Objective: Percutaneous sacroplasty (PSP) is widely used in the clinic for osteoporotic sacral insufficiency fractures; however, few reports have described the safety and effectiveness of PSP for painful sacral metastases at the sacral ala under fluoroscopy alone. We aimed to evaluate the safety and efficacy of fluoroscopy-guided PSP for painful metastases at the sacral ala.
Patients and Methods: Thirty-five consecutive patients (median age, 60.74 ± 12.74 years), with a total of 41 metastatic lesions at the sacral ala, were treated with PSP. The patients were followed up for periods ranging from 1 month to 30 months (average, 8.23 ± 6.75 months). The visual analog scale (VAS), Oswestry Disability Index (ODI), and Karnofsky Performance Scale (KPS) were used to evaluate pain, mobility, and quality of life before the procedure and at 3 days and 1, 3, 6, 12, and 18 months after the procedure.
Results: Technical success was achieved in all patients. The minimum follow-up duration was 1 month. The mean VAS scores declined significantly from 7.20 ± 0.93 before the procedure to 3.43 ± 1.38 by day 3 after the procedure, and was 3.13 ± 1.07 at 1 month, 3.17 ± 1.15 at 3 months, 2.91± 1.38 at 6 months, and 2.57 ± 1.51 at 12 months after the procedure (P < 0.001). After PSP, analgesic drug administration had been discontinued in 31 of 35 patients (88.57%). The ODI and KPS also changed after PSP, with significant differences between the baseline scores and those at each follow-up examination (P < 0.001). Extraosseous cement leakage occurred in 12 cases without any major clinical complications.
Conclusion: PSP is a safe and effective technique for the palliative treatment of painful metastases involving the sacral ala under fluoroscopic guidance alone. It can relieve pain, reduce disability, and improve function, and is associated with minimal complications.
