During interlocking intramedullary nailing of twenty-five femoral and five tibial fractures, the primary surgeon wore both a universal film badge on the collar of the lead apron and a thermoluminescent dosimeter ring on the dominant hand to quantify the radiation that he or she received. When distal interlocking was performed, the first ring was removed and a second ring was used so that a separate recording could be made for this portion of the procedure. At the conclusion of the study, all of the recorded doses of radiation were averaged. The average amount of radiation to the head and neck during the entire procedure was 7.0 millirems of deep exposure and 8.0 millirems of shallow exposure. The average dose of radiation to the dominant hand during insertion of the intramedullary nail and the proximal interlocking screw was 13.0 millirems, while the average amount during insertion of the distal interlocking nail was 12.0 millirems. Both of these averages are well within the government guidelines for allowable exposure to radiation during one-quarter (three months) of a year. Precautions that are to be observed during this procedure are recommended.
在对25例股骨骨折和5例胫骨骨折进行交锁髓内钉固定手术时，主刀医生在铅衣领口佩戴通用胶片徽章，并在惯用手上佩戴热释光剂量计戒指，以量化其接受的辐射量。进行远端交锁时，取下第一枚戒指，使用第二枚戒指，以便对该部分手术进行单独记录。研究结束时，将所有记录的辐射剂量进行平均。整个手术过程中，头部和颈部接受的平均辐射量为深部照射7.0毫雷姆，浅部照射8.0毫雷姆。插入髓内钉和近端交锁螺钉时，惯用手接受的平均辐射剂量为13.0毫雷姆，而插入远端交锁钉时的平均辐射量为12.0毫雷姆。这两个平均值均远低于政府规定的一年四分之一（三个月）内允许的辐射暴露量。建议在该手术过程中遵守相应的预防措施。
