多达三分之一的BKP治疗病例显示，由于球囊回缩后恢复的高度和后凸重新对准丢失，没有明显的高度恢复。这一缺点需要一种改进的方法，以保持完全充盈的球囊达到的高度和重新对准，直到通过PMMA基骨水泥固定椎体。恢复椎体的生理高度以缓解疼痛并防止相邻和远端椎体进一步骨折必须是这种方法的主要目的。一种新的椎体支架系统（VBS）在球囊放气后稳定椎体，直至骨水泥固定。介绍了应用VBS的前100例病例的影像学和安全性结果。在一项正在进行的国际多中心RCT的计划阶段，从图表和X线片中回顾性转录了影像学、手术和随访细节，以开发和测试病例报告表。在第一/资深作者所在机构集中评估X光片。100例患者（62例骨质疏松症患者）共103个骨折椎体接受了VBS系统治疗。女性49例，平均年龄73.2岁;男性66.7岁。术前平均前-中-后高度分别为20.3-17.6-28.0 mm。平均局部后凸角为13.1°。平均术前Beck指数（前缘高度/后缘高度）为0.73，平均替代Beck指数（中间高度/后缘高度）为0.63。术后平均高度分别恢复至24.5-24.6-30.4 mm。平均局部后凸角减小至8.9°。术后平均Beck指数为0.81，平均替代指数为0.82。总挤压率为29.1%，症状性挤压率为1%。在骨质疏松亚组中，有23.8%的挤出。在3个月的随访间隔内，有9%的邻近骨折和4%的远端新骨折，均发生在骨折组。VBS显示了其优势，特别是在挤压和双凹骨折的重新排列。考虑到存在骨折活动性，重新对线的可能性是合理的，并随着术前椎体变形的严重程度而增加。
Up to one third of BKP treated cases shows no appreciable height restoration due to loss of both restored height and kyphotic realignment after balloon deflation. This shortcoming has called for an improved method that maintains the height and realignment reached by the fully inflated balloon until stabilization of the vertebral body by PMMA-based cementation. Restoration of the physiological vertebral body height for pain relief and for preventing further fractures of adjacent and distant vertebral bodies must be the main aim for such a method. A new vertebral body stenting system (VBS) stabilizes the vertebral body after balloon deflation until cementation. The radiographic and safety results of the first 100 cases where VBS was applied are presented. During the planning phase of an ongoing international multicenter RCT, radiographic, procedural and followup details were retrospectively transcribed from charts and xrays for developing and testing the case report forms. Radiographs were centrally assessed at the institution of the first/senior author. 100 patients (62 with osteoporosis) with a total of 103 fractured vertebral bodies were treated with the VBS system. 49 were females with a mean age of 73.2 years; males were 66.7 years old. The mean preoperative anterior-middle-posterior heights were 20.3-17.6-28.0 mm, respectively. The mean local kyphotic angle was 13.1°. The mean preoperative Beck Index (anterior edge height/posterior edge height) was 0.73, the mean alternative Beck Index (middle height/posterior edge height) was 0.63. The mean postoperative heights were restored to 24.5-24.6-30.4 mm, respectively. The mean local kyphotic angle was reduced to 8.9°. The mean postoperative Beck Index was 0.81, the mean alternative one was 0.82. The overall extrusion rate was 29.1%, the symptomatic one was 1%. In the osteoporosis subgroup there were 23.8% extrusions. Within the three months followup interval there were 9% of adjacent and 4% of remote new fractures, all in the osteoporotic group. VBS showed its strengths especially in realignment of crush and biconcave fractures. Given that fracture mobility is present, the realignment potential is sound and increases with the severity of preoperative vertebral body deformation.
