Vertebral system, implant and inserts for vertebral system

An intervertebral implant comprising:

• a body including a skeleton structure comprising open upper and lower surfaces and opposing side walls defining an interior cavity and including a respective opening through each of the opposing side walls into the interior cavity through each of the opposing side walls, the respective opening through each of the opposing side walls comprising a lattice structure, the interior cavity configured to receive one or more of a modular graft insert, bone graft, and substitute in a post-manufacturing process, wherein a leading end of the body comprises a solid beveled pointed edge and a trailing end of the body comprises a solid substantially flat edge, a height of the leading end being less than a height of the trailing end, the trailing end comprising first and second offset openings extending in a direction substantially parallel to an axis of insertion of the intervertebral implant and configured to receive a gripping end of an implantation instrument allowing gripping and/or holding of the intervertebral implant during surgical intervention;
• first and second laterally elongated passages oriented transverse to the axis of insertion, each configured to receive a corresponding bone anchor including at least one of a screw and a curved plate body to anchor the intervertebral implant to an endplate of a vertebra;
• and
• a reciprocal locking device that in an unlocked mode has a first angular orientation relative to a posterior wall and in a locked mode has a different second angular orientation relative to the posterior wall, wherein in the unlocked mode the reciprocal locking device is configured to enable each bone anchor to be moved forward and backward relative to a respective one of the first and second laterally elongated passages and in the locked mode the reciprocal locking device is configured to prevent each bone anchor from moving forward and backward once anchored in a vertebral surface.
