Fluoroscopic guidance is commonly utilized during direct anterior total hip arthroplasty (DA THA). The purpose of this study was to measure patient and surgeon exposure utilizing this technique. Fifty-one consecutive patients who underwent primary DA THA by a single surgeon were prospectively studied. Fluoroscopic guidance was utilized according to an established protocol. Dose-area product (DAP) (Gy-cm(2)) and fluoroscopy time were recorded for each case. Surgeon exposure was recorded by a dosimeter. The median DAP was 0.716 Gy-cm(2) (range 0.251-1.81). Mean fluoroscopy time was 0.59 minutes. Dosimeter results were 10 mrem for all procedures combined. DAP and fluoroscopy times were comparable to published values for other fluoroscopically guided hip procedures. This information may aid in setting reference dose levels for this procedure.
在直接前路全髋关节置换术（DA THA）中，通常会使用荧光透视引导。本研究的目的是测量使用该技术时患者和外科医生所受到的辐射剂量。对一位外科医生连续进行的51例初次DA THA患者进行了前瞻性研究。荧光透视引导按照既定方案使用。记录每例患者的剂量面积乘积（DAP）（Gy-cm²）和透视时间。通过剂量计记录外科医生所受的辐射剂量。DAP中位数为0.716 Gy-cm²（范围0.251 - 1.81）。平均透视时间为0.59分钟。所有手术的剂量计结果总计为10毫雷姆。DAP和透视时间与其他荧光透视引导下髋关节手术的已发表值相当。这些信息可能有助于为该手术设定参考剂量水平。
