The corresponding author, Dr. Atul Bhaskar, submitted this article [1] to Journal of Children’s Orthopaedics (JCOR) and shortly after [2] to Indian Journal of Orthopaedics (IJO). JCOR published it in October 2009, and in October–December 2009 the article was published in IJO. Since there are significant similarities between the two papers, it has been brought to the attention of the author that duplicate submission and publication have taken place. The editors of JCOR who act according to the COPE Code of Conduct, consider this an infringement of professional ethics and therefore the decision has been made to retract the article published in Journal of Children’s Orthopaedics.
