A comparison radiograph of the contralateral healthy wrist and an educational training in the various SNAC stages may improve reliability. Our purposes were to evaluate the difference in the reliability: (1) between observers who rate SNAC wrists with and without a comparison radiograph; and (2) between observers who receive training prior to ratings and those who do not. Methods: In this cross-sectional survey study, 82 fully trained orthopedic or hand surgeons rated anteroposterior radiographs of 19 patient wrists following a scaphoid nonunion based on SNAC stages 0 to 4. Observers were randomized online in 4 groups: one group rated unilateral views without training, a second group unilateral views with training, a third group bilateral views without training, and a fourth group bilateral views with training. Training included a 1-page clarification of the SNAC stages. Interobserver agreement was calculated using kappa statistics. Results: There was no significant difference between agreement between observers who rated unilateral radiographs (\u03ba = 0.55) and who rated bilateral radiographs (\u03ba = 0.58) ( P = .14), nor between agreement between observers who received training (\u03ba = 0.59) and who did not (\u03ba = 0.54) ( P = .058). Conclusions: The use of an additional comparison view and\/or training does not seem to be clinically relevant in SNAC staging. There is room for improvement in the way we assess patients with SNAC wrists.<\/jats:p>","DOI":"10.1177\/1558944716677541","type":"journal-article","created":{"date-parts":[[2016,11,9]],"date-time":"2016-11-09T07:59:17Z","timestamp":1478678357000},"page":"439-445","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["Does a Comparison View Improve the Reliability of Staging Wrist Osteoarthritis?"],"prefix":"10.1177","volume":"12","author":[{"given":"Paul W.
