Asian Spine J 2016;10:65-9http://dx.doi.org/10.4184/asj.2016.10.1.65I am retracting our article "Sensitivity of Pyramidal Signs in Patients with Cervical Spondylotic Myelopathy" [1], because it was noted that several expressions of this article were identical to those of previously published paper without the proper citation "Eur Spine J 2010;19:1684-9" [2]. I deeply regret this plagiarism. I would like to express my most sincere apology to Prof. Chikuda and the European Spine Journal and to the Editor and readers of Asian Spine Journal.
