This disclosure relates to orthopaedic implant systems and methods for restoring functionality to a joint. The implant systems disclosed herein include offset arrangements that may facilitate conversion of the implant system during a subsequent surgical procedure.

A modular synthetic tissue-graft scaffold (10) includes one or more nominally identical scaffold cages (12) configured to facilitate regrowth of tissue of an organism in and around the scaffold cages. Each scaffold cage comprises a volumetric enclosure (18) bounded by a perforated wall structure (40). A recess (24) formed at one end of the volumetric enclosure defines an inner stepped coupling surface. An annular raised portion (26) positioned at the other end of the volumetric enclosure forms an outwardly projecting stepped seating surface sized to form a complementary matable surface to the inner stepped coupling surface for whenever an inner stepped coupling surface of another one of the cages is placed on the outer stepped seating surface of the scaffold cage. Corridors (46) extending through the perforated wall structure and communicating with passageways (54) within the volumetric enclosure enable migration of material within and out of the scaffold cage.

An implant couples a first bone of a hand to a second bone of the hand. The implant includes a body that defines a median plane. The body also defines a first joint surface having a first central region that articulates with the first bone. The body further defines a second joint surface having a second central region that articulates with the second bone, and the second central region is disposed on an opposite side of the median plane of the body relative to the first central region. The first and second central regions correspond to profiles of first and second axial segments, respectively, the first and second axial segments are each one of a cylinder, a cone and a torus and are centered on first and second axes, respectively, and the first and second axes, as projected on the median plane, are substantially perpendicular to each other.

Compositions comprising a cartilage sheet comprising a plurality of interconnected cartilage tiles and a biocompatible carrier are provided. Methods of manufacturing cartilage compositions comprising a cartilage sheet comprising a plurality of interconnected cartilage tiles 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.

A medical product, preferably for use in treating, in particular filling and/or closing a bone cavity, wherein the product comprises a plurality of interconnected members, wherein each member has a peripheral boundary and the boundaries of adjacent members engage with one another. And a method for producing a medical product, preferably for use in treating, in particular filling and/or closing a bone cavity, wherein the product comprises a plurality of interconnected members, wherein each member has a peripheral boundary and the boundaries of adjacent members engage with one another.

An interlocking reverse hip prosthesis including an acetabular cup having an opening in the central portion of the cup being implanted in the acetabular cavity. The opening has a circular extending wall protruding into the concave portion of the cup a distance at least equal to the diameter of the opening. The inward extension of the cup provides a female Morse taper suited for receiving the male Morse tapered post of the acetabular ball. After implantation of the acetabular cup, the surgeon can easily secure the cup to the acetabular bone using several screws without the interference of the central peg (as in prior implants). The femoral ball is then attached to the cup via central Morse taper.

A short-stem femoral implant suitable for use in hip arthroplasty configured to self-stabilise against sliding across the endo-cortex when implanted in a subject's femur. The femoral implant includes a distal end configured to engage in abutment with the lateral endo-cortex of the subject's femur at two distal locations such that when implanted, the femoral implant has a reduced tendency for sliding across the endo-cortex.

A medical implant which comprises a porous lattice is fabricated with additive manufacturing techniques such as direct metal laser sintering. A CAD model of the porous lattice is created by defining a trimming volume and merging some lattice elements with adjacent solid substrate.
