Paragraph Number

10

Implementations may include one or more of the following features. The vertebral implant where the detent mechanism is further adapted to retain the rotatable structure in an unlocked orientation. The niche is defined in a straight section of the rim and where the detent mechanism may include a second ear extending from the rotatable structure and where the second ear is sized to be received in the niche when the rotatable structure is in an unlocked orientation. The pair of opposed arms may include a plurality of radial grooves formed in a bottom surface of the rotatable structure and a corresponding plurality of ridges defined on a head of each screw positioned within each of the pair of screw openings. The pair of opposed arms extend in opposite directions from each other such that the pair of opposed arms engage two screws positioned within the pair of screw openings when the rotatable structure is in the locked orientation. The bone plate further may include a rotation limiter adapted to engage the rotatable structure and limit a degree of rotation of the rotatable structure when the rotatable structure is in the locked orientation. The bone plate may include three pairs of screw openings and the vertebral implant may include three rotatable structures, each rotatable structure positioned in the bone plate and adapted to retain a pair of screws, each screw positioned within a screw opening.
