Medial peritalar dislocation.

In this paper, a case of closed medial subtalar dislocation and accompanying talar head fracture in a 22-year-old man which occurred while walking on a downhill road is reported. Closed reduction under general anesthesia was unsuccessful. The obstacle for closed reduction was determined at surgery for open reduction and internal fixation as buttonholing of the talar head through the extensor retinaculum. At the 26-month follow-up, he was pain-free in his daily activities.
