AbstractIrreducible ankle fracture-dislocations are rare. Several cases of irreducible ankle fracture-dislocation have been reported in published studies secondary to the tibialis posterior tendon, deltoid ligament, or extensor digitorum longus tendon blocking the reduction. We report a case of irreducible ankle fracture-dislocation resulting from posteromedial subluxation of the tibialis anterior tendon around a medial malleolar fracture fragment. Ultimately, the ankle required open reduction of the incarcerated tendon to reduce the joint and proceed with internal fixation of the associated fracture. The patient's postoperative course was uncomplicated, and the tibialis anterior tendon was functioning at 10 months postoperatively, after which he did not return for follow-up examinations. To our knowledge, this is the first reported case of the tibialis anterior tendon blocking closed reduction of an ankle fracture-dislocation.Copyright © 2015 American College of Foot and Ankle Surgeons.
