A total of 47 percutaneous vertebroplasties (PVs) were performed for osteoporotic vertebral fractures in 31 patients, 25 PVs were performed using the frontal-opening cannula (FOC) and 22 using the new side-opening cannula (SOC), randomly distributed. The incidence of cement extrusion was 27% with the SOC, and 68% with the FOC, all asymptomatic (p<0.01). The pain control was similar for both groups, with good improvement of pain in most of the patients, and there were no clinical relevant complications. The cement leakage can be significantly reduced with this new SOC, which allows for a better cement injection toward the center of the vertebral body, increasing the safety of the procedure, with no increase in cost.
对31例骨质疏松性椎体骨折患者共实施了47例经皮椎体成形术（PV），其中25例使用前端开口套管（FOC）进行，22例使用新型侧方开口套管（SOC）进行，随机分布。SOC组骨水泥渗漏发生率为27%，FOC组为68%，均无症状（p<0.01）。两组的疼痛控制情况相似，大多数患者疼痛得到明显改善，且无临床相关并发症。这种新型SOC可显著减少骨水泥渗漏，它能使骨水泥更好地注入椎体中心，提高手术安全性，且成本未增加。
