Semirigid linking piece for stabilizing the spine

摘要

The invention relates to a connecting member for maintaining the spacing between at least two anchor members screwed into vertebrae. The connecting member comprises: a flexible part (10) divided into two branches (12, 14), the ends of said branches being interconnected in pairs and defining a first median plane (Pm), and two rigid rod-forming parts (20, 22) each having a fixing first portion (20′, 22′) and a second portion (20″, 22″), each of said second portions (20″, 22″) of said two rigid parts (20, 22) extending respective ends of said branches interconnected in pairs in opposite directions, so that said connecting member, whose fixing portions (20′, 22′) are fixed to respective anchor members, is able to bend elastically in a direction perpendicular to said median plane (Pm).
