Modern orthopaedic trauma practice involves increased exposure of the surgeon to ionising radiation. However, there have been no studies to investigate whether the doses received are within limits for non-classified workers. In this study, whole body, eye and extremity, namely hand, doses were measured in six orthopaedic surgeons during trauma cases requiring the use of X-rays in theatre. None of the subjects approached the recommended maximum dose levels for either the whole body, eyes or hands. This finding is reassuring. In orthopaedics, the limiting dose is that to the hands. This differs from previously studied groups, such as radiologists and cardiologists, in whom the limiting factor is the dose to the lens of the eye. Although current precautions appear to be adequate, safe practice in the future will depend on continuing vigilance and repetition of studies similar to this one as techniques and workloads change.
现代骨科创伤治疗使得外科医生更多地暴露于电离辐射中。然而，尚无研究调查所接受的剂量是否在非分类工作人员的限值范围内。在本研究中，对六名骨科外科医生在手术室进行需要使用X射线的创伤病例时的全身、眼睛及四肢（即手部）剂量进行了测量。没有一名受试者接近全身、眼睛或手部推荐的最大剂量水平。这一发现令人安心。在骨科领域，限制剂量是针对手部的。这与之前研究的群体（如放射科医生和心脏病专家）不同，在这些群体中，限制因素是晶状体所接受的剂量。尽管目前的预防措施似乎足够，但未来的安全操作将取决于随着技术和工作量的变化持续保持警惕并重复进行类似本研究的调查。
