Abstract
A device for anchoring rachidian instrumentation on a vertebra, comprising at least one support, a carrier for coupling the instrumentation to the support and a structure for anchoring the support with respect to the vertebra, the support having a convex face shaped to conform to and lie against at least one portion of the concave surface of the posterior arch of the vertebra on one side of the spinous process of the vertebral column, and the anchoring structure rigidly linking at least two distinct parts of the support to at least two correspondingly distinct portions of the vertebra.
Claims14
A device for anchoring spinal instrumentation onto a vertebra, comprising:
- at least one support plate having coupling means for coupling the instrumentation to said support plate, said support plate having a convex face shaped so as to conform to and bear against the concave surface of the vertebral posterior arch,
- anchoring means for anchoring said support plate with respect to the vertebra, and wherein
- a) the convex face of said at least one support plate extends facing at least one process or at least one sacral hole of the vertebra,
- b) said anchoring means comprising means for anchoring at least two distinct portions of said support plate onto at least two corresponding distinct parts of the vertebra selected from (i) the spincos process of the vertebra, (ii) a transverse process of the vertebra, (iii) a pedicle of the vertebra, and (iv) a sacral hole of the vertebra,
- c) said anchoring means further comprising means for anchoring said support plate onto at least one process or sacral hole of the vertebra,
- d) said anchoring means also comprising a claw, an encircling arrangement, or a flange surrounding said process for clamping onto said process.
