Zusammenfassung:To evaluate the efficacy and safety of combined microwave ablation (MWA) and vertebral augmentation (VA) in the treatment of spinal metastases with posterior wall defects. A retrospective review was conducted for 67 patients (42 men, 25 women) with painful spine metastases and posterior wall defects who underwent MWA combined with VA. Among these patients, 52 vertebrae had no epidural invasion and 33 had mild invasion but did not compress the spinal cord. Procedural effectiveness was determined by comparing visual analog scale (VAS) scores and Oswestry disability index (ODI) scores before the procedure and during the follow-up period. The procedure was technically successful in all patients. The mean VAS score declined significantly from 6.85 ± 1.81 before the procedure to 3.27 ± 1.97 at 24 h, 1.96 ± 1.56 at 1 week, 1.84 ± 1.50 at 4 weeks, 1.73 ± 1.45 at 12 weeks, and 1.71 ± 1.52 at 24 weeks post-procedure (p < 0.01). The mean ODI score was lower post-procedure than before the procedure (p < 0.001). Transient nerve injury occurred in two patients (SIR classification D), and the incidence of asymptomatic bone cement (SIR classification A) was 43.5% (37/85). MWA combined with VA is an effective and safe treatment for painful spine metastases with posterior wall defects.
