Exposure to ionizing radiation in the operating room is governed by practical prevention and protection measures on the international, national and local levels. We evaluated the equivalent dose to the hand of an orthopedic surgeon over 13 months. An orthopedic surgeon wore a ring dosimeter on the ring finger of his right hand for all surgical procedures requiring intraoperative fluoroscopy between March 2014 and April 2015. Monthly doses were evaluated by the IRSN over the study period. The number and type of procedures were compiled as well as the type of fluoroscopy unit used. Four hundred procedures were performed during this period, including 182 with fluoroscopy. The equivalent cumulative dose at the hand was 4,75 mSv. No correlation was found with the type of procedure or type of fluoroscopy unit (conventional or mini C-arm). Equivalent doses were below the annual regulatory limit in France of 500 mSv. These results are consistent with those reported in the literature. However, recent studies have noted that both younger surgeons in training and more experienced surgeons must remember to use radiation protection measures.
手术室中电离辐射的暴露受国际、国家和地方层面的实际预防与保护措施管控。我们评估了一名骨科医生在13个月期间手部的当量剂量。一名骨科医生在2014年3月至2015年4月期间，对于所有需要术中透视的外科手术，都在右手无名指佩戴了指环剂量仪。在研究期间，法国国家辐射防护与核安全研究所（IRSN）对每月剂量进行了评估。同时记录了手术的数量和类型以及所使用的透视设备类型。在此期间共进行了400例手术，其中182例使用了透视。手部的当量累积剂量为4.75毫希沃特。未发现与手术类型或透视设备类型（传统型或微型C型臂）存在相关性。当量剂量低于法国每年500毫希沃特的监管限值。这些结果与文献报道一致。然而，最近的研究指出，无论是年轻的实习外科医生还是经验更丰富的外科医生都必须牢记采取辐射防护措施。
