abstract: This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/our-business/policies/article-withdrawal).
  
  This article has been retracted at the request of the Corresponding Author, Yoshihiro Sato, and the co-authors have been informed.
  
  Dr. Sato wishes to retract this article on the grounds that it contains fabricated clinical trial data, which he was responsible for producing. In addition, Dr. Sato claims he listed all of the named co-authors without their consent. The co-authors were therefore unaware of the presence of fabricated data in this publication and their participation in the publication. This retraction was initiated by Dr. Sato, and the Editor-in-Chief of Bone was informed by the author directly.
