The present disclosure relates to a system, apparatus and method for near-simultaneous and integrated delivery of bone graft material during the placement of surgical cages or other medical implants in a patient's spine. The integrated fusion cage and graft delivery device according to various embodiments delivers and disperses biologic material through a fusion cage to a disc space and, without withdrawal from the surgical site, may selectively detach the fusion cage for deposit to the same disc space. The integrated fusion cage and graft delivery device is formed such that a hollow tube and plunger selectively and controllably place bone graft material and a fusion cage in or adjacent to the bone graft receiving area. The system also includes a cover plate that secures to the fusion cage.

Compositions and methods for making biocompatible articles are provided. A method includes preparing a 3D printable mixture and depositing successive layers of the mixture in a predetermined pattern to form a porous biocompatible article. The predetermined pattern has a porosity suitable for a bone or cartilage scaffold. Associated 3D printable compositions and porous articles made from the described methods are also described. The preparing a 3D printable mixture can comprise conjugating an alkyne-terminated polymer to a peptide to form a peptide-containing composite, or providing a mixture that comprises a ceramic material and a binder, and wherein the 3D printable mixture comprises from 50 wt. % to 80 wt. % of the ceramic material.

An ankle prosthesis is provided that includes a tibial stem with a retractable member configured to be controllably movable between a retracted position and an extended position so that in the extended position the retractable member engages the surface of the bone that defines an intramedullary canal so as to enhance anchoring of the tibial stem within the tibia.

Implants are provided. In one exemplary embodiment, an implant includes a spacer configured to be implanted within a joint. The spacer includes an elongated central body extending from a first end to a second end with a longitudinal axis extending therebetween, and first and second wings extending from the first and second ends of the elongated central body, respectively. The elongated central body has a first maximum height in a direction transverse to the longitudinal axis, and each of the first and second wings has a maximum height greater than the first maximum height. When implanted and in the inflated state, at least one of the first wing and the second wing is configured to mechanically interlock with a portion of the anatomy to thereby self-anchor the spacer to the joint and inhibit migration of the spacer. Implant systems and methods for biomechanically augmenting muscle function are also provided.

The invention features a glenoid (shoulder socket) implant prosthesis, a humeral implant prosthesis, devices for implanting glenoid and humeral implant prostheses, and less invasive methods of their use for the treatment of an injured or damaged shoulder.

The invention relates to an augmentation device comprising an annular cone surrounding a channel extending through the cone from a proximal cone end to a distal cone end of the cone. The invention further relates to an augmentation system comprising such an augmentation device and an applicator, as well as an implantation method of an augmentation device using such an augmentation system.

A system for converting a first joint prosthesis to a second joint prosthesis in-situ includes a plurality of inserts having a bone interface side and a component facing side and a plurality of articulating components having a cavity configured to receive at least one of the plurality of inserts. The plurality of inserts may be unicompartmental, bicompartmental, or tricompartmental. The inserts may be made of metal and may have a bone contacting surface made of a porous metal. The plurality of articulating components may be unicompartmental, bicompartmental, or tricompartmental. The articulating components may be sized and shaped to cover one or more of the plurality of bone interface components and span a distance therebetween. The articulating components may be made of a polymer.

The invention relates to a glenoid (shoulder socket) implant prosthesis, a humeral implant prosthesis, devices for implanting glenoid and humeral implant prostheses, and less invasive methods of their use for the treatment of an injured or damaged shoulder.

Intervertebral implants for implanting into an intervertebral space are provided. The implants can comprise one or more layers that are operably attached to one another. An implant can comprise a first layer having a first mating surface that mates with a second mating surface of a second layer. The first mating surface and the second mating surface can have features that allow them to complement each other. The implants can include one or more bore holes for receiving a fixation member. The bore holes can be horizontal, vertical or diagonal. In some cases, the bore holes will be blind bore holes.
