FIG 2. Case 2, a 71-year-old woman with sacral insufficiency fracture.

A and B, Anteroposterior (A) and lateral (B) venograms do not clearly confirm needle tip placement within the sacrum. Again, notice the difficulty in confirming the needle tip location as being entirely intraosseous.

C and D, Anteroposterior (C) and lateral (D) fluoroscopic images show cement within the sacrum.

E, Postoperative pelvic CT scan shows cement within the left sacrum, but the right sacral injection has resulted in a portion of the cement being positioned within the posterior soft tissue
