Is portable ultrasonography accurate in the evaluation of Schanz pin placement during extremity fracture fixation in austere environments?

Objective: The purpose of this study was to investigate the efficacy of ultrasonography to confirm Schanz pin placement in a cadaveric model, and the interobserver repeatability of the ultrasound methodology.

Design: This investigation is a repeated measures cadaveric study with multiple examiners.

Participants: Cadaveric preparation and observations were done by an orthopaedic traumatologist and resident, and two general surgery traumatologists.
