SUMMARY: We report 3 cases of vertebroplasty-induced intraspinal leakage of bone cement that were referred to us for management. Two patients received decompressive surgery, and one received rehabilitation. The gross surgical finding of yellowish dura mater and intradural fibrosis, adhesion, and microscopic finding of arachnoid membrane fibrosis are suggestive of late effect of thermal injury. These patients had residual lower extremity weakness and urinary and stool problems 13 months, 3 years, and 4.75 years postvertebroplasty, respectively.
