On the initial examination, a plain radiograph showed a fracture of the left pubic rami (Figure 2A), and CT showed an H-shaped fracture of the sacrum (Figures 2B, C), so FFP type IVb was diagnosed. SIRF was performed in response to failed conservative therapy due to delayed diagnosis (Figure 2D, E). Bone union was achieved 3 months after surgery (Figures 2F, G).
