The objective of this study was to directly measure the radiation exposure to the orthopaedic surgeon and to measure dose points to the surgeon's fingers, thyroid gland, and forehead during intraoperative fluoroscopy in periacetabular osteotomy (PAO). In a series of 23 consecutive periacetabular osteotomy procedures, exposure monitoring was carried out using thermo luminescent dosimeters. The effective dose received by the operating surgeon was 0.008 mSv per operation which adds up to a yearly dose of 0.64 mSv from PAO. The median point equivalent dose (mSv) exposure under PAO was 0.009 for the forehead and thyroid gland, 0.045 for the right index finger, and 0.039 for the left index finger. The effective estimated yearly dose received by the operating surgeon was very low. Wearing a lead collar reduces radiation exposure to the thyroid gland while the lead gloves did not protect the surgeon's fingers.
本研究的目的是直接测量髋关节周围截骨术（PAO）术中透视时骨科医生的辐射暴露量，并测量医生手指、甲状腺和额头的剂量点。在一系列 23 例连续的髋关节周围截骨术中，使用热释光剂量计进行了接触监测。手术医生接受的有效剂量为每次手术 0.008 毫希，每年接受的 PAO 剂量总计为 0.64 毫希。PAO 下额部和甲状腺的中点等效剂量（mSv）暴露中位数分别为 0.009 和 0.009，右食指为 0.045，左食指为 0.039。手术医生接受的有效估计年剂量非常低。佩戴铅领可减少甲状腺的辐射暴露，而铅手套并不能保护医生的手指。
