1. A system for anterior fixation of a spine, the system comprising:
a multi-level vertebral plate comprising:
an upper portion and a lower portion,
a longitudinal axis extending along a length of the vertebral plate,
a concave superior edge and a convex inferior edge connected by a plurality of curved perimeter edges, the superior, inferior, and perimeter edges together defining a profile of the vertebral plate which is entirely curvilinear,
an exterior surface,
an interior surface configured such that the longitudinal axis is configured to align with a median plane of the spine,
wherein the superior edge defines an upper-most extent of the upper portion and is curved continuously between a first perimeter edge and an opposing second perimeter edge of the plurality of curved perimeter edges,
wherein the superior edge comprises a cambered slope and is curved between the interior surface and the exterior surface, and
a plurality of fastener apertures, the plurality of fastener apertures comprising in the upper portion a single fastener aperture and a first set of fastener apertures directly adjacent to the single fastener aperture, and in the lower portion a second set of fastener apertures;
wherein the vertebral plate is configured such that when the longitudinal axis is aligned with the median plane, only the single fastener aperture in the upper portion is juxtaposed adjacent to a first vertebra of the spine and is on a first side of the median plane, the first set of fastener apertures is juxtaposed adjacent to a second vertebra of the spine, and the second set of fastener apertures is juxtaposed adjacent to a third vertebra of the spine with one aperture of the second set of fastener apertures on a second side of the median plane, and wherein the single fastener aperture is coaxial with at least one of the first set of fastener apertures and at least one of the second set of fastener apertures.
