The present application is directed to vertebral implant systems and methods of using the systems. In one embodiment, the vertebral implant system includes first and second implants each including opposing end plates that are independently adjustable to form an included angle. Each implant within the system may include a different included angle to fit within a different sized and/or shaped vertebral space. Tool engaging features may be positioned on each end plate. The features on the opposing end plates may be substantially parallel when the implant is oriented at its specific included angle. The parallel orientation provides for accurate positioning of the implant within the vertebral space and may also assist in attaching and detaching the implant from the insertion tool. Using the system may include determining an anatomical angle of the vertebral space. Once the angle is determined, one of the implants from the system is selected that best matches the anatomical angle. The selected implant is then positioned with the contact features being substantially parallel. The implant may then be engaged with the insertion tool and inserted into the vertebral space.
