The purpose of this study was to investigate if preoperative magnetic resonance (MR) imaging could predict the risk of cement leakage into the disc space during vertebroplasty.

Approval for this retrospective HIPAA-compliant study was obtained from the Institutional Board of Research Associates, with waiver of informed consent. Forty six patients (107 vertebrae) treated with vertebroplasty underwent preoperative MR imaging. The preoperative MR imaging were evaluated for vertebral body height, wedge angle, presence of cleft and cortical defect, and T2 hyperintensity in the adjacent disc space. The presence of cement leakage into the disc was evaluated on postoperative computed tomography. We used logistic regression analysis to analyze the association between cement leakage and the preoperative MR appearance.

Cement leakage was seen in 51 of 214 disc spaces (24%) adjacent to the treated vertebral bodies. Small vertebral body size, cortical defect in treated vertebral bodies and abnormal T2 hyperintensity in adjacent intervertebral discs were associated with cement leakage into the disc (P .05).

Cement leakage into the disc can be predicted on preoperative MR images.

Cement leakage in adjacent disc spaces during vertebroplasty can be predicted on preoperative MR imaging.
