골다공증성 척추체압박골절에서 경피적 풍선 척수후만성형술의 치료결과

Abstract

Percutaneous balloon kyphoplasty (PBK) is a more recent technique which applies the principles of balloon angioplasty to vertebroplasty. It is a widely accepted method which achieves the restoration of vertebral height and the correction of kyphotic deformity with little complication in osteoporotic vertebral compression fractures (OVCF). This study was performed to analyze pain relief, deformity correction and complication rate after PBK for OVCF. The clinical and radiologic data of 52 vertebrae in 38 OVCF patients who underwent PBK between August 2004 and October 2005 were retrospectively reviewed. The patients had significant improvement of pain after the procedure. The visual analogue scale score improved significantly after the procedure. The midline height of vertebral body significantly increased postoperatively, and mean kyphotic angle show significant correction. During follow-up, one fracture adjacent to a treated level was observed. There was no serious complication except two case of epidural cement leakage without neurological impairment and 89.5% of the patients gained excellent or good results. PBK is an effective and safety method in the management of OVCF. It seems that PBK safely can reduce severe back pain, and the reduction of pain directly contributes to early improvements in quality of life and the ability to move independently. The midline vertebral height and kyphotic deformity can be restored significantly.
