case_images: Radiographic images revealed the transposition of the bone fragment, which was 12 mm at the time of the injury (Figure 1) and had now increased to 23 mm, and the fragment had enlarged (Figure 2).
case_images: The X-ray image at the first visit to our hospital, 11 months after the injury. The bone fragment is enlarged, and the transposition is about 23 mm (arrow).

case_images: Bone scintigraphy showed intense uptake in both sides of the nonunion site, ischial tuberosity, and bone fragment (Figure 3).
case_images: The X-ray image immediately after surgery. Two screws were inserted into her pelvic medulla in the direction to prevent them from penetrating the hip joint and to ensure the sufficient length.

case_images: Then, the hamstring tendon was fixed to the ischial tuberosity with three 2.3 mm-diameter suture anchors (Figure 4).
case_images: X-ray images 3 years after surgery. The bone fragment is firmly fused to her ischium.
