Abstract: A linking element for a spinal fixing system is designed to link at least two implantable connecting assemblies. The linking element is formed at least partly of a support made of polymeric material and of two rods with a first rod, bent or not, substantially coaxial with the support, and a second rod formed of turns surrounding the first rod with the turns being at least partly embedded in the support. A spinal fixing system has at least two implantable connecting assemblies linked by at least one linking element.

Abstract: A connection assembly for spinal osteosynthesis has a bone-anchor having a connection zone intended to cooperate with a connection device, in which the connection device has, in its lower part, a spherical shape in order to permit a free positioning of the connection device in connector. The connector has a cavity of complementary shape to the spherical shape. This spherical shape forms a limit of longitudinal positioning with the connector.

Abstract: The invention concerns in particular an invertebral prosthetic disc nucleus (1) in the form of a flexible filament (5) of a biocompatible elastomer. The filling material is adapted for injecting by means of a hollow needle (4) into the cavity (2) of the annulus. The filament winds when contacted with the walls (6) and with its own segments so as to form an entanglement filling the cavity.

Abstract: A surgical implant that supports and assists movement adjacent vertebrae including a top part and a bottom part associated with the spinous process of one of the vertebrae, each part including means for association with one process and reciprocal means or rotational association with the other part and forming a swivel joint.

Abstract: The invention concerns an instrument for moving a vertebra (1) relative to another (2) comprising: a stem (3) consisting of a substantially horizontal crosspicce (5) and a first arm (4) whereof the lower end (15) has means (24) to be anchored to a first vertebra (2); and a second arm (6) whereof the lower end (10) has means (25) for being anchored to a second vertebra (1), and one upper end has a means (7) for actuating in translation said second arm (6) along a direction substantially perpendicular to the crosspiece (5), said actuating means being associated with the crosspiece (5). The second arm (6) is deformable along at least one degree of freedom between the lower end (10) of the second arm (6) and its actuating means (7).
