A methodology for grafting together adjacent bony structures is provided using an implant device having an endplate with an inner disc portion and outer ring portion spaced from the inner disc portion by a connecting wall disposed therebetween. An endplate interior surface includes a retaining structure for securing the endplate to one of the bony structures, and endplate an exterior surface has an integrally formed socket. A ball-joint rod has a longitudinally extending body and an end, and at least a portion of the ball-joint rod end is curvilinear in shape. The curvilinear ball-joint rod end is rotatably disposed in the endplate socket to fixedly interconnect the bony structures.

An artificial functional spinal unit including an expandable intervertebral implant that can be inserted via a posterior surgical approach and used with one or more facet replacement devices to provide an anatomically correct range of motion is described. Lordotic and non-lordotic expandable, articulating implants and cages are described, along with embodiments of facet replacement devices and instruments for insertion. Methods of insertion are also described.

Method and set of surgical instruments for fitting a shoulder prosthesis, and the shoulder prosthesis. The proposed method seeks to interpose a bone graft between the previously prepared glenoid surface (G) of a scapula (S) of a patient's shoulder and the face of a glenoid prosthetic component opposite the articular surface. The set of instruments permit the bone graft to be taken from the upper epiphysis of the humerus (H), either in situ or ex vivo.

A non-biodegradable implant for the replacement and regeneration of biological tissue in the shape of a plug, comprising a base section (2) configured for anchoring in bone tissue, a middle section (3) configured for replacing cartilage tissue of an intermediate and deep zone of the cartilage layer and having a thickness of at least 0.2 mm, and a top section (4) configured for growing cartilage tissue onto and into, thus regenerating a superficial zone of the cartilage layer, wherein the middle and top section comprise the same thermoplastic elastomeric material, which is porous in the top section, and non-porous in the middle section, wherein the thermoplastic elastomeric material comprises a linear block copolymer comprising urethane and urea groups, and is substantially free of an added peptide compound having cartilage regenerative properties, and wherein the base section material comprises one of a biocompatible metal, such as titanium or titanium alloy, ceramic, such as sintered crystalline hydroxylapatite, mineral, such as phosphate mineral, and polymer, optionally a hydrogel polymer, and combinations thereof.

An endplate interior surface includes a retaining structure for securing the endplate to one of the bony structures, and endplate an exterior surface has an integrally formed socket. A ball-joint rod has a longitudinally extending body and an end, and at least a portion of the ball-joint rod end is curvilinear in shape. The curvilinear ball-joint rod end is rotatably disposed in the endplate socket to fixedly interconnect the bony structures.

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.

A composite material for use, for example, as an orthopedic implant, that includes a porous reinforced composite scaffold that includes a polymer, reinforcement particles distributed throughout the polymer, and a substantially continuously interconnected plurality of pores that are distributed throughout the polymer, each of the pores in the plurality of pores defined by voids interconnected by struts, each pore void having a size within a range from about 10 to 500 μm. The porous reinforced composite scaffold has a scaffold volume that includes a material volume defined by the polymer and the reinforcement particles, and a pore volume defined by the plurality of pores. The reinforcement particles are both embedded within the polymer and exposed on the struts within the pore voids. The polymer may be a polyaryletherketone polymer and the reinforcement particles may be anisometric calcium phosphate particles.

A system for replacing a portion of an articular surface including providing an implant site and installing an implant into the implant site. The implant site includes a first and a second excision site which at least partially intersect with one another. Each of the first and second excision sites are formed by providing a respective axis and excising a portion of the articular surface relative to the respective axes.
