The supine position for elbow surgery [PDF]

Annals of The Royal College of Surgeons of England, 2012
It is not possible to turn patients who have spinal injuries, unstable pelvic injuries requiring an external fixator and polytrauma patients prior to spinal clearance. We describe a simple technique to overcome these problems while maintaining the access required for emergent and elective elbow surgery.
