Fluoroscopic Exposure With Use of Mini-C-Arm During Routine Hand Surgery: A Prospective Comparison of Hand Versus Eye Radiation Dosage

Radiation exposure with use of intraoperative fluoroscopy is a potential orthopedic occupational risk factor. The purpose of this study was to perform a prospective comparison of hand versus eye radiation exposure associated with mini-C-arm utilization and to test the hypothesis that routine mini-C-arm does not yield hand or eye dosages exceeding current recommended levels. Over a 12-month period, hand and eye radiation exposure was prospectively measured in a single board-certified hand surgeon using mini-C-arm fluoroscopy. Twenty-five cases were performed utilizing mini-C-arm fluoroscopy. Average monthly hand radiation dosage (45.81±14.49 mrem) was significantly higher (p = .01) than eye radiation dosage ( Key words: cataracts, eye radiation, fluoroscopy, hand radiation, mini-C-arm, radiation exposure
