Abstract

Spinal fusion surgery is increasingly widely applied to elderly patients with osteoporosis. Altered biomechanics and/or poor bone quality can lead to vertebral fractures at the last vertebra of the fixation segment (13,2%). The treatment by surgery to widen the fixation segment faces many risks due to poor bone quality and elderly patients with many underlying diseases, while cement augmentation surgery is more and more widely applied due to its advantage of being less invasive, requiring only local anesthesia, and fast pain relief. However, cementing on fixed vertebrae encountered many difficulties due to anatomical changes after surgery; the position of the screw obscures the insertion of the cementitious needle through the pedicle and covers the anatomical landmarks on the image of C-arm. Therefore, this is a complex technique, and to our knowledge, no cases have been reported in Vietnam. We report a case of vertebral fracture at the top position of the fixed segment that was successfully treated by cement augmentation at Bach Mai Hospital.
