We undertook this study to determine the amount of scattered radiation received by the primary surgeon, assistant and patient during dynamic hip screw fixation for proximal femoral fractures. Data was collected from fifty patients. Five registrars were included as operating surgeon and four senior house officers as assistant surgeon. Radiation was monitored by thermo luminescent dosimeters placed on the surgeon and assistant. The approximate distance of surgeon and assistant from the operative site was measured. A dosimeter on the unaffected hip of patients measured the radiation to the patient. The results show that the surgeon's dominant hand receives the highest dose of radiation and radiation exposure is dependent on the experience of the operator. Our study concludes that exposure to radiation during this procedure is well below the toxic levels; however greater awareness is needed for harmful effects of exposure to long term low dose radiation.
我们开展这项研究，以确定在股骨近端骨折动力髋螺钉固定手术过程中主刀医生、助手及患者所接受的散射辐射量。数据收集自50例患者。5名住院医师作为主刀医生，4名高级住院医生作为助手。通过置于医生和助手身上的热释光剂量计监测辐射。测量了医生和助手与手术部位的大致距离。置于患者未受影响髋部的剂量计测量患者所接受的辐射。结果显示，主刀医生的优势手接受的辐射剂量最高，且辐射暴露取决于操作者的经验。我们的研究得出结论，在此手术过程中所受辐射远低于中毒水平；然而，对于长期低剂量辐射暴露的有害影响仍需提高认识。
