This study intends to measure the radiation dose to patients and staff during (i) Dynamic Hip Screw (DHS) and (ii) Dynamic Cannula Screw (DCS) and to evaluate entrance surface Air kerma (ESAK) dose and organ doses and effective doses. Calibrated Thermoluminescence dosimeters (TLD-GR200A) were used. The mean patients' doses were 0.46mGy and 0.07mGy for DHS and DCS procedures, respectively. The mean staff doses at the thyroid and chest were 4.69mGy and 1.21mGy per procedure. The mean organ and effective dose for patients and staff were higher in DHS compared to DCS. Orthopedic surgeons were exposed to unnecessary radiation doses due to the lack of protection measures. The radiation dose per hip procedure is within the safety limit and less than the previous studies.
本研究旨在测量患者和工作人员在（i）动力髋螺钉（DHS）和（ii）动力套管螺钉（DCS）手术过程中的辐射剂量，并评估体表空气比释动能（ESAK）剂量、器官剂量和有效剂量。使用了校准后的热释光剂量计（TLD-GR200A）。DHS和DCS手术患者的平均剂量分别为0.46mGy和0.07mGy。每次手术时甲状腺和胸部工作人员的平均剂量分别为4.69mGy和1.21mGy。与DCS相比，DHS中患者和工作人员的平均器官剂量和有效剂量更高。由于缺乏防护措施，骨科外科医生受到了不必要的辐射剂量。每次髋关节手术的辐射剂量在安全限值内，且低于先前的研究。
