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.
球囊扩张椎体后凸成形术（KP）联合椎体复位装置（IRD）治疗骨质疏松性椎体压缩性骨折（OVCFs）的影像学效果优于 KP 联合球囊（BK）。然而，IRDs 改善影像学效果的力学因素仍需要进一步研究。为了探究这些力学因素，本回顾性匹配队列研究纳入了接受 KP 治疗的老年疼痛性 OVCFs 患者。我们比较了 KP 联合 IRD 与 BK 的临床和影像学结果，在术前和术后测量了椎体的高度和骨水泥椎体的后凸角；通过电话访谈收集了临床结果。恢复和维持比表明，IRD 在中前位椎体和后凸角的长期效果优于 BK。研究结果表明，IRDs 在椎体的复位和维持方面都具有良好的影像学效果。
