To compare the radiation exposure of the primary surgeon while using the conventional c-arm and mini c-arm fluoroscopy at the shoulder Twelve shoulders of six fresh cadavers were used to simulate this experimental study. Radiation exposure of the primary surgeon was measured at the head and neck region. The average radiation dose was measured using both the conventional c-arm and mini c-arm, then the findings were compared. Mean radiation energy of the conventional c-arm was significantly lower than the mini c-arm at 59.39 ± 1.43 kV and 70.58 ± 4.01 kV respectively (p < 0.001). Dose rates to which the primary surgeon was exposed from the conventional c-arm and the mini c-arm were 81.46 ± 30.37 μSv/hour and 87.54 ± 43.69 μSv/hour, respectively. However, the difference was not statistically significant (p = 0.875). There is no difference in the level of radiation safety for the primary surgeon when using the conventional c-arm vs. the mini c-arm for a fluoroscopic-assisted shoulder procedure. Therefore, selection of the methodology should be based on equipment availability and clinical considerations.
