Pilot ejection procedures show increased neck injury risk due to initial head-neck posture, indicating the need for proper positioning.
Initial head-neck posture markedly influences cervical loading and injury risk during ejection. Axial rotation presents the greatest risk by elevating vertebral stress and ligament tension, emphasizing the critical importance of maintaining a neutral posture to protect the cervical spine during pilot ejection.
