Plain posteroanterior and lateral radiographs of 456 patients with an acute fracture of the distal radius were classified by a consultant orthopaedic hand specialist and two specialist trainees, and the k coefficient for the inter- and intra-observer reliability of the type, group and subgroup classification was calculated. <\/jats:p><jats:p> Only the type of fracture (A, B or C) was found to provide substantial intra-observer reliability (k <jats:sub>type<\/jats:sub> 0.65). The inclusion of \u2018group\u2019 and \u2018subgroup\u2019 into the classification reduced the inter-observer reliability to fair (k<jats:sub>group<\/jats:sub> 0.29, k<jats:sub>subgroup <\/jats:sub>= 0.28) and the intra-observer reliability to moderate (k<jats:sub>group<\/jats:sub> 0.53, k<jats:sub>subgroup<\/jats:sub> 0.49). Disagreement was found to arise between specific subgroups, which may be amenable to clarification. <\/jats:p><jats:p> Cite this article: Bone Joint J 2015; 97-B:818\u201323. <\/jats:p>","DOI":"10.1302\/0301-620x.97b6.33844","type":"journal-article","created":{"date-parts":[[2015,6,1]],"date-time":"2015-06-01T11:05:00Z","timestamp":1433156700000},"page":"818-823","update-policy":"https:\/\/doi.org\/10.1302\/crossmark-policy","source":"Crossref","is-referenced-by-count":34,"title":["Is it time to revisit the AO classification of fractures of the distal radius?"],"prefix":"10.1302","volume":"97-B","author":[{"given":"C.
