An implantable composition, method of making and using the implantable composition is provided. The implantable composition comprising a first set of fibers and a second set of fibers, the first set of fibers manufactured to have a first binding surface, the second set of fibers manufactured to have a second binding surface, the first binding surface of the first set of fibers configured to bind at least at or near the second binding surface of the second set of fibers and the second set of fibers configured to bind at least at or near the first binding surface of the first set of fibers.

A method for forming a thermoplastic body having regions with varied material composition and/or porosity. Powder blends comprising a thermoplastic polymer, a sacrificial porogen and an inorganic reinforcement or filler are molded to form complementary parts with closely toleranced mating surfaces. The parts are formed discretely, assembled and compression molded to provide a unitary article that is free from discernible boundaries between the assembled parts. Each part in the assembly has differences in composition and/or porosity, and the assembly has accurate physical features throughout the sections of the formed article, without distortion and nonuniformities caused by variable compaction and densification rates in methods that involve compression molding powder blends in a single step.

A bone fusion method, apparatus and device for insertion between bones that are to be fused together and/or in place of one or more of the bones, such as, for example, the vertebrae of a spinal column. The bone fusion device comprises one or more extendable plates having a central rib. The bone fusion device includes one or more support channels configured to receive an insertion instrument that is then secured to the bone fusion device via a coupling mechanism. As a result, the coupled device is able to be securely positioned between vertebrae using the insertion instrument with minimal risk of slippage.

A staged expansion of an intervertebral scaffolding system is provided, and also include a laterovertically-expanding frame operable for a reversible collapse from an expanded state into a collapsed state. The expanded state, for example, can be configured to have an open graft distribution window that at least substantially closes upon the reversible collapse.

A composite joint implant device replaces or repairs damaged meniscus tissue in an animal or human. In one embodiment, a composite joint implant comprises a polymeric body which is reinforced with a pre-formed engineered ligature mechanism. The ligature reinforces the polymeric body around the circumference and is used for attaching the device within an animal or human body. The ligature mechanism internally supports the transmission of vertical loads into tensile stresses. The ligature mechanism can be coated with a compatible material to promote integration with the polymeric body and coated with an encapsulation material.

Provided herein are compositions and methods for treating bone fractures. In particular, provided herein are systems comprising carbon fiber sleeves and biocompatible polymers and the use of such systems in treating or preventing bone fractures.

Some embodiments of the invention provide an apparatus that (1) delivers a fusion member between two vertebral bodies after at least a portion of the fibrocartilaginous disc between the vertebral bodies has been removed, and (2) affixes the fusion member to the vertebral bodies. In some embodiments, the apparatus includes (1) a fusion member that is delivered and positioned between the vertebral bodies, (2) a delivery mechanism that delivers and positions the fusion member between the vertebral bodies, and (3) an anchoring member that affixes the fusion member to the vertebral bodies.

Systems, devices, and methods are provided for orthopedic implants. The implants may include a base member, such as an acetabular shell or an augment, that is configured to couple with an augment, flange cup, mounting member, or any other suitable orthopedic attachment. Mounting members include, for example, flanges, blades, hooks, and plates. In some embodiments, the orthopedic attachments may be adjustably positionable about the base member or other attachments, thereby providing modularity for assembling and implanting the device, and various securing and/or locking mechanisms may be used between the components of the implant.

The fusion device for fusing a synovial joint of a human or animal patient, in particular a human facet joint, finger joint or toe joint, includes two pin-shaped anchorage portions and arranged therebetween a stabilization portion. The anchorage portions include a thermoplastic material which is liquefiable by mechanical vibration. The stabilization portion preferably has a surface which is equipped for enhancing osseointegration. The anchorage portions have a greater thickness and a greater depth than the stabilization portion. Then the fusion device is pushed between the articular surfaces and mechanical vibration, in particular ultrasonic vibration, is applied to the proximal face of the fusion device. Thereby the liquefiable material is liquefied where in contact with the bone tissue and penetrates into the bone tissue, where after re-solidification it constitutes a positive fit connection between the fusion device and the bone tissue.
