In plain language
In 51 direct anterior hip replacements by one surgeon, fluoroscopy time averaged under a minute and the surgeon's dosimeter recorded 10 mrem in total, suggesting low occupational exposure with a standard protocol in this setting.

What it found
The surgeon's cumulative dosimeter reading across all 51 procedures was very low.
Key figures: 10 mrem for all procedures combined
Median patient dose-area product per direct anterior total hip arthroplasty (THA) was low.
Key figures: median dose-area product (DAP) 0.716 Gy-cm(2) (range 0.251-1.81)
Mean fluoroscopy time per case was under one minute.
Key figures: 0.59 minutes
Dose and fluoroscopy time were comparable to published values for other fluoroscopically guided hip procedures.
Limits to keep in mind
Single surgeon at one centre with 51 cases following a set fluoroscopy protocol; only a single cumulative dosimeter reading for the surgeon, with no data on other OR staff, dosimeter location, or apron use.
