Analysis of the relevant factors for ischemic necrosis of the talus fracture / 中国骨伤

ABSTRACT

<p><b>OBJECTIVE</b>To explore the relationship of the classification of talus fracture and surgery methods with avascular necrosis.</p><p><b>METHODS</b>From March 2009 to November 2013, 78 patients with talus fracture were treated, of them, 43 cases were followed up from 2 to 5 years. There were 27 males and 16 females, aged from 17 to 65 years old with the mean of 38.6 years. Thirty-nine cases had talar neck injury and 4 cases had talar body injury. Different treatments were performed according to different injury conditions. The time from injury to treatment was from 6 to 48 hours. The effect of classification of talus fracture and surgery methods on avascular necrosis was analyzed.</p><p><b>RESULTS</b>In 43 cases,19 cases occurred avascular necrosis, including talar neck fracture of type I in 2 cases, type II in 5 cases, type III in 5 cases, type IV in 5 cases and talar body fracture in 2 cases (combined with talar neck fracture). And 29 patients were treated with operation, there was no statistically significant differences in avascular necrosis with different operations.</p><p><b>CONCLUSION</b>Compared with talar body fracture, talar neck fracture is more easily to develop into avascular necrosis. In the 4 types of talar neck fracture, the possibilities of type III and IV were the most ones.</p>
