This study aimed to audit large quantities of mini C-arm data used in hand and wrist surgery and to analyse what effect the type and anatomical location of procedures had on screening time and dose area product. Of a total of 2032 procedures, the median screening time was 11 seconds and median dose area product was 0.75 cGycm. The third quartile value for screening time was 23 seconds and dose area product was 1.62 cGycm. The median screening time for closed procedures was 7 seconds and the dose area product was 0.57 cGycm. The median screening time for open surgery was 23 seconds with a median dose area product of 1.45 cGycm. The data for steroid injection procedures were similar to those of the closed procedures, with a median screening time of 7 seconds and dose area product of 0.45 cGycm. We found no significant differences in the screening time or dose area product between procedures on the wrist and forearm compared with the hand and digits. III.
本研究旨在审查大量在手外科和腕外科手术中使用的小型C形臂数据，并分析手术类型和解剖位置对筛查时间和剂量面积乘积有何影响。在总共2032例手术中，筛查时间的中位数为11秒，剂量面积乘积的中位数为0.75 cGycm。筛查时间的第三四分位数为23秒，剂量面积乘积为1.62 cGycm。闭合手术的筛查时间中位数为7秒，剂量面积乘积为0.57 cGycm。开放手术的筛查时间中位数为23秒，剂量面积乘积中位数为1.45 cGycm。类固醇注射手术的数据与闭合手术相似，筛查时间中位数为7秒，剂量面积乘积为0.45 cGycm。我们发现，与手部和手指手术相比，手腕和前臂手术的筛查时间或剂量面积乘积没有显著差异。 三、
