Abstract: Disclosed is an implantable medical device, specifically a spinal cross-connector, for connection to approximately parallel spinal fixation rods, the spinal fixation rods being configured to attach to the vertebrae of the spine. The spinal cross-connector may be curved to facilitate installation of the cross-connector over the vertebrae of the spine and allow space for the muscles along the spinal column to heal. The spinal cross-connector may also provide three degrees of adjustment of the spinal cross-connector. The spinal cross-connector may be adjustable or telescoping to vary the width of the spinal cross-connector according to an individual's anatomy and the distance between the spinal fixation rods. The spinal cross-connector may also facilitate rotation of a longitudinal member around a vertical axis. The spinal cross-connector may also facilitate rotation of a longitudinal member around a longitudinal axis.
