Abstract:
Objective To compare the clinical outcomes of dilator-kyphoplasty (DKP) and balloonkyphoplasty (BKP) in treatment of osteoporotic vertebral compression fractures. Methods From May 2007 to March 2009, 23 cases with 26 vertebrae were treated with DKP, while 29 cases with 29 vertebrae were treated with BKP procedures. The operating time, bleeding volume and injecting volume of cement were recorded during operation. The distribution of cement, the restoration of vertebral height and Cobb angle were observed. The patients' visual analogue scales (VAS) score and Oswestry disability index (ODI) score were evaluated after operation. Results There were no differences in operative time, bleeding volume of every vertebrae and cement injected volume between these two groups (P＞0.05). The vertebral height, Cobb angle, VAS and ODI scores were significantly improved than those of pre-operation in these two groups (P＜0.05). The height of the anterior vertebrae and Cobb angle in DKP groups were restored significantly than those in BKP groups (P＜ 0.05). There were 1 case (1 vertebra, 3.8%) underwent cement leakage in DKP groups and 5 cases (5 vertebrae, 17.2%) in BKP groups. Conclusion DKP and BKP were effective in the treatment of osteoporotic vertebral compression fractures. The height of the anterior vertebrae and Cobb angle in DKP groups were restored significantly than those in BKP groups.
