Abstract

Seventy-one fractures through the neck of the talus were clinically evaluated and classified on the basis of roentgenographic appearance. The follow-up interval averaged 12.7 years. Good or excellent results were achieved in 59 per cent of the fractures. Accurate anatomical reduction of displaced fractures, if necessary by open reduction and internal fixation, is recommended. Avascular necrosis of the talar body occurred in 52 per cent of the fractures (in two of thirteen non-displaced fractures, in half of the fractures with subluxation or dislocation of the subtalar joint, and in sixteen of nineteen fractures with complete dislocation of the body of the talus). Many patients with avascular necrosis treated conservatively had satisfactory results. The complications of avascular necrosis, malunion, subtalar arthritis, and infection required twenty-five secondary procedures. Triple arthrodesis, tibiocalcaneal fusion, and dorsal beak resection of the talar neck all resulted in a high percentage of satisfactory results, but talectomy did not.
