This study aimed to analyze a clinical case of complications following cement fixation and provide a detailed review of relevant literature. A 70-year-old patient underwent transpedicular screw instrumentation from L2-L4 with polymethyl methacrylate augmentation, which resulted in cement leakage into the spinal canal and subsequent pulmonary embolism. After revision surgery and conservative treatment for the embolism, the patient's condition stabilized, demonstrating that conservative measures can be effective in managing cement embolism. To complement this case, a comprehensive literature review was conducted to explore the causes, prevention, and treatment of complications related to cement augmentation. The findings support that while cement-augmented pedicle screw instrumentation remains a leading technique for osteoporotic fractures, the associated risks are manageable with proper treatment protocols.
