title: Repeat percutaneous vertebroplasty at cemented vertebra with fluid sign and recurrent pain.
abstract: Six patients (three females and three males) were referred from their clinicians for evaluation with complaints of recurrent pain. A followup MRI showed fluid at the cemented vertebral bodies. Repeat percutaneous vertebroplasty (PV) was performed in these six patients at the cemented vertebrae. Pain scores, mobility scores, and spine MRIs before the 1st PV, prior to the repeat PV, and 1 and 3 months after the repeat PV were obtained. One month after the repeat PV, the six patients had a mean pain score reduction of 6.2 points and a mean postoperative pain level reduction of 2.8 points. Four of the six patients demonstrated an improvement in mobility with a 1.7 point mean decrease one month after the repeat PV. There was decreased fluid and bone marrow edema in four of the six patients on the follow-up MRIs one and three months after the repeat PV. Repeat PV at cemented vertebrae with fluid signs may offer therapeutic benefits for recurrent pain.
