1. A method of preventing inadvertent disconnecting of a patient support structure from a base structure, the patient support structure configured for supporting a patient above a floor during a medical procedure, the patient support structure including an end releasably coupled to a first end of a connection subassembly by a first pin extending through the first end of the connection subassembly and the end of the patient support structure, the base structure including a rotator member, the connection subassembly including a second end releasably coupled to the rotator member, the method comprising: removing the first pin from the first end of the connection subassembly and the end of the patient support structure; anddecoupling the rotator member and the second end of the connection subassembly, wherein decoupling of the rotator member and the second end of the connection subassembly is prevented until the first pin is removed, which permits movement of at least a portion of the connection subassembly relative to the rotator member, and allows the decoupling of the rotator member and the second end of the connection subassembly. 2. The method of claim 1, wherein the movement of the at least a portion of the connection subassembly relative to the rotator member includes sliding movement. 3. The method of claim 1, wherein the connection subassembly comprises a first arm and the at least a portion of the connection subassembly comprises a first locking member slidingly attached to the first arm. 4. The method of claim 3, wherein the movement of the at least a portion of the connection subassembly relative to the rotator member includes sliding the first locking member towards the first end of the connection subassembly. 5. The method of claim 1, wherein the second end of the connection subassembly is releasably coupled to the rotator member by a second pin extending through the second end of the connection subassembly and the rotator member, wherein the step of decoupling the rotator member and the second end of the connection subassembly comprises removing the second pin from the second end of the connection subassembly and the rotator member. 6. The method of claim 1, wherein the at least a portion of the connection subassembly comprises a first locking member slidably attached to a first arm of the connection subassembly. 7. A method of preventing inadvertent disconnecting of a patient support structure from a base structure, the patient support structure configured for supporting a patient above a floor during a medical procedure, the patient support structure including an end releasably coupled to a first end of a connection subassembly by a first pin extending through the first end of the connection subassembly and the end of the patient support structure, the base structure including a rotator block, the connection subassembly including a second end releasably coupled to the rotator block, the method comprising: decoupling the first end of the connection subassembly and the end of the patient support structure by removing the first pin from the first end of the connection subassembly and the end of the patient support structure; andallowing the second end of the connection subassembly to be decoupled from the rotator block by moving at had one portion of the connection subassembly relative to at least one cylindrical member extending laterally outward relative to a front face of the rotator block and extending laterally at least partially through the connection subassembly, wherein the removal of the first pin enables the moving of the at least one portion of the connection subassembly relative to the at least one cylindrical member. 8. The method of claim 7, wherein the movement of the at least one portion of the connection subassembly relative to the at least one cylindrical member is restrained to movement in a single degree of freedom. 9. The method of claim 7, wherein the single degree of freedom is translation. 10. The method of claim 7, wherein the connection subassembly comprises a first and a second arm spaced apart from each other. 11. The method of claim 10, wherein the at least one portion of the connection subassembly comprises a first and a second locking member, the first locking member being slidingly attached to the first arm, the second locking member being slidingly attached to the second arm. 12. The method of claim 7, further comprising decoupling the second end of the connection subassembly from the rotator block by removing a second pin extending through the connection subassembly and the rotator block. 13. The method of claim 7, wherein the at least one cylindrical member comprises a bolt. 14. The method of claim 7, wherein the at least one cylindrical member extends fully through an arm of the connection subassembly. 15. A method of preventing inadvertent disconnecting of a patient support structure from a base structure, the patient support structure configured for supporting a patient above a floor during a medical procedure, the patient support structure including an end releasably coupled to a first end of a connection subassembly by a first pin extending through the first end of the connection subassembly and the end of the patient support structure, the base structure including a rotator member, the connection subassembly including a second end releasably coupled to the rotator member, the method comprising: removing the first pin from the first end of the connection subassembly and the end of the patient support structure; anddecoupling the second end of the connection subassembly from the rotator member, wherein decoupling of the second end of the connection subassembly from the rotator member is prevented until the first pin is removed. 16. The method of claim 15, further comprising moving at least one portion of the connection subassembly relative to the rotator member to permit the decoupling of the second end of the connection subassembly from the rotator member. 17. The method of claim 15, wherein the connection subassembly comprises a first arm and a first locking member slidingly attached to the first arm. 18. The method of claim 17, wherein in order to decouple the second end of the connection subassembly from the rotator member, the first locking member must slide towards the first end of the connection subassembly. 19. The method of claim 15, wherein the second end of the connection subassembly is releasably coupled to the rotator member by a second pin extending through the second end of the connection subassembly and the rotator member, wherein the step of decoupling the second end of the connection subassembly from the rotator member comprises removing the second pin from the second end of the connection subassembly and the rotator member. 20. The method of claim 19, further comprising removing the connection subassembly from the rotator member after the second pin has been removed.
