POLYAXIAL FASTENER ASSEMBLY

摘要

A polyaxial fastener assembly (10) including a mechanical fastener (12) having a proximal end (14) and a distal end (16), the proximal end including a contact stress element (18), an articulating element (22) disposed on the mechanical fastener adjacent and distal to the contact stress element, the articulating element having a convex surface and the contact stress element having a convex surface, and a receiver member (26) adapted to receive therein the mechanical fastener, the receiving member having a first aperture (28) having a concave bearing surface (30) that articulates with the convex surface (24) of the articulating element, a second aperture (32) adapted for receiving therein an auxiliary mechanical fastener (34), and a third aperture (36) for receiving therein a connector element (38), the third aperture being arranged with respect to the first and second apertures such that a connector element disposed in the third aperture is disposed between the contact stress element and the auxiliary mechanical fastener.
