Radiation dose in assessment of tibial torsion with a mobile C-arm fluoroscope.
The absorbed dose to the skin was measured in adult patients undergoing fluoroscopy with a mobile C-arm fluoroscope for determination of tibial torsion. Two methods suitable for routine measurement of tibial torsion were investigated in this respect. The mean absorbed doses for assessment of torsion in one extremity were found to be 5.3 and 5.5 mGy respectively. No scattered radiation to the contralateral foot or symphysis of patient was recorded. The examiner received no measureable dose on any occasion.
