Abstract：Objective:To explore the relationship between the selection of internal fixation materials and postoperative functional recovery of ankle fracture and provide individualized fixation scheme for patients.Methods:According to the choice of internal fixation materials,100 patients with ankle fracture in the 988th Hospital of the Joint Service Support Force of the Chinese People's Liberation Army(Jiaozuo Hospital Area)from January 2021 to May 2024 were divided into steel plate group(34 cases),metal screw group(33 cases)and absorbable screw group(33 cases).The basic information of patients and postoperative ankle recovery were collected,including operation time,intraoperative blood loss and hospitalization time,foreign body reaction rate,AOFAS score,fracture healing time,complete load-bearing time and visual analogue scale(VAS).Results:Compared to other groups,there were longer operation time and hospitalization time,and larger intraoperative hemorrhagein in steel plate group,and the differences were statistically significant(P＜0.05).The operation time and intraoperative hemorrhagein in the metal screw group and absorbable screw group were compared,here was no significant difference(P＞0.05).AOFAS score of absorbable screw group was significantly higher than that of steel plate group and metal screw group,and the steel plate group was higher than that of metal screw group,and the differences were statistically significant(P＜0.05).The fracture healing time and complete load-bearing time were significantly lower than those of steel plate group and metal screw group,and steel plate group was shorter than metal screw group,and the differences were statistically significant(P＜0.05).The VAS score of absorbable screw group was lower than that of steel plate group and metal screw group,and the metal screw group was lower than that of steel plate group,and the differences were statistically significant(P＜0.05).The foreign body reaction of absorbable screw group was significantly shorter than that of steel plate group and metal screw group,and the differences were statistically significant(P＜0.05).Conclusion:Different internal fixation materials have obviously different prognosis effects on patients with ankle fracture.Although the foreign body reaction rate of absorbable screw fixation method is obviously higher,its perioperative indicators and joint function recovery are good.When using absorbable screws in clinical treatment,doctors should pay attention to rejection and take relevant preventive and therapeutic measures to further improve the prognosis of patients.
