Outcomes of different minimally invasive surgical treatments for vertebral compression fractures: An observational study

Figure 1 Ratio of the preoperative visual analog scale score/postoperative visual analog scale score. There was no significant different between any of the surgical treatments 1 year postoperatively. VAS: Visual analog scale; VP: Vertebroplasty; KP: Kyphoplasty; IVEP: Intravertebral expandable pillar; SJ: SpineJack; pre-op: Preoperatively; post-op: Postoperatively.

Figure 2 Ratio of 1-year postoperative average body height/preoperative average body height. The vertebroplasty group had the worst performance in terms of average body height. ^aP < 0.05. AVBH: Average body height; VP: Vertebroplasty; KP: Kyphoplasty; IVEP: Intravertebral expandable pillar; SJ: SpineJack; post-op: Postoperatively.

Figure 3 Ratio of the 1-year postoperative kyphotic angle/preoperative kyphotic angle. The vertebroplasty group had the worst performance in terms of kyphotic angle correction. ^aP < 0.05. KA: Kyphotic angle; VP: Vertebroplasty; KP: Kyphoplasty; IVEP: Intravertebral expandable pillar; SJ: SpineJack.

Figure 4 Rate of adjacent vertebral fractures. The highest rate of adjacent vertebral fracture occurred in the vertebroplasty group, with a rate as high as 17%. VP: Vertebroplasty; KP: Kyphoplasty; IVEP: Intravertebral expandable pillar; SJ: SpineJack.
