Medial pivot dislocation of talonavicular joint- A rare injury with literature review

Abstract

Medial pivot dislocations are dislocation of talonavicular joint (TNJ) medially with calcaneum subluxate beneath the talus with intact calcaneocuboid joint and interosseous ligament. These dislocations have subtle incidence and are mostly related to high energy injuries. These dislocations are easy to reduce having good functional outcome if diagnosed early. We presented two cases of young active patients who sustained injury to their foot after fall from height and road traffic accident. There were diffuse swelling and tenderness over the foot. X-ray showed medial dislocation of TNJ. Closed reduction was done in both patients. One patient needs percutaneous K-wire fixation. At one year follow-up, foot was painless, stable with normal ankle and subtalar motion.
