It was with great interest that we read the article by Dy et al. entitled, Peripheral Triangular Fibrocartilage Complex Tears Cause H Instability: A Biomechanical Pilot Study . We congratulate the authors on this important study and its outcome; however, we have several questions. First, what method was used to transect the ligaments? Second, how was complete transection of the ligaments ensured [2, 3]? Finally, was an additional arthroscopy of the distal radioulnar joint  performed to confirm complete transection?
We believe these are important questions that need to be answered. Additionally, we would have liked to see arthroscopic images of the triangular fibrocartilage complex tear before and after transection of its attachment.
