An orthopedic implantable device articulately connecting a first spinal vertebra to an adjacent second spinal vertebra includes a pair of first components adapted to be attached to locations left and right of a midline of the first vertebra, respectively and a pair of second components adapted to be attached to locations left and right of a midline of the second vertebra, respectively. Each of the first components includes a body and a male articulation member attached to the first component body and each of the second components includes a body and a female articulation member attached to the second component body. The first components are articulately connected to the second components by engaging the male articulation members to the female articulation members, thereby articulately connecting the first vertebra to said second vertebra along lines left and right of the midlines and without crossing the midlines, respectively.
