Within the scope of the SNF Project for the study of the instability of the distal radioulnar joint of the forearm (DRUJ), we conducted different experiments to record the anatomical changes in the pro-supination motion of the forearm, while subsequently resecting the surrounding soft tissue. The structures of interest were the interosseous membrane, the TFCC complex and the distal and proximal forearm joints. This dataset is divided into 5 different folders, corresponding to 5 different cadaveric forearms. The motion movement for each forearm was passively generated by a custom-made device, and the motion was recorded using 4 different IR markers and the Atracsys motion system. The protocol of the experiments as well as the recorded motion data are provided, together with the 3D models of each forearm.
