    (A)–(C) Radiographs of a 16-year-old girl with right vertical unstable sacral fractures and right femur fractures, showing a preoperation anteroposterior x-ray, computed tomography (CT) coronal and 3-dimensional view and (D) the immediate postoperative scans after reduction and internal fixation. (E). Postoperative anteroposterior x-ray at the second month. (F) Loosening of the hardware was detected at the fifth month. (G)–(H) A follow-up view at the 10th month. (I) The anteroposterior x-ray at the 11th month indicates hardware removal; no loss of reduction was detected.
