摘要：
An intervertebral support device configured to be disposed between two adjacent vertebral bodies (13a, 13b) of the spine (11) of a patient, such that relative movement between said adjacent vertebral bodies (13a, 13b) and that said support device can contribute to supporting the load of an upper vertebral body (13a) on a lower vertebral body (13b), said vertebral bodies (13a, 13b) having a sagittal axis (18) and a middle sagittal plane (π ), said adjacent vertebral bodies (13a, 13b) having a respective front half (13'a, 13'b), a respective rear half (13 "a, 13" b) and respective edge portions (53a, 53b) facing each other each other, said device comprising a pair of support elements (30, 30 ', 40, 65', 65 ", 70, 70 '), each support element of said pair having a support surface (32), said being support elements configured to be inserted between said portions edge (53a, 53b) of said respective rear half (13 "a, 13" b) of said adjacent vertebral bodies, such that said support surface (32) is coupled with said edge portions (53a, 53b) and helps support said load, and said support elements (30, 30 ', 40, 65', 65 ", 70, 70 ') are configured to be placed on opposite sides of said edge portions (53a, 53b) with respect to said middle sagittal plane (π), at respective angles (α) centered on said sagittal axis (18) and measured from said middle sagittal plane (π), said respective angles (α) being established between 30 ° and 90 °, characterized in that each element of support (30, 30 ', 40, 65', 65 ", 70, 70 ') comprises: - a first longitudinal portion (38a, 68a) and a second longitudinal portion (38b, 68b), which provide a surface portion support (32) for said edge portions (53a, 53b) of said adjacent upper and lower vertebral bodies, respectively (13a, 13b) , said support surface portion 30 (32) of said first longitudinal portion (38a, 68a) and said support surface portion (32) of said second longitudinal portion (38a, 68a) having a predetermined relative position； - interfac
