Failure to achieve stable fixation during surgery for a Lisfranc joint injury leads to subtle instability that causes dysfunction and posttrau?matic osteoarthritis. Therefore, it is important to check for appropriate fixation during surgery. This paper reports a test that evaluates the joint instability dynamically during the open reduction of the Lisfranc joint and checks the stability after fixation. a Freer elevator was inserted into the interosseous area between the medial cuneiform and second metatarsal base, and a twisting force was applied to evaluate the dynamic instability of the Lisfranc joint. After fixation of the Lisfranc joint, the stability of the fixation could be tested by trying this maneuver with the Freer elevator. Overall, the Freer test can be considered a valuable test in open surgery for a Lisfranc joint injury.
