Systems and methods for controlling multiple surgical variables

A surgical patient interface comprising:

• a base;
• a platform coupled to the base and including a first end and a second end, wherein the platform is configured to transition between a first position and a second position about a pivotable axis stationary relative to the base;
• a first abutment and a second abutment each adjustably coupled to the platform;
• wherein, in the first position, the platform extends between the first end and the second end in a substantially horizontal direction relative to the base, and the first abutment and the second abutment are separated by a first distance along the substantially horizontal direction, and
• wherein, in the second position, the platform extends between the first end and the second end in a substantially vertical direction such that a torso of a patient extends substantially in a vertical direction, and the first abutment and the second abutment are separated by a second, different distance along the vertical direction;
• and
• a load control module configured to adjust one or both of the first abutment and the second abutment to change a load on the patient when the platform is in the second position.
