ABSTRACT
PURPOSE:
This study aims to investigate the relationship between cement leakage into the disc during percutaneous balloon kyphoplasty and subsequent compression fractures in adjacent vertebrae during treatment of osteoporotic vertebral compression fracture. MATERIALS ANDMETHODS:
103 patients (118 vertebrae) who have been treated with balloon kyphoplasty due to osteoporotic compression fracture from June 2007 to July 2010 were retrospectively analyzed. The group was composed of 13 males and 90 females. The mean age was 75 years (57~95 years). The mean follow-up period was 10 months (6~30 months). Patients were divided into two groups; one with cement leakage into the disc and the other without cement leakage into the disc. The study was performed to determine whether subsequent compression fractures in adjacent vertebrae were related to several factors.RESULTS:
The cement leakages into the disc occurred in 16 of 118 vertebrae. Of the 16 vertebrae with cement leakage into the disc, 5 (31%) had subsequent adjacent vertebral compression fractures; however, of the 102 vertebrae in which cement leakage did not occur, only 11 (11%) had subsequent adjacent vertebral compression fractures (p<0.05). Of the 16 vertebrae with cement leakage into the disc, subsequent adjacent vertebral compression fractures occurred 1 vertebrae of 10 vertebrae with definite trauma history. Out of the 6 vertebrae with cement leakage and no definite trauma history, 4 vertebrae (67%) had subsequent adjacent vertebral compression fractures (p<0.05).CONCLUSION:
The cement leakage into the disc significantly increases the incidence of subsequent adjacent vertebral compression fractures. Most of the subsequent fractures occurred in the early post-operative period. When cement leakage into the disc occurred in patients with no definite trauma history such as slip down, the incidence of subsequent adjacent vertebral compression fracture increased significantly.
