  • Patent number: 9918847
    Abstract: 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.

  • Patent number: 7955279
    Abstract: According to the invention, the patient (4) is placed upon a patient support (3) between an X-ray source (1) and a support for the target plate (2) sensitive to the X-rays. The patient support (3) is connected to a device for detecting the horizontal position of the global axis of gravity (5) of the patient when the X-ray source (1) is in operation. The patient (4) can, for example, remain standing. The inventive device can superimpose an image (Hg) of the global axis of gravity (5) on the digital radiographic image of the patient (4).

  • Patent number: 7572277
    Abstract: A connector (1) for a spinal osteosynthesis device, for connecting two rods to a plate fixed in a vertebra, includes a first orifice (2) opening onto two opposed faces (3, 4) of the connector (1), and two other orifices (5, 6) opening onto two other opposed faces (7, 8) of the connector (1). Each of the two other orifices (5, 6) are each designed to receive a rod (14, 15) of the osteosynthesis device. The connector (1) includes a mechanism making it possible, when the connector (1) is push-fitted onto a protrusion (100) of a bone anchor member, to tighten the rods (14, 15) simultaneously in the two other orifices (5, 6) when a nut (22) is screwed onto the protrusion (100). An assembly for spinal osteosynthesis device includes a plate (16) that includes a protrusion (100), a connector (1) as previously described, and a nut (22).

  • Patent number: 7361150
    Abstract: The invention concerns a method which consists in producing a radiographic image of the skeleton to be studied, determining the position of the body's global axis of gravity (5), selecting on the image segments of the skeleton (S1-S7) to be considered and their articulations (A5), locating the main tensor muscles (M1-M6, M62), and determining by calculation the intensity of the return forces exerted by said tensor muscles to compensate the gravitational force.

  • Patent number: 6248104
    Abstract: This instrumentation comprises at least one vertebral rod (1), bone anchoring elements (2) spaced along the rod, a connector (3) connecting the rod to each anchoring element, and pressure means (4) for clamping together the rod, the anchoring element and the connector; each anchoring element has a bearing surface (7) for the rod which is inclined relative to the longitudinal axis (XX) of the anchoring element; in the connector there is provided a cavity (11) providing at least one bearing point for the rod held trapped between said inclined bearing surface and a wall (12) of the cavity, and the latter is extended by a lateral aperture (18) permitting insertion of the vertebral rod radially in its cavity; this instrumentation is easy to use by the surgeon owing to the convenience of insertion of the rod in the connector, and the direct bearing of the rod against the surface (7) of the anchoring element (2) reduces its transverse overall size.

  • Patent number: 5810816
    Abstract: The stabilizing device can be adapted to an anchor such as a hook (1) of the usual shape, with a hook body (4) and an incurved lug (7). The device including a stabilizing staple fastener (3) having a body (21) and staple legs (22-25). Said fastener body (21) is adapted so that the securing member secure the hook (1) to an attachment rod (52) also attach the fastener (3) to the hook (1), by forcing back the legs (22-25) in the direction of the incurved lug (7) so as to pierce a portion of the vertebra located in the hollow of the hook (1). The hook (1) is thereby effectively stabilized on the vertebra.

  • Patent number: 5810817
    Abstract: An apparatus including vertebral anchoring elements, such as a bone screw (1) or a hook (2), with a threaded cylindrical portion (5) and a locking plate (7). A nut (8) may be screwed onto the threaded cylindrical portion (5) to tighten the tightening portion of a slide (4) on a rigid connecting rod (3) with a circular cross-section. The rod (3), the slide (4) and the anchoring element (1,2) may be sufficiently rigidly connected by means of non-slip projections on the engaged side of the locking plate (7), on the corresponding side of the slide (4), and on the surface thereof which surrounds the rod (3). The stiffness of the apparatus may thus be enhanced, so that improved support of the vertebrae and easier fitting and adjustment of the apparatus may be achieved.
