Balloon kyphoplasty is now widely used for the treatment of vertebral compression fractures. Excellent pain relief is achieved with cement injection, but the safety of the procedure relays on excellent radiological exposure. The balloon kyphoplasty technique is usually performed using one or two C-Arm devices to allow correct antero-posterior (AP) and lateral view throughout the surgical procedure. By definition, this minimal invasive spine surgery is associated with radiation exposure for both the patient and the surgeon. In our center, we recently moved from this way of proceeding to the use of an O-Arm image guidance system to perform cement augmentation in vertebral fractures. To our knowledge, there is no clinical series describing the O-arm use in a balloon kyphoplasty procedure published in the scientific literature. We prospectively evaluate on 16 consecutive patients, the feasibility of the O-Arm guided kyphoplasty procedure with the original, usual tools, and we measured the fluoroscopy time and the X-ray exposure. We didn't experience any device related problem and demonstrated a significant reduction of X-ray exposure and time of fluoroscopy. We believe that using this new intraoperative system, the overall time of surgery and fluoroscopy could still be reduced in a near future.
球囊椎体后凸成形术目前广泛用于治疗椎体压缩骨折。通过注入骨水泥可实现显著的疼痛缓解，但该手术的安全性依赖于良好的放射学暴露。球囊椎体后凸成形术通常使用一台或两台C型臂设备进行，以便在整个手术过程中获得正确的前后位（AP）和侧位视图。根据定义，这种微创脊柱手术会使患者和外科医生都受到辐射暴露。在我们中心，我们最近从这种手术方式转变为使用O型臂图像引导系统来进行椎体骨折的骨水泥强化术。据我们所知，科学文献中尚无关于在球囊椎体后凸成形术过程中使用O型臂的临床系列报道。我们对16例连续患者进行前瞻性评估，使用原始的常用工具探讨O型臂引导下椎体后凸成形术的可行性，并测量了透视时间和X线暴露情况。我们未遇到任何与设备相关的问题，且结果显示X线暴露和透视时间显著减少。我们相信，使用这种新的术中系统，在不久的将来手术和透视的总时间仍可进一步缩短。
