<p>Flexible, sliding, dynamic implant system, for selective stabilization and correction of the vertebral column deformities and instabilities is constituted of a set is constituted by a set of flexible vertebral implants, which are articulated, sliding and dynamic (1) that belongs to the prosthetic and implants medicine field, constituted of two linear parallel sequences of U-shaped supports or platforms (3) where each pair of the sequence is connected with selective mobility to pedicular screws (4) fixed, also in parity, in the due posterior bony portion (5) of each vertebra (6) two thin, continue and flexible metallic blades (8) are coupled between the edges (lateral portion of the platforms with tracks (7) which belong to each U-shaped support. The inferior thin blade (8) is a fixed to the first U-shaped support (3) which corresponds to the first inferior vertebra (6) of the vertebral portion to be implanted. The flexible thin blade (8) is, on its turn, fixed on the upper vertebra platform in a way that it is blocked in only one extremity, thus with the free internal extremity causing the blades to slide in postural flex condition or any other movement requested to the extension of the implanted vertebral column (2).</p> |
