The three methods for measuring post-fracture clavicular length compared in this study. Silva [14]: a line is drawn through the middle of each fragment. From each middle line, a perpendicular line between each fragment is drawn. Bone shortening is defined as the distance between the perpendicular lines on single anterior-posterior view. Hill [3]: a line is drawn from the bottom fragment perpendicular to the top fragment. Bone shortening is defined from the line to the tip of the top fragment on single anterior-posterior view. Lazardis [7]: the length of each clavicle is measured. Bone shortening is defined as uninjured clavicle length minus injured clavicle length on a panorama view
