椎间盘蜕变后，椎间融合器可以用于帮助促进脊柱节段固定术后的恢复。当两节椎盘相互生长和融合时，医疗器械扮演着支撑前椎柱的角色。椎间融合术比椎间盘置换术应用更加广泛。
ASTM F2267-04 “测试在静态轴挤压下椎间体融合设备的负载导致下陷的试验方法”指定了一种可以在体外进行的静态轴挤压测试方法，以提供不同融合植入物之间的力学性能对比。这个测试的执行可以用金属块或者聚氨酯块为辅助材料。
这个测试可以在横梁上带有移动作动器的万能试验机中进行。但是，我们还是倾向于推荐以下两种系统： ElectroPuls E10000 拉扭双轴电子动静态万能测试系统和8876电液伺服测试系统。这两种系统允许专业夹具在温控浴中进行测试，这种温控浴可以稳定地模拟体内环境。我们的测试系统也允许在移动作动器的末端安装一个传感器用来精确测定下陷力的值。
