Anchoring devices, anchoring systems for intervertebral implants, intervertebral implants, and instruments and methods for implanting implants are disclosed. In preferred configurations, these various objects share the feature of comprising or cooperating with an anchoring device having a body comprising at least one curved plate elongated along a longitudinal axis, designed to be inserted through a passage crossing at least a part of implant, in order to penetrate into at least one vertebral endplate and attach implant onto this vertebral endplate by means of at least one stop retaining the implant, characterized in that the body comprises at least one longitudinal rib on at least a part of at least one of its faces, said rib being designed to cooperate with a groove made in passage of implant. In some preferred configurations, anchoring device comprises withdrawal stops or latches, and/or means for withdrawing the anchor from an inserted position.

An orthopedic tibial prosthesis includes a tibial baseplate with features designed for use with small-stature knee-replacement patients. The tibial prosthesis may include a shortened tibial keel, tibial keel fins which define a large angle with respect to a longitudinal axis of the keel, and/or tibial keel fins which extend along less than the entire longitudinal extent of the keel.

Implants, devices, systems and methods for maintaining, correcting and/or fusing joint deformities are disclosed. The implant including a first member, a second member, and a coupling member with a first end and a second end, wherein the first end engages the first member and the second end engages the second member. Methods of using the implants for maintaining, correcting and/or fusing joint deformities are also disclosed.

A humeral head assembly is provided that includes an articular body and a coupler. The articular body includes a coupling portion disposed on a side of the articular body opposite an articular surface. The coupling portion includes a continuous zone of eccentricity adjustment. The coupler portion optionally includes one or more than one discrete position site. The coupler includes a first portion and a second portion opposite the first portion. The first portion is configured to mate with the coupling portion and the second portion is configured to mate with another member of a joint prosthesis. A coupling portion with the continuous range of eccentricity adjustment can be provided on a bone anchor and the eccentricity of another component can be selected by motion of a coupler, such as a tray for reverse humeral assemblies, along the coupling portion of the anchor.

A bone graft delivery system and method for using same to deliver graft material into a surgical site. The system includes an interbody implant having a securing site disposed on a surface of the implant and a holder having an elongated, hollow handle including a distal end. The distal end of the holder is configured to removably engage the securing site of the interbody implant to secure the interbody implant to the distal end of the holder until such time as a user desires to disengage the holder from the interbody implant. The interbody implant may be a cage implant having opposing anterior and posterior surfaces, opposing first and second lateral surfaces, and opposing top and bottom surfaces, wherein the top surface comprises a first aperture and the bottom surface comprises a second aperture, the posterior surface comprising a third aperture, the first, second, and third apertures all linking to a main cavity, the main cavity generally extending between the top surface and the bottom surface.

Implants, devices, systems and methods for maintaining, correcting and/or fusing joint deformities are disclosed. The implant including a first member, a second member, and a coupling member with a first end and a second end, wherein the first end engages the first member and the second end engages the second member. Methods of using the implants for maintaining, correcting and/or fusing joint deformities are also disclosed.

Stand-alone interbody fusion devices for engagement between adjacent vertebrae. The stand-alone interbody fusion devices may include frames and one or more endplates coupled to the frame. The frame 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.

Expandable spinal implants, systems and methods are disclosed. An expandable spinal implant may include a first endplate, a second endplate, and a moving mechanism that is operably coupled to the first and second endplates. The moving mechanism may include a wedge, a first sliding frame and a second sliding frame disposed on opposite sides of the wedge, a screw guide housing a rotatable first set screw and a rotatable second set screw opposite the first set screw. The first set screw may be operably coupled to the second sliding frame and the second set screw may be operably coupled to the wedge. The moving mechanism may operably adjust a spacing between the first and second endplates upon simultaneous rotation of the first and second set screws and operably adjust an angle of inclination between the first and second endplates upon translating the first set screw or second set screw.

A fusion cage has a first component that defines an outside surface that is configured to engage a vertebral endplate, and an interior surface. The fusion cage has a second component that defines first and second opposed surfaces. One of the first and second opposed surfaces can mate with the interior surface of the first component. The fusion cage can include vertical and lateral throughholes adapted to enhance fusion.

Disclosed are modular anchoring adaptors that can engage with existing features of various spinal cages to help eliminate migration and/or anterior expulsion cause by the instability of the spine, such as lordosis. Such modular adaptors will desirably mate or engage with existing features to enhance anchoring within the vertebral disc space.
