CT-guided unilateral facet joint injection. The patient is a 97-year-old woman (patient 19 in Table 1) with recurrent back pain after T10 and T11 vertebral augmentation. Her initial back pain symptoms were localized to the right upper lumbar facet joints under fluoroscopic evaluation. She was pain-free after undergoing right L1-L2 and L2-L3 facet joint injections 2 weeks after vertebral augmentation. She returned 11 months after her vertebral augmentation procedure for new low-back-pain symptoms that localized to her SIJs and responded to bilateral SIJ injections.
