Background: Although percutaneous vertebral augmentation (PVA) is a commonly used procedure for treating vertebral compression fracture (VCF), the risk of vertebral refracture should be considered. Chronic kidney disease-mineral and bone disorder (CKD-MBD) is a systemic disease of mineral and bone metabolism. It is associated with an increased risk of fracture. Few studies have reported the use of PVA in patients with CKD-MBD. We herein report a rare case wherein the cemented vertebra and the adjacent vertebra refractured simultaneously in a CKD-MBD patient after PVA.
Case summary: A 74-year-old man suffered from low back pain after taking a fall about 3 wk ago. According to physical examination, imaging and laboratory findings, diagnoses of T12 VCF, CKD-MBD, and chronic kidney disease stage 5 were established. He then received percutaneous vertebroplasty at T12 vertebra. Fourteen weeks later, he presented with T12 and L1 vertebral refractures caused by lumbar sprain. Once again, he was given PVA which was optimized for the refractured vertebrae. Although the short-term postoperative effect was satisfactory, he reported chronic low back pain again at the 3-month follow-up.
Conclusion: It is necessary that patients with CKD-MBD who have received PVA are aware of the adverse effects of CKD-MBD. It may increase the risk of vertebral refracture. Furthermore, the PVA surgical technique needs to be optimized according to the condition of the patient. The medium- and long-term effects of PVA remain uncertain in patients with CKD-MBD.
