Abstract

An intervertebral prosthesis (1 ), particularly for percutaneous mini- invasive surgery procedures, having the particularity that it comprises a plurality of mutually articulated segments (21-28). More precisely, the segments (21-28) are movable from an active configuration, in which they are arranged with respect to each other so as to form a disk-like body (2), to an insertion/extraction configuration, in which the segments (21-28) are substantially mutually aligned, and vice versa.
