The present application generally relates to orthopedic stabilization systems, and in particular, to systems including clamps. The clamps can be used in addition to or to replace hooks that grasp onto bone members, such as the lamina. One example of such a clamp is an in-line clamp that includes a central opening for receiving a rod member, a first opening for receiving a set screw and a second opening for receiving an elastic member therethrough. Another example of such a clamp is an off-set clamp that includes an upper plate, a bottom plate, and an opening for receiving a rod therein. The upper plate can be separated from the bottom plate to make space for an elastic member that can be secured within the plates. Tulip clamps that utilize one or more elastic members are also provided. |

1. A surgical system comprising:
a clamp receiving a rod and an elastic member therein, wherein the elastic member extends around a portion of the rod and is configured to wrap around a bone member, wherein the clamp comprises a first lower opening, a second lower opening and an upper opening, wherein a first end of the elastic member passes through the first lower opening and a second end of the elastic member passes through the second lower opening such that both the first end and the second end of the elastic member can pass through the upper opening, an instrument configured to hold the clamp and tension the elastic member, the instrument comprising a clamp holder with tips for grasping the clamp and a tensioner driver for increasing tension on the elastic member, wherein the clamp further comprises a set screw opening, wherein a set screw is received in the set screw opening, and the set screw engages the elastic member when the set screw is positioned through the set screw opening, and wherein the upper opening is located between the first lower opening and the set screw opening and the set screw opening is located between the upper opening and the second lower opening. |
