  • Publication number: 20220054272
    Abstract: Provided is an implant for restoring the mobility of an articular end of a bone. The implant includes a framework having a first face and a second face opposite the first face, the framework is defined by a plurality of free volumes formed by a grating, where the grating includes a first series of bars extending through the framework from the first face to the second face, and a second series of bars extending through the framework from the first face to the second face, wherein the second series of bars are parallel to one another, and spaced apart in pairs, where the bars have ends along the second face that are bevelled.

  • Patent number: 11197762
    Abstract: The aim of the invention is to restore the mobility of an articular end (2) of a bone (3) of a patient by means of a reconstruction implant. This implant (1), which permits reconstruction both of bone and of cartilage, comprises a grated framework (10) and a sheet (20) made of a biological tissue material, this sheet firmly covering one face (11) of the framework, while the opposite face (12) is designed to be pressed rigidly against, and firmly joined to, the end of the bone.

  • Patent number: 11160661
    Abstract: This shoulder prosthesis glenoid component (2) has on one of its faces an articulation surface (SA) adapted to cooperate with a humeral head and having, on an opposite face (SG) adapted to be immobilized on the glenoid cavity (G) of a shoulder, a keel (4) for anchoring it in the glenoid cavity (G). This keel (4) comprises a body (5) that extends from the opposite face (SG). The keel (4) comprises at least one fin (6) projecting from the body (5) 2 which runs over at least a part of the perimeter of the body (5).

  • Publication number: 20200281609
    Abstract: A steerable system and methods for accessing bone. A control mechanism includes a handle configured to be detachably secured to a trocar. The handle includes a drive shaft coupled to a sliding shaft such that relative rotation is prevented and relative translation is permitted. A rod having a preformed bend is removably disposed within the cannula. The rod is prevented from rotating relative to the drive shaft such that a deflection plane of the preformed bend is predefined relative to each of the sliding shaft, the handle, and the trocar when the handle is coupled to the trocar. Rotating a sliding ring of the handle translates the drive shaft to advance the rod beyond the trocar such that the preformed bend extends laterally out of the trocar in the deflection plane. The rod may be removed from the cannula, and material may be injected through the cannula.

  • Publication number: 20200187992
    Abstract: Methods of deploying an intravertebral implant having an expandable anterior part, a posterior part coupled to the expandable anterior part, and a pedicle fixation element. The expandable anterior part is positioned within the vertebral body, and the posterior part may be positioned within the vertebral body. The pedicle fixation element is anchored to the vertebral body. The expandable anterior part is moved relative to the pedicle fixation element, for example, in two degrees of freedom. Movement in a first of the two degrees of freedom is independent from movement in a second of the two degrees of freedom. The expandable anterior part may be translated without being rotated along a main axis of the pedicle fixation element. Filling material may be injected through the posterior part. Rotational movements of the expandable anterior part relative to the pedicle fixation element may be locked.

  • Patent number: 10603080
    Abstract: The present invention relates to an expansible intravertebral implant system comprising an intravertebral implant (1) with an expandable anterior part (11), which is expansible in a vertebral body, and a posterior part; and a pedicle fixation (2) having at least one hollow portion for receiving the posterior part. The present invention also relates to said expansible intravertebral implant system additionally comprising a posterior element (3), arranged partially outside the vertebra and rigidly connected to the pedicle fixation (2), for serving as an anchoring point for at least one intravertebral rod or at least one system of artificial ligaments.

  • Patent number: 10405890
    Abstract: The present invention relates to a bone fixation device (1) for securing attachment between a screw and a vertebra comprising two pedicles, comprising a hollow cavity having a longitudinal axis, a distal part (2) having itself a distal end and (7) a proximal end (8), a proximal part (3) having itself a distal end (9) and a proximal end (10) and a flange at the proximal end (10), characterized in that: —the distal part (2) comprises a deformable area (2D) comprising at least three helical slots (6); and—the distal part (2) comprises a full portion (5) located distally after said at least three helical slots (6); further characterized in that said full portion (5) cooperates with the screw such that once the screw abuts against the flange (4) of the bone fixation device (1), further screwing causes the deformation of the deformable area (2D) of the distal part (2) and the retraction of the distal end of the distal part (7) towards the proximal end of the distal part (8); and in that after screwing, the borders
