摘要： A partial endoprosthesis device (11) for preserving the motion of a vertebral joint for implant into a spinal segment (10) comprising an articular portion (13) being elongated along a longitudinal axis (14) with a first face (15) and a second face (17) opposite to the first face (15), the first face comprising a central protrusion (18) having a height (H), with respect to the face, and a surface (16) of an osteointegrable material. The protrusion is configured so that, by implanting the device (11) with the articular portion (13) inserted between an upper articular facet (3') of a lower vertebra (10') and a corresponding lower articular facet (3") of upper vertebra (10") adjacent to the lower vertebra, and with the first face (15) in contact with a first articular facet selected between the upper articular facet (3') and the lower articular facet (3"), and with the second face (17) in contact with a second articular facet respectively with the lower articular facet (3") and with the upper articular facet (3'), it is obtained that the articular portion (13), with the first face (15), pushes against the first articular facet and finally becomes integral by osteointegration with the lower articular facet (3") and, with the second face (17), slidingly engages with the lower articular facet (3').

摘要： A vertebral fusion device (40', 51, 51 ',52, 53) comprising a support element configured for insertion between two corresponding vertebral portions of two adjacent vertebrae (10,20), such as spinous processes (12,22) and transverse processes (14,24), or joint surfaces of the vertebral bodies (11,21) or of the facets (13,23), comprising a granular osteosynthesis material (32), preferably in cortico-spongeous chips made of bone bank human bone, which is plastically deformable, and a hollow container body (31, 31 ',41) that contains the osteosynthesis material (32) and has a side wall, for example made with a network of interlaced meshes, and two open end portions (35,45',45") to allow a contact between the osteosynthesis material (32) and respective surfaces of said corresponding vertebral portions, so that the osteosynthesis material (32) is kept in a compressed condition between said corresponding vertebral portions and receives mechanical loads therefrom which promote osteosynthesis. In particular, the side wall of the hollow container body (31,31', 41) is substantially radially inextensible. The fusion devices may form a vertebral fusion system comprising a plurality of devices selected among an intersomatic device (51,51'), an interspinous device (40'), an interarticular device (52), an intertrasverse device (53), in particular the system may comprise an interspinous device (40'), at least one intersomatic device (51,51 ') and a couple of interarticular devices (52) to obtain a primary stabilization of the implant and a successful osteosynthesis.

摘要： An intervertebral support device to impose an anatomic distance between two adjacent vertebral bodies (11a, lib), comprising a couple of vertebral support elements for introduction between the edge portions of the rear half of the vertebrae, at respective substantially symmetrical positions of the instantaneous rotation axis of the natural relative flexion - extension (50) movement of the two adjacent vertebrae. The device assists stabilizing and/or restoring the correct position of the rotation axis, which characterizes the first stage of the degenerative breakdown, without significantly limiting the relative movement of the two vertebrae. The support elements have preferably a constraint means that constrains them (100) to the edge portions of the vertebral bodies, in particular to resist the reaction force on the intervertebral disc. For instance, this constraint means consists of protruding parts (37) that protrude with respect to the support surfaces (32), for engaging with the inner surfaces (51 a, 51b) and/or the external surfaces (52a, 52b) of the edge portions (150) of the adjacent vertebral bodies (13a, 13b).
