The aim of this study is to clarify the natural course of Rockwood grade 3 acute acromioclavicular dislocation without medications.19 patients who had been diagnosed Rockwood grade 3 acute acromioclavicular dislocation at Yamagata Saisei Hospital from 1998 to 2007, and had also been followed without medications were investigated. They were all men, whose average age at injury was 32.4 years(range, 16 to 67 years). The mean follow-up period was 5.8 years(range, 2 to 9 years). We evaluated pain, limitation of motion, click, appearance, weakness, sensory disturbance, sport activity and satisfaction. The pain, limitation of motion and satisfaction were evaluated with visual analogue scale(VAS: range, 0 to 100). The average point of pain was 7.3(range, 0 to 23), ten cases were 0 points. The average point of limitation of motion was 12.4(range, 0 to 35), nine cases were 0 points. Click existed in 8 cases. Severe float were in seven cases, mild float were in 12 cases. Only one case had weakness, sensory disturbance and discomfort of throwing activity. The average satisfaction was 91.5(range, 84 to 100), seven cases were 100 points.The natural course of Rockwood grade 3 acute acromioclavicular dislocation without medications had a satisfactory outcome, except for appearance.
