Osteointegrable cervical corporectomy implant designed to replace a damaged vertebral body between two vertebral bodies adjacent to the deteriorated vertebral body, which comprises a cylindrical separator body (1) capable of housing graft material inside, and with an upper end (1a) and a lower end (1b), a plurality of side holes (5) communicated with the interior of the separator body for the introduction of graft material, upper anchoring means (6a) emerging from the upper end (1a) of the separator body (1) to anchor the implant to an adjacent upper vertebral body, and lower anchoring means (6b) emerging from the lower end (1b) of the separator body (1) to anchor the implant to an adjacent adjacent vertebral body, in which the separator body ( 1) comprises a reticular support structure comprising a plurality of laterally interconnected columns of unit cells (3) three-dimensional united them together； each unit cell (3) encloses an interior space (11) defined vertically between an upper base (3a) and a lower base (3b) of the unit cell (3)； the interior spaces (11) of the unit cells (3) are laterally delimited between vertical connection elements (2, 2a, 2b, 2c, 2d) that connect the respective upper and lower bases (3a, 3b) of the cells (3 ). characterized in that the columns of unit cells (3) of the reticular structure are formed by a plurality of vertical bars (2, 2a, 2b) joined together by braces (4) extending between vertical bars (2, 2a, 2b) neighbors； the interior space (11) of each unit cell (3) is laterally delimited between two vertical sections (2 ') of at least three neighboring vertical bars (2, 2a, 2b)； each vertical section (2, 2 ') is defined between the upper base (3a) and the lower base (3b) of the unit cell (3), and each tie rod (4) of a unit cell (3) that connects vertical bars (2, 2a, 2b) neighboring extends between the upper base (3a) and the lower base (3b) of the unit cell (3), so that the unit cells (3) form stacked layers of unit cells (3) .I
