Connectors (100,300) for interconnecting rods (150,152,340,342) fixed to vertebrae and other bones of a subject include a body portion (104,122,304,322) and two recesses (111,129) or pockets (306,324) for receiving the rods. These connectors are generally able to be secured to the rods by a tightening, a fastener (112,130) or retaining member (310,328) from above the spine, which can facilitate the procedure for the surgeon. The connectors (100,300) can include rotatable or stationary pockets, mating members (102,120,302,320) that pivot and/or translate within the coronal plane of the subject to adjust to the positions of the rods, and extension shafts that pivot to adjust for rod angle.
