Implant assemblies, systems, and methods for stabilizing a joint between a superior vertebra and an inferior vertebra may include a plate member coupled to an interbody spacer with at least one fastener that extends superiorly or inferiorly from the implant assembly to anchor within a vertebral body and stabilize the joint. Inserters and methods of insertion may also be included to facilitate fixation of various implant assemblies within the intervertebral space of the joint between the superior vertebra and the inferior vertebra.

A joint replacement implant is disclosed. The implant includes a body having a bone contact surface and an articulation surface. An expandable stem extends longitudinally from the bone contact surface. The expandable stem includes a plurality of flanges. The plurality of flanges are expandable from a first diameter to a second diameter to anchor the implant to a bone.

A surgical implant and a method for the making the surgical implant is provided. The surgical implant includes various granules incorporated into an upper surface and a lower surface of a body portion thereof. The granules can be pressed into the upper surface and the lower surface via physical force using at least one mold portion. The physical force applied by the at least one mold portion can deform and/or extrude the upper surface and the lower surface to impregnate these surfaces with the granules. The granules can provide the implant with bioresorbable and/or mechanically-reinforced properties.

The present invention provides a method for stabilizing a fractured bone. The method includes positioning an elongate rod in the medullary canal of the fractured bone and forming a passageway through the cortex of the bone. The passageway extends from the exterior surface of the bone to the medullary canal of the bone. The method also includes creating a bonding region on the elongate rod. The bonding region generally aligned with the passageway of the cortex. Furthermore, the method includes positioning a fastener in the passageway of the cortex and on the bonding region of the elongate rod and thermally bonding the fastener to the bonding region of the elongate rod while the fastener is positioned in the passageway of the cortex.

An intervertebral implant component of an intervertebral implant includes an outer surface for engaging an adjacent vertebra and an inner surface. A keel extends from the outer surface and is designed to be disposed in a slot provided in the adjacent vertebra. This keel extends in a plane which is non-perpendicular to the outer surface; and preferably there are two of the keels extending from the outer surface which are preferably offset laterally from one another. In another embodiment, an anterior shelf is provided at an anterior end of the outer surface, and this anterior shelf extends vertically away from the inner surface in order to help prevent bone growth from the adjacent vertebra towards the inner surface. Further in accordance with disclosed embodiments, various materials, shapes and forms of construction of the component and/or keel provide various benefits.

A glenoid assembly includes a base component having a humeral-facing side and a scapula-facing side, the base component defining a bearing surface defined on the humeral-facing side, a first peg extending from the scapula-facing side of the base component, the first peg including a first shaft with a first passageway extending through the first shaft, and a second peg extending from the scapula-facing side of the base component, the second peg including a second shaft with a second passageway extending through the second shaft, wherein the first peg and the second peg are positioned in non-parallel orientation with respect to each other.

A spinal implant adapted to be positioned within a disc space between adjacent vertebrae includes a first intradiscal element, a second intradiscal element, and a coupling mechanism. The first and second intradiscal elements include respective first and second outer surfaces adapted to be positioned adjacent an endplate of respective first and second adjacent vertebrae. The first and second intradiscal elements further include respective first and second medial surfaces that are opposite the respective first and second outer surfaces, where the second medial surface is adapted to generally face the first medial surface upon assembly of the first intradiscal element with the second intradiscal element. The coupling mechanism is associated with the first and second medial surfaces and is adapted to provide relative rotational movement between the first and second intradiscal elements in a plane generally parallel with the first and second medial surfaces.

An implant may include a body having a first portion and a second portion and a structural member having a central member curve. In addition, the structural member may be exposed on an outer surface of the implant. Further, the central member curve may include a winding segment, and the winding segment of the central member curve may wind around a fixed path extending from the first portion of the body to the second portion of the body. Also, the central member curve may make one or more full turns around the fixed path. And, the structural member may have a member diameter at the winding segment, wherein the winding segment has a winding diameter corresponding with the full turn around the fixed path and the member diameter is greater than the winding diameter.

An implant may include a body having a leading edge portion, a trailing edge portion, and an intermediate portion. The leading edge portion may include a substantially smooth surface forming a substantial majority of a leading edge surface and the trailing edge portion may include a monolithic structure including at least one receptacle configured to receive an insertion tool. The intermediate portion may include a plurality of elongate curved structural members continuously formed with at least one of the leading edge portion and the trailing edge portion. In addition, the elongate curved structural members may be configured such that the intermediate portion remains substantially rigid under compressive forces during insertion of the implant between bone surfaces of a patient. Also, the elongate curved structural members may include an elongate curved structural member extending longitudinally from the leading edge portion to the trailing edge portion and having a substantially sinusoidal configuration.

An implant may include a housing having a peripheral frame including an inner edge defining a central opening in a central portion of the implant; and a blade located within the central opening and having a retracted position in the housing and an extended position where the blade extends outwardly. The blade may be configured to be moved in a direction between the retracted position and the extended position. In addition, the blade may have at least one flange extending in a posterior direction. Also, the inner edge of the peripheral frame may include a posterior edge configured to support two portions of the blade in two respective locations, including a first location in which the posterior edge of the peripheral frame supports a first portion of the blade and a second location in which the posterior edge supports a second portion of the blade.
