Biomechanical resistance and surgical morbidity of spinal posterior pedicle screw fixation depend on the intraosseous position of the implants. Upper thoracic pedicle screws are particularly demanding given their convergence and thin character. We present our experience as military surgeons of freehand placement of upper thoracic pedicle screws supported solely by anteroposterior, i.e., frontal x-ray fluoroscopy. ⋯ Clinically, placement of upper thoracic pedicle screws supported solely by anteroposterior fluoroscopy appears to be safe. The surgical technique is simple enough to be used in settings with limited resources, such as a mobile field surgical team.
