Zusammenfassung:The present invention relates to a clamp, and, more particularly, to a clamp for securing the position of a bone anchor with respect to a longitudinal rod, preferably for use in the spine. The clamp may include a housing, a rod clamping assembly, and a bone anchor clamping assembly. The clamp preferably enables the longitudinal axis of the rod to be offset or laterally displaced from the longitudinal axis of the bone anchor. The rod clamping assembly and the bone anchor clamping assembly are preferably moveably coupled to the housing in order to provide increased flexibility to better accommodate the location and geometry of the longitudinal rod and to better accommodate bone positioning.
