We report a rare case of delayed cement displacement after balloon kyphoplasty in patient with K$\ddot{u}$mmell's desease. A 78-year-old woman with K$\ddot{u}$mmell's desease at T12 level received percutaneous balloon kyphoplasty. Two months after surgery, the patient complained of progressive severe back pain. Computed tomographic scans revealed a breakdown of the anterior cortex and anterior displacement of bone cement. Although this complication is very rare, it is likely to occur in treatment of K$\ddot{u}$mmell's disease accompanying anterior cortical defect.
