一種新型椎體替代(VBR)脊椎隔板移植物能夠提供最大多骨生長區(qū)域，同時能夠維持移植物的結構力量。

Crystal VBR脊椎隔板移植物是由Quantum Orthopedics(Carlsbad, CA, USA)公司制造的，具有優(yōu)越的移植窗口和較大的內部移植空腔，能夠進行最優(yōu)化操作。移植物能夠透過射線，具有射線密集標記，能夠精確定位和放置，具有7種高度角度0°-7°。除此之外，VBR移植物單一方向的背脊設計能夠防止移植物移動。Crystal隔板由Peek-Optima制作而成，這是一種生物兼容性質穩(wěn)定的多聚乙醚酮聚合體，這是由Invibio(Lancashire, UK)公司制造的。這套系統(tǒng)包括一個顏色標記系統(tǒng)，確保外科醫(yī)生能夠安全迅速地進行手術。這套系統(tǒng)已經(jīng)獲得了美國食品藥品管理局的批準。
 
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).
