Outcomes Associated with Functional Mobility and Pain Amelioration in 49 Patients After Sacroplasty: A Single-Center Study.

Abstract

This study aimed to determine the predictive factors for analgesic reduction and amelioration of mobility following percutaneous sacroplasty in patients with insufficiency fractures or metastatic lesions. A single-center retrospective analysis of 49 patients who underwent percutaneous sacroplasty for insufficiency fractures and sacral pathological lesions was conducted. Visual analog scale (VAS), Functional Mobility Scale (FMS), and Oswestry Disability Index (ODI) were assessed. All data were accessed immediately before and 1 month after the procedure. Thirty-one patients (63.3%) experienced a significant reduction in VAS score, 36 (73.5%) experienced amelioration of FMS, and 20 (40.8%) fell within the ODI at 1 month. The mean VAS score was 7.8 (median [min-max] = 8 [3-10]) preprocedure and 3.4 (median [min-max]=3 [0-8]) postprocedure. The mean ODI was 0.5 (median [min-max]=0.5 [0.3-0.8]) preprocedure and 0.3 (median [min-max]=0.3 [0-0.7]) postprocedure. The mean FMS was 2.6 (median [min-max]=3 [1-5]) preprocedure and 1.2 (median [min-max]=1 [0-4]) postprocedure. There was a statistically significant increase in VAS amelioration in patients without concomitant vertebroplasty (odds ratio=4.16, interval range [1.09; 15.79], P<0.05). Major complications were not observed. In terms of long-term satisfaction, only two patients reported that they would not undergo the same procedure again. Percutaneous sacroplasty was effective for pain relief, functional outcomes, and short-term satisfaction. The absence of concomitant vertebroplasty was significantly associated with VAS improvements.
