Fig. 1Preoperative simple AP (A) and lateral (B) L-spine radiographs show the intervertebral disc space narrowing and spondylolisthesis between L4/L5.
Fig. 2Coronal image (A) and saggital image (B) of pelvic CT scan shows bilateral sacral insufficiency fracture with cortical discontinuity (white arrow). T2 (C) and T1-weighted saggital image (D) of lumbosacral MRI show perilesional edema (white arrow).
Fig. 3Under fluoscopy guidance with balloon assistance, intraoperative C-arm AP image (A) and lateral image (B) show balloon inflation at the sacral insufficiency fracture site.
Fig. 4After fluoscopy-guided balloon-assisted sacroplasty, AP (A) and lateral (B) sacral radiographs, axial (C) and saggital (D) image of pelvic CT scan show the appearance of cement in the fracture area and no leakage of cement.
