1. A surgical patient support top for use with a foundation frame, the surgical patient support top comprising:

a support frame including a first rail, a second rail spaced apart from and parallel to the first rail, and a cross beam extending from the first rail to the second rail, and

a motion coupler including a connector configured to be coupled to the foundation frame, and a joint coupled to the connector and coupled to the cross beam of the support frame to slide and shift relative to the cross beam, wherein the joint includes an arm extending from the connector and into a beam slot formed in the cross beam.

2. The surgical patient support top of claim 1 , wherein the joint includes a first resilient bumper situated along a first side of the beam slot formed in the cross beam and a second resilient bumper situated along a second side, opposite the first side, of the beam slot formed in the cross beam.

3. The surgical patient support top of claim 2 , wherein the first resilient bumper and the second resilient bumper are formed from rubber.

4. The surgical patient support top of claim 1 , wherein the joint includes a retainer configured to resist removal of the arm from the beam slot formed in the cross beam.

5. The surgical patient support top of claim 4 , wherein the retainer includes a retainer pin extending through an arm slot formed in the arm and a spring extending from the retainer pin to the arm.

6. The surgical patient support top of claim 1 , wherein the first rail includes a number of indicators spaced at predetermined intervals along a length of the first rail, the second rail includes a number of indicators spaced at predetermined intervals along a length of the second rail, and each indicator on the first rail corresponds to an indicator on the second rail.

7. The surgical patient support top of claim 6 , wherein the indicators of the first rail and the indicators of the second rail are lines extending perpendicular to the lengths of the first rail and the second rail, respectively.

8. A surgical patient support top for use with a foundation frame, the surgical patient support top comprising:

a support frame including a first rail, a second rail spaced apart from and parallel to the first rail, and a cross beam extending from the first rail to the second rail, and

a motion coupler including a connector configured to be coupled to the foundation frame for movement about a horizontal axis so that the support frame is free to pivot relative to the foundation frame about the horizontal axis, and a joint coupled to the connector and coupled to the cross beam of the support frame for slidable movement relative to the cross beam so that the support frame is free to slide relative to the foundation frame, wherein the joint includes an arm extending from the connector and into a beam slot formed in the cross beam.

9. The surgical patient support top of claim 8 , wherein the beam slot is angled relative to the longitudinal axis of the cross beam so that the support frame shifts and slides relative to the cross beam in a plane that intersects the horizontal axis at only one point.

10. The surgical patient support top of claim 9 , wherein the joint includes a first resilient bumper situated along a first side of the beam slot formed in the cross beam and a second resilient bumper situated along a second side, opposite the first side, of the beam slot formed in the cross beam.

11. The surgical patient support top of claim 9 , wherein the joint includes a retainer configured to resist removal of the arm from the slot formed in the cross beam.

12. A surgical patient support apparatus comprising the surgical patient support top of claim 8 , the foundation frame, and means for applying traction to a head of a patient supported on the patient support top.

13. A surgical patient support apparatus comprising the surgical patient support top of claim 8 , the foundation frame, and casters coupled to the foundation frame, the casters being braked and released electrically, and an emergency manual caster release being coupled to the casters to release the brakes manually if electrical power is lost.

14. A surgical patient support apparatus comprising the surgical patient support top of claim 8 , the foundation frame, and an H-bracket and pin to couple the surgical patient support top to the foundation frame, the pin and the H-bracket each having a safety feature to prevent inadvertent decoupling between the surgical patient support top and the foundation frame.

15. A surgical patient support apparatus comprising the surgical patient support top of claim 8 , the foundation frame, and an in-line rotational drive operable to provide powered rotation of the surgical patient support top relative to the foundation frame.

16. The surgical patient support apparatus of claim 15 , further comprising a knob coupled to a shaft that is movable within a slot provided in a guide plate to move the in-line rotational drive between a powered mode for powered rotation of the surgical patient support top and a manual mode for manual rotation of the surgical patient support top.

17. A surgical patient support apparatus comprising the surgical patient support top of claim 8 , the foundation frame, and at least one patient support panel and a hinged clamp to secure the at least one patient support panel to the surgical patient support top, the hinged clamp including a jaw having at least one headed post and a flap hinged to the jaw, the flap having an opening with a wedge feature, the at least one headed post being received in the opening of the flap when the hinged clamp is in a closed position to secure the at least one patient support panel to the first rail of the surgical patient support top.
