摘要:
The invention concerns an assembly (1) comprising an interspinous wedge (5) configured to be inserted between the spinous processes (9) of two vertebrae (2) to be treated, whereof at least one zone designed to be placed between the spinous processes of the vertebrae is made of an elastically deformable material. The assembly (1) further comprises: two compressive lateral elements (6), designed to be placed on either side of the wedge (5) in the longitudinal direction, said compressive lateral elements (6) being deformable between releasing positions, wherein they are relatively spaced apart from the wedge (5) in the transverse direction, and compressive positions, wherein they are relatively close to the wedge (5) in the transverse direction; and two lateral transmission elements (7), placed between the compressive lateral elements (6) and the wedge (5), configured to press against the wedge (5) in the transverse direction thereof, at the interspinous zone (10) of the wedge (5).

This equipment includes: bony anchoring members, such as pedicular screws or hooks, at least one of which includes a proximal threaded stud for receiving a nut and a base portion for anchoring to a vertebra; one or two linking rods, intended to be connected to these anchoring members and attached to the vertebrae by these anchoring members, parts for connecting these linking rods to the anchoring members, and extension pieces for engaging on the proximal stud(s) of the anchoring member(s) for running down connecting parts on this or these proximal stud(s) until they rest on the proximal zone(s) of the base portion(s) of the anchoring members. The proximal stud of at least one anchoring member and the extension piece intended to be used with this anchoring member include positioning elements for positioning the extension piece on the free end of the proximal stud, concentrically thereto.

This device (10) includes an interspinous implant (1) having a flexible structure, capable of being inserted between the spinous processes (100) of two vertebrae, the areas (Z) of these respective spinous processes (100) bearing against the implant (1) defining a longitudinal axis (L) of the implant (1). According to the invention, the device includes at least one cerclage (15) capable of being adjustably engaged around the implant (1), at a centre section (4) of this implant (1), in a plane (P) perpendicular to said longitudinal axis (L); this cerclage (15) is made of a material that is inextensible in the circumferential direction of this cerclage (15), so that it makes it possible to restrain deformation of the implant (1) at the centre section (4), within the entire said plane (P), during exertion on this centre section (4) of opposing compressive forces exerted by the spinous processes of the vertebrae during a posterior movement of the spinal column.

The invention concerns an assembly comprising: a rear damping implant (10), configured to be laterally placed at the blade-spinal junction of two vertebrae (2, 3) treated without resection of the supra-spinal rear ligament (5), said implant (10) having a height such that, when set in place, it enables, to reset the supra-spinal rear ligament in anatomical tension; and at least a damping interbody implant (11), configured to be inserted between the vertebral end-plates of the two treated vertebrae (2, 3), by the same path used during dissectomy, said implant (11) having a height such that, when set in place, it enables to restore the anatomical height of the intervertebral disc (4) and to reset the front common ligament in anatomical tension.
摘要:
Equipment includes bony anchoring members, one or two linking rods, intended to be connected to these anchoring members, and parts for connecting the rod(s) to the anchoring members; at least one anchoring member includes a proximal stud articulated with respect to a base portion enabling bony anchoring; clamping elements enable assembly of the connecting part on the anchoring member. The proximal stud includes a surface forming an axial stop, against which the connecting part is intended to rest, and the clamping elements clamp this connecting part against this surface which is positioned so that the connecting part, when clamped there against, is not clamped against the base portion so that there remains, after clamping, a possibility of articulated backlash of the proximal stud with respect to the base portion.

This equipment includes bony anchoring members, such as pedicular screws (1) and/or hooks, one or two linking rods (2), intended to be connected to these anchoring members, and parts (3) for connecting this(these) linking rod(s) (2) to these anchoring members, at least one anchoring member including a proximal threaded stud (6) and a clamping means (4) for assembling a connecting part (3) thereon, and this connecting part (3) including a clamping means (5) for immobilising the linking rod (2) with respect thereto. According to the invention, said connecting part (3) comprises a rounded section (20) intended for hugging a linking rod (2) and two parallel branches (21, 22) drilled with holes enabling engagement on the proximal threaded stud (6) of said anchoring member (1), these two branches (21, 22) being laid out for being clamped in order to clamp said rounded section (20) around the linking rod (2); and said clamping means (4, 5) may be engaged coaxially on the proximal threaded stud (6) of said anchoring member (1), a first clamping means (4) enabling the assembly of the connecting part (3) on this proximal threaded stud (6) and the second clamping means (5) enabling to clamp both branches (21, 22) of this connecting part (3).
摘要:
An equipment includes at least a shoring rod and at least an anchoring assembly of the shoring rod to a vertebra; each anchoring assembly comprises a base integral with a hook which has substantially planar part, extending in a parallel plane, or forming a slight angle, less than 15 degrees, with the base. The base has a hole which runs right through it, having an oblong cross-section, and the anchoring assembly comprises a hook-shaped component whereof the part corresponding to the base of the hook is linked to a threaded rod capable of being engaged in the hole with the possibly of pivoting about an axis and of displacement in the plane, and capable of receiving a screw.

A vertebral osteosynthesis device includes at least two bone anchoring elements (1) in the vertebral bone structures respectively (S, L5.), a longitudinal linking member (2) between the bone anchoring elements, and connector links (3) between the bone anchoring elements and said linking members. Each bone anchoring element includes a bond fixing part (4), a head (5) to be gripped by a screwing device, a threaded shaft (7) extending the grip head, and a clamping element (8) to be screwed on said shaft to lock together the connector link, the longitudinal linking member and the corresponding bone anchoring element; the threaded shaft (7) is provided at its end with a hinge ball joint (11) in a housing (12) of the grip head (5), enabling a multidirectional adjustment of the shaft (7) and a positioning of the connector link (3) adapted to the vertebral segment configuration (S, L5, . . . Lw) receiving the bone anchoring elements.
