A bone implant includes (a) a first layer provided over a first outer surface of the bone implant and being formed of a first material which is one of water-soluble and degradable in body fluids, the first layer having a first thickness and (b) a second layer provided over an outer periphery of the first layer and being formed of a biocompatible material, the second layer having a second thickness smaller than the first thickness.

Biodegradable orthopedic implants and coatings for the implants are provided. The implant can include a Mg alloy and a coating, where the coating includes silk fibroin. The coating can be anticorrosive and can include a first layer comprising polydopamine and a second layer comprising silk fibroin. The silk fibroin can be combined with cellulose nanocrystals. Methods for making coated orthopedic implants are also provided.

The present invention relates to a removable implantable device intended for the production of articular cartilage, comprising: a first support portion (2) made of biocompatible material, a second support portion (3) made of biocompatible material and movably mounted on the first support portion (2), the first support portion (2) and the second support portion (3) defining therebetween a cavity that forms a cell-growth space provided for receiving osteochondrogenic cells which multiply in the cell-growth space, and operable external mobilisation means (5A, 5B) which can be configured to move the second support portion (3) relative to the first support portion (2) so as to generate shear inside the cell-growth space.

The invention relates to a device for producing a knee spacer component by curing bone cement paste. The invention also relates to methods for producing knee spacer components using such a device.

A medical implant apparatus for total elbow arthroplasty is provided. The apparatus includes: a first rod member comprising a first nut, an eye hook, a first end, and a second end, wherein the first nut is disposed at the first end and the eye hook is disposed at the second end; a second rod member rotatably coupled to the first rod member, the second rod member comprising a first linear portion, a second linear portion, and an arcuate portion disposed between the first linear portion and the second linear portion, the arcuate portion being configured to form a predetermined angle between the first rod member and the second rod member; a positioning nut coupled to the first linear portion of the second rod member; and an aperture disposed in the eye hook.

A cement mold assembly configured to form a temporary implant for use in delivering antibiotics to an infected site can includes a first mold and a second mold. The first mold can have an open end and an inner wall. The first mold can define a tibial component forming cavity including a platform forming cavity and a stem forming cavity. The second mold can have a body portion configured to be slidably and progressively receivable by the inner wall into the tibial component forming cavity in a direction toward the closed end. Progressive advancement of the second mold into the tibial component forming cavity urges cement within the tibial component forming cavity against the body portion and the inner wall to form a unitary tibial component having a tibial tray portion formed by the platform forming cavity and a stem portion formed by the stem forming cavity.

A placeholder for vertebrae or vertebral discs includes a tubular body, which along its jacket surface has a plurality of breakthroughs or openings for over-growth with adjacent tissue. The placeholder includes at least a second tubular body provided with a plurality of breakthroughs and openings at least partially inside the first tubular body. The first and second tubular bodies can have different cross-sectional shapes, can be are arranged inside one another by press fit or force fit or can be connected to each other via connecting pins and arranged side by side to one another in the first body.

Spacer device for the two-phase treatment of infections of anatomic and reverse shoulder prostheses, including a humeral component equipped with a stem, a head component and means for connecting or articulating the humeral component with the head component.

The modular mould (1) for forming an orthopaedic spacer made of medical cement defines a moulding cavity (2) delimited by a moulding surface (3) configured for impressing a predetermined shape on the medical cement and realising the orthopaedic spacer.

The mould (1) comprises a first sector (7a), defining at least a first portion (8) of the surface (3), and a second sector (7b) defining at least a second portion (12) of the surface (3).

The mould (1) comprises at least a first forming insert (14) insertable in a housing (13) fashioned in at least one of said sectors (7a, 7b) and comprises a respective portion (8, 12) of the surface (3), said respective portion (8, 12) of the surface (3) having an elongate shape which is configured for forming an elongate portion of said orthopaedic spacer.

A trial liner system for use in hip arthroplasty. The liner system includes a first trial liner having a generally convex outer surface and a generally concave inner surface, the generally concave inner surface having a first locking mechanism. The liner also includes a second trial liner having a generally convex outer surface and a generally concave inner surface The generally convex outer surface includes a second locking mechanism adapted to lock with the first locking mechanism of the first trial liner when the second trial liner is inserted into the first trial liner.
