Popis: Abstract Purpose To evaluate if the size of Humeral Hill‐Sachs Defects (HSDs) increases during reduction in the emergency department (ED) in subjects that have a first‐time anterior shoulder dislocation. Methods Subjects more than 18 years old presenting to the ED a first‐time anterior shoulder dislocation were included. A computed tomography was performed prior to any reduction attempt (Pre‐CT). The shoulder was reduced in the emergency room with intraarticular lidocaine; if two attempts failed, the shoulder was reduced under anaesthesia. A second CT was performed after reduction of the shoulder (Post‐CT). CT were evaluated using the Osirix software. A 3‐dimensional reconstruction of the humeral head was performed and the maximum width of the humeral defect, maximum depth of the humeral defect and total volume of the humeral defect were measured. The relative increase in size was calculated. Results Twenty subjects were included in the study. All subjects presented HSDs in the Pre‐CT that had a width of a median of 9.9(interquartile range:2.9)mm, a depth of 7.0(3.0]mm and a volume of 355(333)mm2. The HSD in the Post‐CT had a width of 10.9(3.0)mm (an increase of 7.23[8.5]%, significant differences, p = 0.0001) a depth of 7.2(2.7)mm (an increase of 9.93[20.7]%, significant differences, p
