An intersomatic implant to be inserted into the intervertebral space is defined by two adjacent vertebrae, comprising a body having an upper face and a lower face, parallel to each other. The peripheries of the faces are connected by a vertical peripheral wall. Each of the faces has substantially the shape of a triangle with rounded angles, and each face includes three bearing surfaces located at the three rounded angles of the triangle. At least one of the upper and lower faces is provided with guiding means for the insertion of the implant into the intervertebral space. The guiding means comprises a plurality of ridges directed along an arc of circle, the center of which would be located in the anterior region external to the implant.

Intersomatic implant

An osteosynthesis clip having an overall U-shape, comprising two anchor bars and a connecting bar. The connecting bar including a longitudinal opening adapted to assume a closed configuration and an open configuration. The clip comprises a compression piece having a broadly oval-shaped section, housed in the opening. The piece is adapted to be rotated within the opening, thus causing the opening to shift from its closed configuration to at least one the open configuration and vice versa.

Osteosynthesis clip

The invention relates to an implant () for osseous fusion between two bones, including a first portion () having a longitudinal axis A, for being inserted in the first bone and including a first means () for attaching said implant in said first bone, and a second portion () having a longitudinal axis B, for being inserted in the second bone and including a second means () for attaching said implant in said second bone, said first and second portions () being connected by a central core (), said central core being a solid body, the cross-section of which, in a plane perpendicular to said longitudinal axis A, has the shape of a star having at least three points (), said first portion having three tabs (), each tab extending along said longitudinal axis A from the free end () of one of the points of said central core.

Arthrodesis implant

The invention concerns a bone fixing device () for immobilizing a linking rod () designed to connect at least one bone fragment () to another, said device comprising: at least one anchoring means () designed to be fixed on or in said bone fragment (); at least one receiving part (), secured to said anchoring means (), designed to receive at least part of said linking rod (); locking means () designed to lock said part of the linking rod () within said receiving part (). The invention is characterized in that said locking means comprise at least one solid element () having a longitudinal axis, said solid element including at least one inclined surface () capable, under the action of a thrust directed along the longitudinal axis of said solid element, of gradually wedging by friction said part of the linking rod () into said receiving part (), until said part of the linking rod () is completely locked inside said receiving part (). The invention also concerns an assembly comprising such a device and a linking rod.

Bone fixing device

The invention relates to a system which is used to replace ball bone joints. The inventive system consists of: a bone anchoring shell () comprising a smooth articular surface () on the inner concave face thereof; a prosthesis () comprising a polished ball () and a neck () which is characterised in that it is smooth and slightly flared, in order to enable a wear-free low friction movement; and a mobile articular cup () which slides (i) on the ball () and the neck () of a prosthesis () and (ii) in the smooth cavity () of the bone anchoring shell () and which is characterised in that the opening () in said cup () tapers towards the center thereof, with an inside diameter () of equal to or less than that of the ball (), such that the flared part adapts perfectly to the flared neck () in all of the respective positions of the mobile parts.

Ball-type triple-joint implant system for upper or lower limbs

A prosthesis for the knee articulation is provided which has a femoral implant having two condyles which are of convex shape, each having a variable radius, and a tibial implant having two cavities, each of which interacts with a respective one of the condyles. In its posterior region, the internal condyle has a spherical prominence which projects from the contact plane of the internal condyle and is intended to interact with a spherical cap hollowed into the posterior region of the internal cavity of the tibial implant.
