An elbow prosthesis includes a stem structure and an articulating component. The stem structure is operable to be positioned in a bone of a joint and includes a stem portion and a C-shaped body portion. The stem portion is operable to be positioned in the bone. The C-shaped body portion includes a first articulating surface bound by a medial wall and a lateral wall. The medial and lateral walls are separated by a first distance. The articulating component includes a second articulating surface positioned between a medial side surface and a lateral side surface. The medial and lateral side surfaces are separated by a second distance that is less than the first distance. The second articulating surface is configured to slidably communicate in a medial/lateral direction along the first articulating surface of the C-shaped body portion.

This set comprising: an anatomic articulating member, having a concave articulating surface intended to articulate with a complementary humeral implant and having an anatomic coupling feature, a reversed articulating member, having a convex articulating surface intended to articulate with a complementary humeral implant and having a reversed coupling feature that is shaped differently from the anatomic coupling feature, and an anchorage member intended to be anchored in a human glenoid, the anchorage member including a body which defines a proximodistal axis and has inner bore extending along the proximodistal axis, the body being provided within the inner bore with both an inner first feature that is designed to cooperate with the anatomic coupling feature when the anatomic coupling feature is introduced within the inner bore, so as to fixedly couple the anchorage member with the anatomic articulating member, and an inner second feature that is designed to cooperate with the reversed coupling feature when the reversed coupling feature is introduced within the inner bore, so as to fixedly couple the anchorage member with the reversed articulating member, the first feature and the second feature being distinct from each other.

The body is operable to be axially introduced into the glenoid before being coupled indifferently with one or the other of the anatomic and reversed articulating members.

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.

An interbody spinal implant including a body having a top surface, a bottom surface, opposing lateral sides, and opposing anterior and posterior portions. At least a portion of the top surface, the bottom surface, or both surfaces has a roughened surface topography including both micro features and nano features, without sharp teeth that risk damage to bone structures, adapted to grip bone through friction generated when the implant is placed between two vertebrae and to inhibit migration of the implant. The roughened surface topography typically further includes macro features and the macro features, micro features, and nano features overlap. Also disclosed are methods of using such implants and processes of fabricating a roughened surface topography on a surface of an implant. The process includes separate and sequential macro processing, micro processing, and nano processing steps.

Intervertebral spacer assemblies, systems, and methods thereof. A method of insertion includes inserting an intervertebral spacer and plate together using an insertion tool and, upon removal of the insertion tool, the intervertebral spacer and plate are no longer considered connected/coupled and act as separate components.

Systems for and methods of fusing a sacroiliac joint are provided which may include an implant adapted to be inserted into the joint space defined by the bones of a sacrum and an ilium and a delivery tool for inserting the implant into the sacroiliac joint. The method may include delivering the implant into the SI joint in a first position and transitioning the implant from the first position to a second position in situ. The implant may be configured such that in the second position the implant generally mimics a shape of the joint space of the sacroiliac joint. The implant may further include an actuation mechanism configured to cause the implant to transition from the first position to the second position. The actuation mechanism may include a hydraulic, pneumatic, geared or screwed mechanical arrangement.

A distraction device includes a cage distractor, two distractor blades, an inserter positioner, and a clip inserter. The cage distractor is selectively securable to the two distractor blades and includes two distractor housings moveable relative to one another. The inserter positioner is selectively securable to the two distractor blades and include a center member that is centered between the distractor blades when the inserter positioner is secured to the two distractor blades. The clip inserter is configured to secure a clip to a distal end thereof and is slidable through the center member to secure the clip to a cage distracted by the movement of the two distractor housings away from one another. The clip maintaining the distraction of the cage.

A spinal implant apparatus that is an expandable spacer including features to minimize or eliminate spacer cant or offset during and after completing the expansion process. The spacer includes a top component, a base component in engagement with the top component, and an expansion mechanism arranged to change the top component's position with respect to the base component. The mechanism for causing expansion may be a screw, a cam, a wedge or other form of distracting device. In one embodiment, the expandable spacer includes a base component with a set of towers and a top component with a set of corresponding silos, where the towers and silos are configured to minimize or eliminate tilt of the top component as it extends upwardly from the base component.

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.

The present invention relates to a vertebral system comprising a vertebral implant (2) and a plurality of inserts, said implant being designed to be implanted in a vertebral segment composed of at least two vertebrae and including a body (20) the walls whereof delimit a cavity (23) leading to the outside of the body (20) through at least one opening in at least one of said walls, at least one passage (21) passing through the implant (2) from the periphery to an upper or lower surface to receive a bone-anchoring device (1) capable of anchoring the implant (2) in at least one of said vertebrae, the system being characterized in that it includes at least two inserts selected from among the following inserts: at least one graft insert (3, 3A, 3B, 4, 5A, 5B, 6A, 6B, 6C, 6D, 202, 250) capable of being colonized by bone tissue and/or receiving at least one bone tissue graft and/or at least one substitute; and/or at least one bone-anchoring insert (210) comprising said passage (21) capable of receiving said bone-anchoring device (1).
