Cadaveric model. 研究设计:尸体模型。,ABSTRACT,Objectives. To compare the effect of PEEK versus conventional implants on scatter radiation to a simulated tumor bed in the spine 目的:比较PEEK与传统植入物对脊柱模拟放射治疗的影响,ABSTRACT,Summary of Background Data. Given the highly vasculature nature of the spine, it is the most common place for bony metastases. After surgical treatment of a spinal metastasis, adjuvant radiation therapy is typically administered. Radiation dosing is primarily limited by toxicity to the spinal cord. The scatter effect caused by metallic implants decreases the accuracy of dosing and can unintentionally increase the effective dose seen by the spinal cord. This represents a dose-limiting factor for therapeutic radiation postoperatively. 背景资料概述:由于椎体的血运丰富,所以是骨转移最常发生的部位。脊柱转移癌的外科治疗后,通常需要辅助放射治疗。辐射剂量主要受脊髓毒性的限制。金属植入物引起的散射效应降低剂量的准确性,并可以无意中增加脊髓的有效剂量。这代表术后放射治疗的剂量限制因素。,ABSTRACT,Methods. A cadaveric thorax specimen was utilized as a metastatic tumor model with two separate three-level spine constructs (one upper thoracic and one lower thoracic). Each construct was examined independently. All four groups compared included identical posterior instrumentation. The anterior constructs consisted of either: an anterior polyether ether ketone (PEEK) cage, an anterior titanium cage, an anterior bone cement cage (polymethyl methacrylate), or a control group with posterior instrumentation alone. Each construct had six thermoluminescent detectors to measure the radiation dose. 方法:使用尸体胸部标本作为具有两个完整脊柱三柱构造(一个上胸椎和一个下胸椎)的转移性肿瘤模型。独立地检测每个构建体。所有四组比较包括相同的后路内固定物。前柱固定使用:前聚醚醚酮(PEEK),钛笼,骨水泥笼(聚甲基丙烯酸甲酯)或仅有后路内固定的对照组。每个构建体用六个热释光检测器以测量辐射剂量。,ABSTRACT,Results. The mean dose was similar across all constructs and locations. There was more variability in the upper thoracic spine irrespective of the construct type. The PEEK construct had a more uniform dose distribution with a standard deviation of 9.76. The standard deviation of the others constructs was 14.26 for the control group, 19.31 for the titanium cage, and 21.57 for the cement (polymethyl methacrylate) construct. 结果:所有构建体和位置的平均剂量相似。无论内固定类型如何,上胸椎存在更多的变异性。 PEEK构建体具有更均匀的剂量分布,标准偏差为9.76。其他构建体的标准偏差:对照组为14.26,钛笼为19.31,骨水泥(聚甲基丙烯酸甲酯)构建体为21.57。,
