Abstract |
Percutaneous vertebroplasty is a minimally invasive technique to relieve pain and to provide strength. However, several complications are reported, including bleeding at puncture site, local infection, leakage of cement, pulmonary embolism. We report a rare complication of delayed bursting fracture with anterior displacement of Polymethyl- methacrylate(PMMA) cement after percutaneous vertebroplasty.
A 68-year-old man suffered from severe lower back pain after slipped down injury was diagnosed as L1 compression fracture. We performed a percutaneous vertebroplasty to relieve his persistent pain. After 3 months later, he complained a severe back pain again. Imaging studies revealed a newly development of bursting fracture and anterior displacement of PMMA cement on L1 vertebral body.
We performed posterior transpedicular screw fixations from T11 to L3 with posterolateral autograft fusion, and intrao- peratively we injected additional PMMA bone cement into L1 vertebral body.
We report a rare complication of delayed bursting fracture with anterior displacement of PMMA cement following percutaneous vertebroplasty. It is likely to occur in osteoporotic vertebral fracture with anterior cortical defect. Also, more careful consideration to viscosity of cement and injection pressure are mandatory in those cases. |
