A pelvic X-ray shows sacral bone defect (a). The axial (b) and sagittal (c) CT scan of lumbosacral area shows a hypodense penetrating object that was introduced from the posterior aspect of the sacrum and then stopped in the S1 vertebral body. Also, intraoperative illustration can be observed before (d) and after (e) wood removal.

The pelvic X-ray showed an area of defect in the sacral region (Figure 1(a)). The computed tomography (CT) of the spine revealed a hypodense penetrating object that was introduced from the posterior aspect of the sacrum into the dural space and then stopped in the S1 vertebral body, and the object did not penetrate the anterior cortex of the vertebral body (Figures 1(b) and 1(c)).Because of the possibility of pelvic organ injury in cases of penetrating sacral injury, we consulted with an expert general surgeon. Muscle dissection revealed a wooden foreign body on the sacral lamina that passed into the S1 body (Figure 1(d)). Also, a portion of the patient's clothes was removed from the vertebral body (Figure 1(e)).
