Abstract

A device for replacing all or part of the posterior vertebral articular processes (3, 13), engaging a support (7) and members for anchoring same to the vertebra, wherein each complete (5, 15) or partial (1, 11), upper (1, 5) and/or lower (11, 15) prosthesis mimics the anatomical shape of the posterior vertebral articular process and comprises artificial sliding surfaces (2, 12) facing one another between at least two adjacent vertebrae while adapting to the physiological orientation thereof, and the anchoring members comprise a support (7) with a convex surface matching and engaging at least one portion of the concave surface of the posterior arch of the vertebra on at least one side of the spinous process (9), and rigidly connect at least one separate portion of the support (7) to a corresponding separate portion of the vertebra.A device for replacing all or part of the posterior vertebral articular processes (3, 13), engaging a support (7) and members for anchoring same to the vertebra, where each complete (5, 15) or partial (1, 11), upper (1, 5) and / or lower (11, 15) prosthesis mimics the anatomical shape of the posterior vertebral articular process and understood artificial sliding surfaces (2, 12) facing one another between at least two adjacent vertebrae while adapting to the physiological orientation thereof, and the anchoring members understood a support (7) with a convex surface matching and engaging at least one portion of the concave surface of the posterior arch of the vertebra on at least one side of the spinous process (9), and rigidly connect at least one separate portion of the support (7) to a corresponding separate portion of the vertebra.
