There are rarely few reports on the clavicular motion during elevation of the extremity. This is may due to the complicated shape of the clavicle and its three-dimensional movement. The purpose of this study is to analyze the movements of clavicle by using X-ray fluoroscope.The study was performed on a 21 years old female who had clavicular fracture a year ago and had fixation with plate and screws. She had no difference on both shoulder ROM when examined. In front of X-ray fluoroscope, she was asked to abduct her arm to full in 10 seconds, and the movements were recorded on videotape. From the location of plate and screws we analyzed the clavicular motion.The clavicle rotated clockwise in its long axis when viewing from the left sagittal plane. This movement increased constantly during the elevation of arm and reached 50 degrees at maximum abduction. In Frontal view, 25 degrees of upward movement was observed, where the majority of the movement was seen within 90 degrees of elevation.
