Spine surgeons rarely consider metal allergies when placing hardware, as implants are thought to be inert.
A 32-year-old male presented with a skin rash attributed to the trace metal in his spinal fusion instrumentation. Patch testing revealed sensitivities to cobalt, manganese, and chromium. He underwent hardware removal and replacement with constructs of commercially pure titanium. His skin findings resolved at 2 weeks after surgery and were stable at 6 weeks.
Hypersensitivity to metal (i.e., metal allergy) should be considered before performing instrumented spinal fusions.
脊柱外科医生在植入硬件时很少考虑金属过敏问题，因为植入物被认为是惰性的。
一名32岁男性因脊柱融合器械中的微量金属出现皮疹。斑贴试验显示对钴、锰和铬敏感。他接受了硬件移除，并更换为商业纯钛构建物。术后2周皮肤症状消失，6周时保持稳定。
在进行器械辅助脊柱融合之前，应考虑对金属的超敏反应（即金属过敏）。
