It is important to counsel patients regarding these devastating injuries and their poor prognosis, as osteonecrosis, subtalar and tibiotalar joint degeneration, and talar collapse are not infrequent. In a series by Lindvall et al, subtalar joint arthritis was reported as more common than osteonecrosis of the talus at 4 year follow-up after fixation. Osteonecrosis of the talus was the next most common complication following surgery. The referenced article by Vallier et al reported on mid- to long-term follow-up of this patient population. Ten of the twenty-six patients had development of osteonecrosis of the talar body, but only half experienced collapse of the talar dome. All patients with a history of both an open fracture and osteonecrosis experienced collapse. Seventeen of twenty-six patients had posttraumatic arthritis of the tibiotalar joint, and nine of twenty-six had posttraumatic arthritis of the subtalar joint. Illustrations A and B show a displaced talar neck fracture.
