The use of fluoroscopy has enabled orthopedic surgeons to become technically more proficient. In addition, these surgical procedures tend to have less associated patient morbidity by decreasing operative time and minimizing the area of the operative field. The trade-off, however, may be an increased risk of radiation exposure to the surgeon on an annual or lifetime basis. The current study was designed to determine the amount of radiation received by the primary surgeon and the first assistant during selected surgical procedures involving the use of fluoroscopy. Five body sites exposed to radiation were monitored for dosage. The results of this study indicate that with appropriate usage, (1) radiation exposure from fluoroscopy is relatively low; (2) the surgeon's dominant hand receives the most exposure per case; and (3) proper maintenance and calibration of fluoroscopic machines are important factors in reducing exposure risks. Therefore, with proper precautions, the use of fluoroscopy in orthopedic procedures can remain a safe practice.
荧光透视检查的应用使骨科医生在技术上更加熟练。此外，这些外科手术往往通过减少手术时间和最小化手术区域，降低患者相关的发病率。然而，权衡之处可能是外科医生每年或一生接受辐射的风险增加。当前的研究旨在确定在涉及使用荧光透视检查的特定外科手术过程中主刀医生和第一助手所接受的辐射量。对五个受辐射的身体部位进行了剂量监测。这项研究的结果表明，通过适当使用，（1）荧光透视检查的辐射暴露相对较低；（2）每位患者中主刀医生的优势手接受的辐射最多；（3）荧光透视设备的正确维护和校准是降低暴露风险的重要因素。因此，采取适当的预防措施后，在骨科手术中使用荧光透视检查仍可安全进行。
