Title: INTERVERTEBRAL IMPLANT
Abstract:
The invention relates to an intervertebral implant (1), comprising an upper part (2) that has a support surface (5) for a vertebral body, and a lower part (3) that has a support surface (13) for an adjacent vertebral body. Contact elements (20, 21, 22, 23) are positioned on said upper part and said lower part and can be accessed from one side of the implant respectively, with an handling instrument. The aim of the invention is to minimize the structural height of the intervertebral implant (1) for insertion into an intervertebral space. To this end, the upper part (2) and the lower part (3) each have projections or recessed sections (9, 10, 16, 17, 19) which are oriented towards the other part and are laterally offset from each other in such a way that they engage in each other as the upper part (2) approaches the lower part (3). The contact elements (20, 21, 22, 23) are arranged on the upper part (2) and on the lower part (3) in projections (10, 16, 17) of these parts respectively, and the contact elements (20, 21, 22, 23) of the upper part (2) and the lower part (3) lie adjacent to one another and at least partially overlap in the direction of the height of the intervertebral implant (1).
