Abstract

Kyphoplasty (KP) with intravertebral reduction devices (IRD) was reported to be associated with better radiological outcomes than KP with balloons (BK) for osteoporotic vertebral compression fractures (OVCFs). However, the mechanical factors that contribute to the radiological benefits of IRDs require further investigation. To probe the mechanical factors, this retrospective matched cohort study was designed, including the older patients with painful OVCFs and treated with KP. We compared the clinical and radiological outcomes between KP with an IRD and BK, where vertebral body height and kyphotic angle of the cemented vertebrae were measured pre- and postoperatively; clinical outcomes were collected by telephone interviews. The restoration and maintenance ratio suggested that IRDs were associated with favorable effects long-term wise in anterior to middle vertebral body and kyphosis than BK in patients. The gathered results concluded the radiological benefits of IRD regarding both its efficient restoration and maintenance in vertebrae.
