A medical implant (1) designed to enable bony fusion between a first bone (20) and a second bone (21), said implant being in the form of an elongate part comprising, extending along the longitudinal axis of the part, a head (2) and a body (3) spaced apart from each other by a connection zone (4) connecting the head (2) to the body (3), said head (2) being suitable for being inserted into the first bone (20), said body (3) being suitable for being inserted into the second bone (21), said body (3) being a hollow body that is slotted longitudinally along at least a portion of its length in order to define at least three elastically deformable longitudinal tabs (5) by means of which said body (3) is suitable for being inserted into the second bone (21).

Each longitudinal tab (5) of the body (3) is an arcuate tab (5) that presents an outer face (6), i.e. directed towards the outside of the body (3), extending longitudinally in curved manner with curvature having its concave side directed towards the outside of the body (3).

The present invention relates to a device and system for surgical fixation of small bones, small bone fragments, and osteotomies and more particularly to compression screw having an elongated and spiked tapered threaded leading portion which is joined to a section that is free from threads and a threaded trailing portion and more sharply tapered head which has threads that continue from the threads of the leading portion.

Disclosed is an assembly for foot arthroplasty, comprising a plurality of successively larger implants (10, 20, 30, 40) and a single drill (60); each implant includes, relative to a central portion (11), a proximal pin (12, 22, 32, 42) and a distal pin (13, 23, 33, 43) that is shorter than the proximal pin, said pins and said drill being tapered by 2 to 6.

Implants, devices, systems and methods for maintaining, correcting and/or fusing joint deformities are disclosed. The implant including a first member, a second member, and a coupling member with a first end and a second end, wherein the first end engages the first member and the second end engages the second member. Methods of using the implants for maintaining, correcting and/or fusing joint deformities are also disclosed.

Disclosed is a medical device having a first implant portion having a proximal end, a second implant portion connected to the first implant portion, the second implant portion having a distal end, and a driver assembly removably connected to the distal end, the driver assembly comprising a drill connected to the distal end at a connection.

The various embodiments of the present invention provide a system, including methods, apparatus and kits for connecting bones and/or bone portions using a multi-part bone connector with one or more rotating joints.

The invention concerns an arthrodesis implant (1) for promoting the osseous fusion of a first bone (2) with a second bone (3), said implant (1) comprising a primary component (4) including a primary anchoring body (5) and a male connector (6), and a secondary component (7) including a secondary anchoring body (8) and a female connector (9), said female connector (9) comprising: a main body (10) which extends longitudinally between a rear end (11) linked to said secondary anchoring body (8) and an opposite front face (12), and which has a lateral wall (14) linking said rear end (11) to said front face (12), a housing (15) formed within said main body (10) and configured to receive said male connector (6) in order to link together said primary (4) and secondary (7) components,
said female connector (9) further comprising an opening (18) which is formed in said main body (10), in communication with said housing (15), and which extends continuously on both said front face (12) and said lateral wall (14), and which is sized and configured to enable a lateral introduction of the male connector (6) into said housing (15) via said opening (18), each of said primary (4) and secondary (6) components forming an integral part made in one piece, and said primary (5) and secondary (8) anchoring bodies being respectively designed to ensure the insertion and anchoring of the primary component (4) into the first bone (2), and of the secondary component (7) into the second bone (3), by impaction or by forced wedging.

Osteosynthesis surgical implants.

An implant includes a body including a substrate and a bone interfacing lattice disposed on the substrate. The bone interfacing lattice includes at least two layers of elongate curved structural members. In addition, the at least two layers of elongate curved structural members include a first layer adjacent the substrate and a second layer adjacent the first layer. Also, the first layer has a first deformability and the second layer has a second deformability, wherein the second deformability is greater than the first deformability.

A surgical implant which includes: a first anchoring portion comprising two first arms movable between an inserting position and an anchoring position, in which the first arms are spread apart so as to be anchored in a first bone; a second anchoring portion to be anchored in the second bone; and an intermediate portion connecting the first anchoring portion to the second anchoring portion. The intermediate portion comprises: a recess; and a first connecting portion and a second connecting portion that are remote from one another. Bringing the first connecting portion and second connecting portion closer together moves the first arms from the inserting position thereof to the anchoring position thereof.

An interphalangeal prosthesis (10) includes a mobile element (12), a proximal fixation element (22), and a distal fixation element (24). The mobile element (12) includes a proximal portion (42, 62, 94) and a distal portion (43, 64, 92), and the proximal portion includes three proximal mobile coupling contiguous surfaces (46, 48, 50) and a proximal mobile coupling protrusion (52), and the distal portion includes a distal coupling mobile surface (54) and a distal mobile coupling protrusion (56), and the proximal portion and the distal portion move relative to each other primarily in an axis of rotation perpendicular to a plane that extends through the proximal mobile coupling protrusion, the three proximal mobile coupling contiguous surfaces, the distal coupling mobile surface, and the distal mobile coupling protrusion in an implanted configuration. The proximal fixation element (22) couples to the three proximal mobile coupling contiguous surfaces and the proximal mobile coupling protrusion of proximal portion, and couples to a joint bone surface and a bone canal. The distal fixation element (24) couples to the distal coupling mobile surface and the distal mobile coupling protrusion, and couples to an opposing joint bone surface and a second bone canal.
