Osteochondral fracture is an attached fragment of subchondral bone become partially or completely separated from the underlying bone. Accurate diagnosis of osteochondral fracture of the talus,mainly caused by trauma, is difficult because osteochondral lesion is not detected easily on the roentgenographic examination. Osteochondal fracture is intraarticular fracture, thus operative approach and fixation is technically difficult and requires talus, with subchondral bone curettage through percutaneous extraarticular transtalar approact under the C-arm guide without arthrotomy in three cases of minimally detached or elevated osteochondral fragment. And two cases of partially detached osteochondral fragment treated by bone peg fixation with arthrotomy. We obtained good functional results at the follow-up of a mean of 1 year and 5 months. We believe that the subchondral curettage and bone peg fixation are excellent treatment methods for osteochondral fracture of the talus.
