Abstract
Objective To evaluate the efficacy of bone-filling mesh container vertebroplasty (BFMCV) in treating Kummell′s disease. Methods Thirty-eight patients with Kummell′s disease, aged 66-88 yr, were divided into 2 groups (n=19 each) using a random number table method: percutaneous vertebroplasty group (group PVP) and BFMCV group.In group BFMCV, the balloon was removed and bone-filling mesh container was placed, polymethyl methacrylate bone cement was mixed until it was at drawing stage and then injected with a screw propeller.The visual analogue scale scores and Oswestry disability index were recorded before operation (T1) and at 1 day and 1 and 6 months after operation (T2-4). Cobb′s angle was measured at T1 and T2.The operation time and development of bone cement leakage and adjacent vertebral fractures were recorded. Results Compared with group PVP, the incidence of bone cement leakage was significantly decreased (P 0.05). Conclusion BFMCV can treat Kummell′s disease effectively and decrease the risk of bone cement leakage, and it is a safe and effective treatment method. Key words: Vertebroplasty; Kummell′s disease; Bone filling mesh bag
