An orthopedic implantable device articulately connects a first spinal vertebra (92) to an adjacent second vertebra (94) along the midline (102) of the first and second vertebrae or along an axis medial to the facets (46). The device includes a first component (110) having a male articulation member (119) and a second component (120) having a female articulation member (117). The first and second components (110, 120) are adapted to be attached to posterior locations of the first and the second vertebrae (92, 94), respectively. The first component (110) is articulately connected to the second component (120) by engaging the male articulation member (119) to the female articulation member (117) or vice versa. The articulation mechanisms may be a hook and loop or a hinge. First and second components (110, 120) are configured to replace the natural lamina, spinous process, pars interarticularis, and/or facets of the corresponding first and second vertebrae (92, 94).
