Analysis of clinical effect of operative treatment for grade Ⅳ pronation-external rotation ankle injury / 中国基层医药

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 (x2 =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 (x2 =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.
