BACKGROUND: Osteolysis has always occurred in pelvis. Percutaneous injection of bone cement stabilized bone fracture, relieved pain or even treated tumor. However, leakage of bone cement might cause severe complications. OBJECTIVE: To explore the therapeutic effect of percutaneous injection of bone cement on treating osteolysis pelvic disease in 9 cases by the CT guidance. METHODS: By the CT guidance, needing degree was determined firstly. Focal size and scanning layers were used to calculate focal volume and estimate injected dose of bone cement. Three-dimensional targeting device was used to introduce the puncturation. The bone cement which was 0.2-0.5 mL less than the calculated volume was injected into osteolysis site. The accuracy, injected dose, clinical efficacy, and complications were investigated. RESULTS AND CONCLUSION: The following-up ranged from 5 months to 4 years, with mean duration of 1.5 years. At 1-48 hours after operation, symptoms were recovered, including complete recovery (n=6), partial recovery (n=2), and light recovery (n=1). Leakage of bone cement was not detected out around focal region. This suggested that percutaneous injection of bone cement into the erosion site is an effective method to treat pelvic osteolysis disease, characterizing by security, effective, and less invasive.
