Patient positioning system

1. A patient positioning system configured for positioning and supporting a patient against movement on an operating table, the positioning system comprising:

a pair of scapular wedges each configured to be positionable to underlie a scapula of the patient when the patient is lying on the operating table, each of the scapular wedges having a planar base and an angled leg;

a head positioner configured to support a head and neck of the patient when the patient is lying on the operating table, the head positioner having a planar base positionable, an inclined neck trough angled upwardly from the planar base of the head positioner, and an uppermost portion of the inclined neck trough meeting and merging with a generally horizontal head trough; and

a pair of arm positioners each configured to be positionable about an arm of the patient when the patient is lying on the operating table, each of the arm positioners having a triangular wedge with a planar base and an angled leg, an end of the triangular wedge of the arm positioner is located to extend between the base of the arm positioner and the leg of the arm positioner and configured to abut the arm of the patient to position and anchor the arm against movement and to support a sacrum of the patient at a base of a spine of the patient and offload pressure from the sacrum; an upper flexible flap extending away from the angled leg of the arm positioner adjacent the end of the triangular wedge of the arm positioner; and a lower flexible flap extending away from the base of the arm positioner adjacent the end of the triangular wedge of the arm positioner, the upper flexible flap and the lower flexible flap configured to be oppositely wrapped around the arm of the patient to snugly envelope the arm and secure it relative to the triangular wedge of the arm positioner.

2. The patient positioning system of claim 1 , wherein the angled leg of the scapular wedge is angled upwardly from the planar base of the scapular wedge at an angle of from about 15 degrees to about 45 degrees.

3. The patient positioning system of claim 1 , wherein the inclined neck trough of the head positioner is angled upwardly from the planar base of the head positioner at an angle of from about 30 degrees to about 60 degrees.

4. The patient positioning system of claim 1 , wherein the angled leg of the arm positioner is angled upwardly from the base of the arm positioner at an angle of from about 10 degrees to about 30 degrees.

5. The patient positioning system of claim 1 , wherein the end of the triangular wedge of the arm positioner is configured as a concave surface.

6. A patient positioning system configured for positioning and supporting a patient against movement, the positioning system comprising: an arm positioner configured to be positionable about an arm of the patient, the arm positioner having a triangular wedge with a planar base and an angled leg, an end of the triangular wedge of the arm positioner is located to extend between the base of the arm positioner and the angled leg of the arm positioner and configured to abut the arm of the patient to position and anchor the arm against movement and to support a sacrum of the patient at a base of a spine of the patient and offload pressure from the sacrum; an upper flexible flap extending away from the angled leg of the arm positioner adjacent the end of the triangular wedge; and a lower flexible flap extending away from the base of the arm positioner adjacent the end of the triangular wedge, the upper flexible flap and the lower flexible flap configured to be oppositely wrapped around the arm of the patient to snugly envelope the arm and secure it relative to the triangular wedge.

7. The system of claim 6 , wherein the end of the triangular wedge is configured as a concave surface.
