case_images: Relevant information was obtained based on the previous radiological images, which were performed in another center prior to primary surgery (Figure 2).
case_images: Headless screw that was broken came out with the help of a thin Kirschner wire attached to the reamer and turned in the opposite direction.

case_images: A more antegrade central fixation was carried out with a 2.8-mm headless screw (Acutrak ; Acumed LLC, OR, USA) after the bone grafting was completed (Figure 4).
