular to an axis of the bone; and a screw comprising a head, wherein the head is configured to lie within a volume of the body while a portion of the screw extends away from the body, wherein the body is configured to restrict movement of the head within the body along the axis of the bone.

A delivery device includes a guide tool and an impact tool. The guide tool includes an elongate body formed with a longitudinal guide channel, whose inner perimeter is made to complement an outer contour of an implant. The elongate body is formed with a longitudinal impact-tool channel, whose inner perimeter is made to complement an outer contour of the impact tool.

A tool for delivery and/or compaction of bone graft material includes a cannula with an inner lumen extending along a longitudinal axis from a hopper end of the cannula to a delivery tip of the cannula. A hopper with an internal volume for storing bone graft material is connected to the hopper end of the cannula with the internal volume of the hopper in communication with the inner lumen of the cannula for delivery of bone graft material from the hopper to the delivery tip of the cannula. An output shaft within the inner lumen extends along the longitudinal axis. The output shaft includes a helical screw thread extending radially outward from the output shaft toward an inner surface of the cannula. An actuator is connected to the hopper and to the output shaft to drive the output shaft rotationally relative to the hopper and to the cannula.

Disclosed is a spinal complex cage, which includes a cage which is made of a polymeric material, and metal covers which are formed on upper and lower portions of the cage, respectively, in which couplers formed on the metal covers are coupled to coupling grooves formed in the cage, such that the metal covers are detachably coupled to the upper and lower portions of the cage. Accordingly, because the cage and the metal cover are detachably coupled to each other, the manufacturing method is simple, and the metal cover is easily coupled to or separated from the cage, such that the spinal complex cage may be variously and quickly applied even during the surgery in accordance with shapes or intervals between the vertebral bodies, and as a result, a spinal fusion rate is excellent, and the accurate and precise surgical operation is enabled.

The present invention is directed generally to (1) an articulating junction, and articulation method thereof, wherein articulation is facilitated by a plurality of magnetic particles; (2) an articulating junction, and articulation method thereof, wherein the stability and fluidity of the junction is based, at least in part, on the magnetic field(s) of the plurality of magnetic particles; and (3) reducing the resistance to articulation and/or increasing the structural integrity and support, of the articulating junction, via electro-magnetism. Further, the present invention is directed generally to the synergistic combination of magnetic particles and preferred bio-implant-materials and additive-manufacturing methods along with Baker correlation codes. Further, the present invention is directed to an artificial joint for implantation into a living body and methods for constructing such an artificial joint.

Devices and methods for treating one or more damaged, diseased, or traumatized portions of the spine, including intervertebral discs, to reduce or eliminate associated back pain. In one or more embodiments, the present invention relates to an expandable interbody spacer. The expandable interbody spacer may comprise a first jointed arm comprising a plurality of links pivotally coupled end to end. The expandable interbody spacer further may comprise a second jointed arm comprising a plurality of links pivotally coupled end to end. The first jointed arm and the second jointed arm may be interconnected at a proximal end of the expandable interbody spacer. The first jointed arm and the second jointed arm may be interconnected at a distal end of the expandable interbody spacer.
