Medial swivel dislocation of talonavicular joint: a case report and literature review.

Midtarsal dislocations of the foot are rare injuries. Most descriptions of these injuries state that they develop due to high-energy trauma. We present a case of low-energy trauma leading to a medial swivel dislocation of the talonavicular joint, which was reduced by a closed method and immobilized in a cast. A 48-year-old non-diabetic male with no rheumatoid symptoms or any steroid injection suffered low-energy trauma to his right foot and presented to the emergency department with pain, tenderness and with his foot adducted. On X-rays and NCCT, it was found to be medial type swivel dislocation of the Talonavicular joint with a fractured base of the fifth metatarsal and talar head impaction fracture with talocalcaneal joint subluxation. Closed reduction under sedation was done successfully, which was stable on stressing under fluoroscopy, so the foot was immobilized in a cast without internal fixation. Talonavicular dislocations are rare injuries, with most of them requiring open reduction and internal fixation. Low-energy trauma can also lead to talonavicular dislocations, which, if stable after reduction, can be immobilized in a cast without internal fixation.
