Abstract: A spinous process implant, and a method therefor can be positioned with its longitudinal axis substantially perpendicular to the median sagittal plane of the patient, between an upper and an adjacent lower spinous process. The implant comprises, as spacers, upper support means, and lower support means, which, in each case, are applied with a recess saddle against the upper or lower spinous process. The support means can be spread apart in each case by means of clamping means, which are arranged between the support means in the longitudinal direction.

Abstract: The invention concerns an intervertebral disc prosthesis (10) with a first prosthesis plate (20) and a second prosthesis plate (30), wherein the first prosthesis plate (20) has on its side (20b) facing the second prosthesis plate (30) a concave recess (22) in which engages a convex projection (32) arranged on the side (30b) of the second prosthesis plate (30) facing the first prosthesis plate (10), wherein the convex projection (32) and/or the concave recess has at least one elastic element (35).
