Abstract:
Angular orientation ring for an osteosynthesis device, for a spine, of a type comprising an essentially spherical outer face and an essentially cylindrical inner face intended to take a rod (21) of the device, wherein the ring has two mating parts (10), each part being substantially U-shaped with a bottom (11) and at least one pair of branches (12a, 12b) occupying a fraction of an axial dimension of said bottom, a distance (L) between the said pair of branches being close to the diameter of said rod intended to take the ring, and the two parts being designed to be inserted over the rod in a transverse direction in such a way that their respective bottoms substantially face each other across said enclosed rod, and such that their pairs of branches are side by side, said two parts jointly defining said essentially spherical outer face and said essentially cylindrical inner face.
