<p>Prosthesis holder (1) made of a radiolucent material for a disc prosthesis (2) constituted by at least two parts which are mobile in relation to each another, including, on one side an element (9) for coupling to a sleeve and on the other side, an element for reversible coupling to a disc prosthesis, the reversible coupling element is arranged in order to allow decoupling, by simple traction exerted perpendicularly to a spinal column when the disc prosthesis has been correctly impacted between two vertebrae and the retention force of the reversible coupling element on the disc prosthesis is adjusted so as not to allow decoupling by simple traction when the disc prosthesis has not been correctly impacted, and an assembly including a prosthesis holder and a disc prosthesis.</p> |
