A cross-connector system for connecting two rods of an implantable vertebral rod system utilizes relatively low-stress concentration contact areas between the connector elements and the rods. The cross-connector system includes a two-piece, elongated member ( 100 ) that is adjustable lengthwise and has, at each end, hook-shaped ends ( 103, 112 ) which each cooperate with a rotatable, eccentric cam plug ( 117, 126 ) having a curved surface ( 118, 128 ) that engages and secures a rod to the hook-shaped end in a manner that optimally distributes load to minimize stress concentrations.
