Preparation of the endpoint, fracture midpoint, and frame. Because it was not credible to directly place these markers on the injured and deformed fragments, we used postreduction images to make the measurement process more accurate. The uninjured clavicle was used as a template. The 3D images of the main fragments of the injured clavicle were identified and reduced to the template. After identifying the endpoints, fracture midpoint, and frame in the postreduction status, we transformed the markers back to the prereduction position to obtain the initial coordinates
