Abstract

A positioning frame for supporting a patient to facilitate different surgical approaches to the spine includes a main support beam, first and second support structures, a torso-lift support, and a pelvic-tilt support. The main support beam has a first end, a second end, and a length extending between the first and second ends. The main support beam defines an axis of rotation relative to at least a first support structure and a second support structure, and the axis of rotation substantially corresponds to a cranial-caudal axis of the patient when the patient is supported on the positioning frame. The first and second support structures support the main support beam, and space the main support beam from the ground. The torso-lift support is attached to the main support beam, and is configured to pivot a chest support plate between at least a first position and a second position to move the torso of the patient between an unlifted position and a lifted position. The pelvic-tilt support is attached to the main support beam, and is configured to support the thighs and the lower legs of the patient. Portions of the pelvic-tilt support are pivotal with respect to one another to facilitate adjustment of the hips of the patient.
