<p>Devices and methods for spinal stabilization include first and second anchor assemblies (30) engageable to respective ones of first and second vertebrae and a connecting element (40, 40', 140, 240, 340, 440, 540, 640, 740, 840, 940, 1040, 1140) engageable to the first and second anchor assemblies (30). The connecting element (40, 40', 140, 240, 340, 440, 540, 640, 740, 840, 940, 1040, 1140) includes opposite first and second end members (44, 46, 144, 146, 244, 246, 344, 346, 444, 446, 544, 546, 644, 646, 744, 746, 844, 846, 944, 946, 1044, 1046, 1144, 1146) and a bumper assembly (48, 248, 348, 548, 748, 848, 948, 1048, 1148) between the end members that flexibly connects the end members so the connecting element (40, 40', 140, 240, 340, 440, 540, 640, 740, 840, 940, 1040, 1140) can provide dynamic stabilization of the spinal column when engaged to the anchor assemblies (30).</p> |
