A clamp assembly includes a first jaw and a second jaw cooperatively positioned to receive the fixation element. A gate is displaceable relative to the first jaw and moveable between an open condition where the gate and the first jaw form an opening of a first size allowing introduction of the fixation element between the first and second jaws and a locking condition where the opening formed by the gate and the first jaw has a second size that prevents removal of the fixation element out from between the first and second jaws.

1. A clamp assembly configured to secure a fixation element of an external fixation assembly, comprising: a first jaw;a second jaw disposed relative to the first jaw, the first and second jaws cooperatively positioned to receive the fixation element; anda revolving gate moveable between an open condition and a provisionally locked condition, wherein: in the open condition, the gate and the first jaw form a first sized opening that allows the fixation element to be removed from and introduced between the first and second jaws; andin the provisionally locked condition, the gate and the first jaw form a second sized opening that prevents removal of the fixation element from between the first and second jaws, but allows the fixation element to slide and rotate relative to the first and second jaws,wherein the gate has a substantially cylindrical configuration with a relief formed therein, the relief being disposed in a manner that when the gate is in the open condition, the relief allows the fixation element to be removed from and introduced between the first and second jaws. 2. The clamp assembly of claim 1, further comprising a biasing element that is positioned and configured to bias the gate toward the provisionally locked condition. 3. The clamp assembly of claim 1, further comprising a release mechanism configured to displace the gate to the open condition allowing the fixation element to be removed from and introduced between the first and second jaws. 4. The clamp assembly of claim 3, wherein the release mechanism comprises a slider actuatable by a user and a gate release portion associated with the slider, wherein the slider and gate release portion are configured such that actuation of the slider manually displaces the gate release portion. 5. The clamp assembly of claim 4, wherein the slider is moveable between a neutral position, a forward position, and a rearward position, the neutral position of the slider corresponding to the provisionally locked condition of the gate. 6. The clamp assembly of claim 5, wherein movement of the slider into the forward position moves the gate to the open condition and movement of the slider into the rearward position causes the gate to expel the fixation element from the clamp. 7. The clamp assembly of claim 1, wherein the gate is moveable to the provisionally locked condition to prevent removal of the fixation element from between the first and second jaws without any relative movement of the first and second jaws. 8. A clamp assembly configured to secure a fixation element of an external fixation assembly, comprising: a first jaw;a second jaw disposed relative to the first jaw, the first and second jaws cooperatively positioned to receive the fixation element; anda revolving gate moveable between an open condition and a provisionally locked condition, wherein: in the open condition, the gate and the first jaw form a first sized opening that allows the fixation element to be removed from and introduced between the first and second jaws; andin the provisionally locked condition, the gate and the first jaw form a second sized opening that prevents removal of the fixation element from between the first and second jaws, but allows the fixation element to slide and rotate relative to the first and second jaws,wherein the gate has a substantially cylindrical configuration with a ramp formed therein, and movement of the gate from the open condition to the provisionally locked condition causes a progressive lessening of the distance between the ramp and a fixation element receiving slot in the first jaw. 9. The clamp assembly of claim 8, further comprising a biasing element that is positioned and configured to bias the gate toward the provisionally locked condition. 10. The clamp assembly of claim 8, further comprising a release mechanism configured to displace the gate to the open condition allowing the fixation element to be removed from and introduced between the first and second jaws. 11. The clamp assembly of claim 10, wherein the release mechanism comprises a slider actuatable by a user and a gate release portion associated with the slider, wherein the slider and gate release portion are configured such that actuation of the slider manually displaces the gate release portion. 12. The clamp assembly of claim 11, wherein the slider is moveable between a neutral position, a forward position, and a rearward position, the neutral position of the slider corresponding to the provisionally locked condition of the gate. 13. The clamp assembly of claim 12, wherein movement of the slider into the forward position moves the gate to the open condition and movement of the slider into the rearward position causes the gate to expel the fixation element from the clamp. 14. The clamp assembly of claim 8, wherein the gate is moveable to the provisionally locked condition to prevent removal of the fixation element from between the first and second jaws without any relative movement of the first and second jaws. 15. A clamp assembly configured to secure a fixation element of an external fixation assembly, comprising: a first jaw;a second jaw disposed relative to the first jaw, the first and second jaws cooperatively positioned to receive the fixation element;a revolving gate moveable between an open condition and a provisionally locked condition, wherein: in the open condition, the gate and the first jaw form a first sized opening that allows the fixation element to be removed from and introduced between the first and second jaws; andin the provisionally locked condition, the gate and the first jaw form a second sized opening that prevents removal of the fixation element from between the first and second jaws, but allows the fixation element to slide and rotate relative to the first and second jaws; anda lock configured to be actuated to prevent the fixation element from sliding and rotating relative to the first and second jaws, wherein the lock comprises:a post component disposed through respective holes in the first and second jaws; anda nut threadably engaging the post component and configured to be tightened to cause the first and second jaws to move relative to one another to prevent the fixation element from sliding and rotating relative to the first and second jaws. 16. The clamp assembly of claim 15, further comprising a biasing element that is positioned and configured to bias the gate toward the provisionally locked condition. 17. The clamp assembly of claim 15, further comprising a release mechanism configured to displace the gate to the open condition allowing the fixation element to be removed from and introduced between the first and second jaws. 18. The clamp assembly of claim 17, wherein the release mechanism comprises a slider actuatable by a user and a gate release portion associated with the slider, wherein the slider and gate release portion are configured such that actuation of the slider manually displaces the gate release portion. 19. The clamp assembly of claim 18, wherein the slider is moveable between a neutral position, a forward position, and a rearward position, the neutral position of the slider corresponding to the provisionally locked condition of the gate. 20. The clamp assembly of claim 19, wherein movement of the slider into the forward position moves the gate to the open condition and movement of the slider into the rearward position causes the gate to expel the fixation element from the clamp. 21. The clamp assembly of claim 15, wherein the gate is moveable to the provisionally locked condition to prevent removal of the fixation element from between the first and second jaws without any relative movement of the first and second jaws.
