Key result
The calculated mean annual occupational radiation dosage for orthopaedic theatre staff was 0.977 mSv, which is significantly below the international reference threshold of 20 mSv (p=0.000).
Why the study?
Does C-arm fluoroscopy during orthopaedic surgeries result in occupational radiation doses exceeding accepted reference standards for theatre staff?

ORD data from 50 fluoroscopy cases offer baseline estimates; leaves open whether exposures routinely exceed standards in routine orthopaedic practice.
Observational (n=400)
Yes
Does C-arm fluoroscopy during orthopaedic surgeries result in occupational radiation doses exceeding accepted reference standards for theatre staff?
Absolute Event Rate: 0.977% vs 20%
p-value: p=0.000
Occupational radiation exposure for theatre staff during common orthopaedic surgeries using C-arm fluoroscopy is well below the accepted annual safety thresholds.
Liyanage et al. (2022) conducted an observational in Occupational radiation exposure (n=400). C-arm fluoroscopy during orthopaedic surgeries vs. International recommended dose level (20 mSv/year) was evaluated on Extrapolated annual mean occupational radiation dose (p=0.000). The calculated mean annual occupational radiation dosage for orthopaedic theatre staff was 0.977 mSv, which is significantly below the international reference threshold of 20 mSv (p=0.000).
