Does Radiation Exposure During Pediatric Supracondylar Humeral Fracture Surgery Change According to the C-arm Position? A Comparison of Two Different Techniques

We read with interest the publication by İğrek and colleagues [1]. It is a known fact that the amount of C-arm scatter radiation depends on the position of the x-ray source in relation to the image intensifier [2]. Scatter radiation is higher below the elbow/operating table if the radiation source is below the patient and higher above the patient if the radiation source is above the elbow/operating table [2]. Therefore, it was to be expected that İğrek et al. [1] measured increased scatter radiation to the surgeon's neck dosimeter when the image intensifier (II) was positioned below the table.
