Preoperative computed tomography showed an anterolateral tibial (Chaput) fragment entrapped within the distal syndesmosis, preventing adequate reduction. An open reduction of the fragment was performed in the operating room, which allowed near-anatomic reduction and internal fixation of the tibiotalar joint. At the 21-month follow-up visit, the patient remained on active duty in the Navy without limitations.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>To our knowledge, this rare injury pattern, an interposed Chaput fragment preventing closed reduction of the syndesmosis in a skeletally mature patient, has not previously been described in the literature.
