| 摘要 |
<p>The invention relates to a prosthesis of a cervical intervertebral for the intervertebral space of a cervical spine bound by the ending plates (12, 13) of adjacent vertebral bodies whose surfaces are provided with very mach bent external lateral areas (4) adjacent to a central area (2) substentially flat on the front plane thereof. Said external areas are more mineralised than the central area and consequently are particularly stable. At least one of the prosthesis surfaces, (10, 11) which are provided for to be based upon the vertebral body surface, has a lateral extension in the external areas (4). The convex curvature of the prosthesis surface (9, 11) at least is equal on the front plane thereof to the corresponding curvature of the ending plates (12, 13). The inventive prosthesis is also supported by said external particularly stable areas which do not require any significant removal of material.</p> |
