Balloon kyphoplasty for osteoporotic spinal fractures with middle column compromise

摘要

Background: Balloon kyphoplasty (BKP) is an effective method for osteoporotic vertebral compression fractures. However osteoporotic spinal fractures with middle column compromise are mentioned as a relative contraindication to BKP. Thus we investigated the safety and efficacy of BKP in the treatment of osteoporotic spinal fractures with middle column compromise but without neurological deficit. Methods: In this retrospective study, 45 patients who suffered osteoporotic fractures with middle column compromise but without neurological deficits were treated by BKP from May 2007 to December 2010. The final follow-ups were finished during the time of July 2011-September 2011. The mean follow-up period was 20.2 months. The height of the compromised vertebral body, the kyphotic angle and spinal canal compromise were measured before surgery, one day after surgery, and at the final follow-up. A visual analogue scale (VAS) and the Oswestry disability index (ODI) were chosen to evaluate pain and functional activity.
