Duplicate publication in the Journal of Hand Surgery.

This study evaluates the extent of duplicate publication in the Hand Surgery literature. A retrospective review of original articles published in the American and the British & European editions of Journal of Hand Surgery during the years 1999 and 2000 was performed using MEDLINE (PUBMED) search engine. Index articles suspected of dual publication were identified by using key words in the title and the names of the first, second and last authors. The full initial text was carefully studied and suspected duplicate articles were classified as dual, potentially dual or fragmented. Six hundred articles were evaluated, of which 25 (4%) index articles were identified with 33 "suspects". Eleven "index" and 15 "suspected" articles were cleared on closer scrutiny. Thus 14 "index" articles (2%) were found to be associated with 18 duplicated articles. Of these, four were classified as dual, five as potentially dual and nine as fragmented. We conclude that although duplicate publication of articles in the Journals of Hand Surgery (American and British/European Volumes) does occur, the incidence in the sample studied is lower than some other surgical journals.
