KIT FOR CONSTRUCTING A SPINAL DISK PROSTHESIS, AND SYSTEM FOR CONSTRUCTING DIFFERENT SPINAL DISK PROSTHESES

摘要

The invention relates to a kit for constructing a spinal disk prosthesis provided for arrangement in a spinal disk compartment limited by vertebral bodies, comprising two prosthesis plates (10) which are disposed in a manner movable relative to each other, the exterior surfaces (12) of which are provided for contacting surfaces of vertebral bodies positioned on the opposite side, and the interior surfaces (14) of which form corresponding bearing surfaces of a pivot bearing (34; 134; 334; 434) after assembly. According to the invention, the kit further comprises a limiting device (24, 26; 150, 152; 254, 256; 364; 466), which is associated with the pivot bearing (34; 134; 334; 434), for limiting a pivot movement about a rotational axis (36) oriented substantially normally to the exterior surfaces (12) of the prosthesis plate (10). For this purpose, the limiting device may be connected to the prosthesis plates (10).
