一种新型椎体替代(VBR)脊椎隔板移植物能够提供最大多骨生长区域，同时能够维持移植物的结构力量。

　　Crystal VBR脊椎隔板移植物是由Quantum Orthopedics(Carlsbad, CA, USA)公司制造的，具有优越的移植窗口和较大的内部移植空腔，能够进行最优化操作。移植物能够透过射线，具有射线密集标记，能够精确定位和放置，具有7种高度角度0°-7°。除此之外，VBR移植物单一方向的背脊设计能够防止移植物移动。Crystal隔板由Peek-Optima制作而成，这是一种生物兼容性质稳定的多聚乙醚酮聚合体，这是由Invibio(Lancashire, UK)公司制造的。这套系统包括一个颜色标记系统，确保外科医生能够安全迅速地进行手术。这套系统已经获得了美国食品药品管理局的批准。
 
　　Biocompatible Spinal Spacer Implant

　　A new vertebral body replacement (VBR) spinal spacer implant offers maximum bony in-growth area while maintaining implant structural strength.

　　The Crystal VBR spinal spacer implant, manufactured by Quantum Orthopedics (Carlsbad, CA, USA),features generous grafting windows and a large interior graft space for optimal performance. The implants are radiolucent with radio-dense markers to enable accurate positioning and placement, and are available in seven heights angled 0° and 7°. Additionally, the VBR implants feature uni-directional ridges designed to prevent implant migration. The Crystal spinal spacers are made from Peek-Optima, a biocompatible and stable polyetherketone polymer manufactured by Invibio (Lancashire, UK). The system includes a color-coded instrument system designed to enable the surgeon to safely and quickly perform the procedure. The system has been approved by the U.S. Food and Drug Administration (FDA).
