Ban I, Kristensen MT, Barfod KW, et al. - This study was intended to correlate the functionality of adults with displaced mid-shaft clavicular fractures treated either operatively or nonoperatively and to compare the relative risk of nonunion and reoperation between the two groups. Researchers included a total of 120 adults (median age 37.5 years (interquartile range (18 to 61)) and 84% males (n = 101)) diagnosed with an acute displaced mid-shaft fracture, and randomized them to either the operative (n = 60) or nonoperative (n = 60) treatment group. They evaluated functionality by the Constant score (assessor blinded to treatment) and Disability of the Arm, Shoulder, and Hand score. It was shown that superiority was not identified with either an all-operative or all-nonoperative approach. The data indicated that functionality in short term (within six weeks) likes greater following operative treatment but was not found at one year. The results indicated that the risk of nonunion is significantly higher with nonoperative treatment. Nevertheless, it has been considered that an all-operative approach to lower the nonunion risk may result in unnecessary surgery and is not recommended.
