Abstract:
Objective:To investigate the effects of area of the posterior malleolus fracture and injury to the distal tibiofibular syndesmosis on functional recovery of the ankle joint in Bartoní?ek type 2 ankle fractures.Methods:A retrospective analysis was conducted of the clinical data of 47 patients with Bartoní?ek type 2 ankle fracture who had been treated at Department of Orthopedics, Huashan Hospital Affiliated to Fudan University from January 2016 to January 2022. There were 22 males and 25 females with an age of (46.0±15.6) years. All patients were treated by open reduction and closed reduction. Pearson correlation analysis and multiple regression analysis were used to investigate the relationships respectively between the American Association of Foot and Ankle Surgeons (AOFAS) ankle-hindfoot scores at the last follow-up and the preoperative proportion of posterior ankle fracture area, and the anterior and posterior tibiofibular distances.Results:All patients were followed up for (17.2±0.6) months after surgery. The Pearson correlation analysis showed that the proportion of posterior ankle fracture area ( P=0.160) and the posterior tibiofibular distance ( P=0.078) were significantly correlated with the AOFAS ankle-hindfoot score at the last follow-up. There was no significant correlation between the anterior tibiofibular distance and the AOFAS ankle-hindfoot score at the last follow-up ( P=0.689). The multiple regression analysis showed that the proportion of posterior ankle fracture area ( P=0.043) and the posterior tibiofibular distance ( P=0.022) had significant negative effects on the AOFAS ankle-hindfoot score at the last follow-up. Conclusions:In Bartoní?ek type 2 ankle fractures, the proportion of posterior ankle fracture area and the posterior tibiofibular distance are important predictors for postoperative functional recovery of the ankle. Therefore, in Bartoní?ek type 2 ankle fractures, surgical indications for the posterior malleolar fracture depend not only on the size of the fracture, but also on whether the fracture involves the lower tibiofibular syndesmosis.
