Study showed low patient, surgeon radiation exposure during direct anterior approach THA
Total patient and surgeon radiation exposure during direct anterior approach total hip arthroplasty was low, but increased as patient BMI increased, according to results.
Researchers performed a retrospective chart review of 157 patients who underwent direct anterior approach total hip arthroplasty (THA) between 2012 and 2014. Of these, 117 cases were included in the analysis. Researchers collected exposure time, radiation emittance and peak kilovoltage (kVp) from patients’ electronic medical records.
Results showed an average absorbed dose of radiation of approximately 2.97 milligray, with an average exposure time per procedure of 23.74 seconds. To create the image, researchers found an average amount of maximum energy of 75.38 kVp was used. Although kVp and BMI had a significantly strong correlation, researchers noted a positive but weak linear relationship with radiation dose and BMI and a weak correlation between fluoroscopy time and BMI. – by Casey Tingle
