MATERIAL AND METHOD
39 patients with pertrochanteric femur fracture (n = 32) or lower leg fracture (n = 7) were treated with closed intramedullary nailing. The related radiation exposure of the patients was calculated.
RESULTS
Osteosynthesis of pertrochanteric fractures took less fluoroscopic time than osteosynthesis of lower leg fractures. The effective dose was 14 mSv for nailing osteosynthesis of proximal pertrochanteric fractures and less than 0.1 mSv for osteosynthesis of distal lower leg fractures.
CONCLUSION
Radiation exposure of the patient due to intraoperative fluoroscopic imaging during osteosynthesis can be estimated based on the data given above. Intraoperative observations imply, consequent application of radiation protection by the orthopaedic surgeons may reduce intraoperative radiation exposure even more.
材料与方法
39例股骨转子间骨折患者（n = 32）或小腿骨折患者（n = 7）接受了闭合髓内钉固定治疗。计算了患者的相关辐射暴露量。
结果
股骨转子间骨折的接骨术所需透视时间比小腿骨折的接骨术少。近端股骨转子间骨折接骨术的有效剂量为14毫希沃特，而小腿远端骨折接骨术的有效剂量小于0.1毫希沃特。
结论
根据上述数据可估算接骨术中术中透视成像给患者带来的辐射暴露量。术中观察表明，骨科医生随后应用辐射防护措施可能会进一步减少术中辐射暴露。
