Expandable Intravertebral Implant in Cancer-Related Vertebral Compression Fractures: A Retrospective Review of 36 Implantations

J Vasc Interv Radiol. 2022 Jan;33(1):14-18. doi: 10.1016/j.jvir.2021.10.002.

Abstract

The purpose of this retrospective review was to evaluate SpineJack implantation in cancer-related vertebral compression fractures in 13 consecutive patients (mean age, 62.8 years ± 18.8). A total of 36 devices were inserted at 20 levels (13 [65%] lumbar and 7 [35%] thoracic vertebrae), with a mean Spinal Instability Neoplastic Score of 9.1 ± 2.1. Vertebral height restoration was observed in 10 levels (50%), with a mean height restoration of 5.6 mm ± 2.2 (interquartile range [IQR], 4-7.5). A total of 6 cement leakages were observed in 3 (23%) patients without clinical consequences. No severe adverse events were observed. One adjacent fracture occurred. Average pain scores on the visual analog scale significantly improved from 5.5 ± 1.8 (IQR, 4-7) preoperatively to 1.5 ± 2.2 (IQR, 0-3.3) at 1 month (P < .01) and to 1.5 ± 1.3 (IQR, 0.3-2.8) at 6 months (P < .01). In this small cohort, SpineJack offered pain relief in cancer-related fractures without an observed increase in adverse events.
