Abstract

Objectives: To explore the safety and efficacy of graded infusion bone cement in the percutaneous balloon kyphoplasty for Kümmell's disease.

Methods: 22 patients with osteoporotic Kümmell's disease were treated by percutaneous balloon kyphoplasty from January 2006 to January 2009. There were 9 males and 14 females in this study. The mean age of the patients was 71 years (range from 67 to 89 years). The back pain was prolonged for 2.9 months ((ranged from 1 month to 2 years). bone cement leakage was evaluated by postoperative CT scanning. A Visual Analog Scale (VAS) and the Oswestry Disability Index (ODI) were chosen to evaluate pain status and functional activity.

Results: The mean follow-up was for 15 months (ranged from 9 to 36 months). Asymptomatic cement leakage occurred in five cases, no other complications arised. The VAS was 8.1 at preoperative, 2.3 at postoperative, 2.2 at final follow-up; and the ODI was 85.5 at preoperative, 28.9 at postoperative, 23.7 at final follow-up. There was statistically significant improvement in the VAS and ODI at the post-operative assessment compared with the pre-operative assessment (P < 0.05), while there were no statistically significant differences between postoperative and the final follow-up (P > 0.05).

Conclusions: The study suggests that the use of graded infusion of bone cement in balloon kyphoplasty is a safe and effective procedure for osteoporotic Kümmell's disease.
