<p>A lateral offset connector (10) is provided for engaging a spinal rod (40) to a vertebral fixation element, such as a hook or a bone screw (50). The lateral offset connector (10) includes a head portion (11) from which a pair of parallel arms (14) extend to form a slot opening (20) between the arms (14), the arms (14) having groves (17) on their underside for receiving the spinal rod (40). The eyebolt (45) is disposed between the arms (14) of the connector (10) in the slot opening (20), and a nut (48) is threaded onto the threaded post (47) of the eyebolt (45) to clamp the spinal rod (40) to the offset connector (10). The offset connector (10) further includes a threaded post (30) extending from one end for engagement with the spinal fixation component (50). A nut (32) clamps the fixation component (50) between a rounded shoulder (25) of the connector and the nut (32). The lateral offset connector (10) of this invention eliminates the need for contouring the rod in the saggital plane to connect to a fixation element.</p> |
