Analysis of clinical effect of operative treatment for grade IV pronation-external rotation ankle injury

Abstract

Objective To explore the clinical effect of operative treatment for grade Ⅳ pronation-external rotation ankle injury. Methods 60 patients with pronation extorsion type Ⅳ degree of ankle injury were selected as the research subjects.According to the digital table, they were divided into two groups, 30 cases in each group.The group A adopted ordinary steel plate, the group B adopted locking plate fixation.The clinical curative effect, postoperative recovery index, AOFAS score and complications were observed. Results The total effective rate of group A was 93.3%, which of group B was 90.0%, the difference was not statistically significant(χ2=0.218, P>0.05). The swelling subsided time[(24.2±5.0)d vs.(22.9±4.1)d], fracture healing time[(42.4±9.5)d vs.(41.3±9.4)d], postoperative recovery time of walking[(46.6±9.2)d vs.(45.7±9.0)d], AOFAS score[(87.3±2.6) vs.(88.4±2.2)] between the two groups had no statistically significant differences(t=1.101, 0.451, 0.383, 1.769, all P>0.05). The group A had 1 case in infection, the incidence rate of complications was 3.3%.The group B had no complication.The difference was not statistically significant in the incidence of complications between the two groups(χ2=1.017, P>0.05). Conclusion In the operative treatment for patients with grade Ⅳ pronation-external rotation ankle injury, whether choose ordinary steel plate fixation, or choose the locking plate fixation, the clinical effects of the two methods are both good, and the postoperative healing is fast.
