Devices and methods for attaching a support to the sacrum. One device may include first and second anchors that mount to the sacrum, and first and second lateral extensions coupled to the anchors to secure the device to the sacrum. A bearing face having a width is positioned between the lateral extensions. The face may have a height in an anterior-posterior direction greater than the spinous process of the sacrum. Further, the bearing face may be oriented in a superior direction when the device is mounted to the sacrum. An implant may be supported by the device to space the sacrum and L5 vertebra. The implant may be an interspinous device and positioned between the L5 spinous process and the bearing face. The implant is supported at least in part by the bearing face.

Artificial spinous process for the sacrum and methods of use

An implant assembly for stabilizing a spinal motion segment includes a spacer which is at least partially flexible and positionable in an interspinous spacer between adjacent spinous processes. The spacer member includes upper and lower surfaces structured to receive a respective adjacent one of the upper and lower spinous processes of the spinal motion segment and a body having distinctive first and second sections with differing flexibility to modify the manner of movement at the spinal motion segment.

Vertebral osteosynthesis 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; 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.

Vertebral osteosynthesis equipment

This interspinous implant is able to be engaged between the spinal processes of two vertebrae and formed by a block of elastically deformable material. According to the invention, the block is subdivided into a central part made from a first elastically deformable material and two lateral parts made from a second elastically deformable material, more rigid than the first material. The lateral parts are situated on the two opposite lateral sides of the central part, that is to say on the sides intended to be situated longitudinally on each side of the spinal processes after implantation, and being connected to the central part.

Interspinous implant

An implant assembly for stabilizing a spinal motion segment includes a spacer which is at least partially flexible and positionable between adjacent spinous processes. The spacer member includes upper and lower surfaces structured to receive a respective adjacent one of the upper and lower spinous processes of the spinal motion segment and a body having flexibly distinctive first and second sections relative to one another configured to modify the manner of movement at the spinal motion segment.

A prosthetic device for insertion in a spinal column includes a first, second, and third members. The first member includes an inferiorly extending tab and is of a relatively flexible material. The second member includes a superiorly extending tab and is of a relatively flexible material. The third member defines a superior opening for receiving the inferiorly extending tab and an inferior opening for receiving the superiorly extending tab and is of a relatively stiff material. The device also includes a means for providing a rigid connection of the third member to a vertebra.

Intervertebral prosthetic device for spinal stabilization and method of implanting same

A prosthetic device and method of inserting same between adjacent vertebrae, according to which a first member of a relatively flexible material is adapted to extend between the vertebrae; and at least one second member of a relatively stiff material is supported by the first member.

Equipment includes bony anchoring members one or two linking rods, intended to be connected to the anchoring members, and parts for connecting the linking rod(s) to the anchoring members, at least one anchoring member including a proximal threaded stud and a clamping element for assembling a connecting part thereon, the connecting part including a clamping element for immobilizing the linking rod with respect thereto. The connecting part includes a rounded section for hugging a linking rod and two parallel branches having holes enabling engagement on the proximal threaded stud of the anchoring member; and the clamping elements may be engaged coaxially on the proximal threaded stud of the anchoring member, a first clamping element enabling the assembly of the connecting part on this proximal threaded stud and the second clamping element enabling to clamp both branches of this connecting part.

The invention concerns an assembly () comprising an interspinous wedge () configured to be inserted between the spinous processes () of two vertebrae () 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 () further comprises: two compressive lateral elements (), designed to be placed on either side of the wedge () in the longitudinal direction, said compressive lateral elements () being deformable between releasing positions, wherein they are relatively spaced apart from the wedge () in the transverse direction, and compressive positions, wherein they are relatively close to the wedge () in the transverse direction; and two lateral transmission elements (), placed between the compressive lateral elements () and the wedge (), configured to press against the wedge () in the transverse direction thereof, at the interspinous zone () of the wedge ().

Posterior vertebral support assembly

A method of implanting a spinal prosthesis comprises inserting a first member between superior and inferior spinous processes associated with respective superior and inferior vertebrae. The superior and inferior vertebrae are separated by an intermediate vertebra. The method further includes inserting a second member through a channel in the first member. After the second member is inserted, the method requires removing the second member from the channel and inserting a third member through the channel. The third member has a different stiffness than the second member. Finally, the method requires anchoring the third member to the intermediate vertebra, while the third member is inserted through the channel. The third member is anchored at first and second locations disposed on respective first and second lateral sides of the intermediate vertebra.

A vertebral osteosynthesis device includes at least two bone anchoring elements () in the vertebral bone structures respectively (S, L), a longitudinal linking member () between the bone anchoring elements, and connector links () between the bone anchoring elements and said linking members. Each bone anchoring element includes a bond fixing part (), a head () to be gripped by a screwing device, a threaded shaft () extending the grip head, and a clamping element () 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 () is provided at its end with a hinge ball joint () in a housing () of the grip head (), enabling a multidirectional adjustment of the shaft () and a positioning of the connector link () adapted to the vertebral segment configuration (S, L, . . . Lw) receiving the bone anchoring elements.

Multidirectional adaptable vertebral osteosyntsis device with reduced space requirement
