Methods. Retrospective review of 53 consecutive patients treated with combined anterior and posterior spinal arthrodesis.
方法：回顾性分析53例前后路脊柱融合病人。
Conclusion: Raised serum chromium levels were detected in 37% of patients following instrumented spinal arthrodesis for correction of scoliosis.
结论：青少年脊柱侧凸患者使用内固定脊柱融合术后，部分患者(37%)可出现血清铬含量升高。
Clinical Relevance: These data may be used to study the effects of spinal arthrodesis and to further define the mechanical component of adjacent-segment degeneration.
临床意义：这些数据可用于研究脊柱融合术的作用并进一步确定临近节段退变的机制。
Summary of Background Data. The lumbosacral junction continues to be a difficult region to obtain a successful spinal arthrodesis and is one of the primary regions for construct failure.
腰骶连接处仍然是成功进行脊柱内固定的困难部位，并且是内固定失败的主要部位之一。
Since rigidity of the instrumentation construct is one of the very few factors that is surgeon controlled, this could influence the choice of instrumentation in revision spinal arthrodesis.
由于器械结构的刚度是外科医生控制的极少的几个因素之一，因此这就可能影响其的脊柱关节融合翻修术中的应用。
Methods: Thirty patients with adolescent idiopathic scoliosis undergoing posterior instrumented spinal arthrodesis using stainless steel implants between 1998 and 2002 were prospectively studied.
目的：判定青少年特发性脊柱侧凸患者使用不锈钢后方入路脊柱内固定器械后血清铬水平的预测因子。
