title: Reliability of the Robinson classification for displaced comminuted midshaft clavicular fractures.
abstract: This study aimed to assess the reliability of the Robinson classification for displaced comminuted midshaft fractures. A total of 102 surgeons and 52 radiologists classified 15 displaced comminuted midshaft clavicular fractures on anteroposterior (AP) and 30-degree caudocephalad radiographs twice. For both surgeons and radiologists, inter-observer and intra-observer agreement significantly improved after showing the 30-degree caudocephalad view in addition to the AP view. Radiologists had significantly higher inter- and intra-observer agreement than surgeons after judging both radiographs (κmultirater of 0.81 vs. 0.56; κintra-observer of 0.73 vs. 0.44). We advise to use two-plane radiography and to routinely incorporate the Robinson classification in the radiology reports.
