Modular nucleus pulposus prosthesis |
摘要 |
A modular nucleus pulposus prosthesis having at least two hingedly connected tear drop shaped disc bodies which combined to form a discoid endoprosthetic disc. The complimentary segments are substantially identical including outer circumferential walls roughly equal to a semi-circle aligned along concave-convex inner wall inner walls forming a common “s” shaped border and are positioned to form a generally symmetrical discoid congruent structure which can be placed within the annulus of a spinal disc section. Disc segments may define structures to support, position and secure the segments to one another intradiscally. |

1. An endoprosthesis for insertion into the annulus of a spinal disc comprising:
a generally discoid assembly comprised of biocompatible materials having latitudinal and longitudinal axes, said discoid assembly formed by a plurality of complimentary hingedly connected tear-drop shaped bodies, each of said bodies having a curving pointed tip end and a blunt end opposite said pointed tip end mateably arranged along a common “s” shaped border in a congruent manner, said discoid assembly having upper and lower convex surfaces, said upper and lower convex surfaces having a curvature that generally corresponds with a pair of a human vertebral segments. |
