Balloon kyphoplasty後に骨セメントが前方移動したParkinson病の1例

抄録

  A 60-year-old woman presented with unbearable low back pain without any sign of external injuries. Magnetic resonance imaging and computed tomography revealed vertebral compression fracture of the L2 body. She had had Parkinson's disease for over a decade and underwent a posterior lumbar interbody fusion at the L3/4level 3 years ago. A balloon kyphoplasty (BKP) was performed 1 month after the onset of the symptoms of low back pain. Subsequently, anterior cement migration occurred within 4 months after BKP. It is thought that both Parkinson's disease and adjacent segment fusion might have caused the dislodgment of cement.

  This case emphasizes the importance of early treatment of vertebral fractures in patients with Parkinson's disease and serial follow-up after fusion.
