Intradural Bone Cement Leakage Following Percutaneous Vertebroplasty

ABSTRACT

Bone cement extravasation is a frequent occurrence after percutaneous vertebroplasty(PVP) using polymethylmetacrylate(PMMA) for the treatment of osteoporotic vertebral compression fracture. Fortunately, major neurological complication is rare in spite of potential occurrence. The authors reported a case of in a 67-year-old woman whom a intradural cement leakage provoked left leg weakness with hypesthesia and paresthesia below the area of the left L1 dermatome. Emergency laminectomy with removal of intradural bone cement for decompression was performed. After operation, her pain resolved, but left leg weakness was persistent. PVP using PMMA are now being used wide spreadly for osteoporotic vertebral compression fracture as minimally invasive and safe procedure, but the potential risks of major complication exist always. We experienced a rare case of intradural bone cement leakage after PVP using PMMA,
