Background: This study aimed to apply meta-analysis to study the efficacy of surgical repair treatment on ankle fractures. Methods:The Boolean logic search method was adopted to retrieve relevant randomized control trials (RCTs), with "Fracture", "Ankles", "Fractured Foot", "Fractures Merge", and "Surgical Treatment" as search terms. The databases PubMed, Medline, HowNet, and others were searched from the time of their establishment. The software Review Manager (Rev Man 5.3) was used for meta-analysis.Results: A total of 10 references were included in the study, and most of them had low-risk bias (mediumhigh quality). The results of meta-analysis showed that after surgical repair treatment, gait was good, while the gait score of the non-surgical group was poor. The result was Chi 2 (Chi-squared Test) =57.91, df (degree of freedom) =5, I 2 =91%, P<0.1, mean difference (MD) =−9.21, 95% CI: −10.25 to −8.17, Z=17.36, P<0.05.The non-surgical group showed a higher degree of pain and poorer ankle and hindfoot functions vs. the surgical group. Also, the pain degree of the non-surgical repair combined with surrounding tissue group was higher, and the ankle and hindfoot functions were poorer vs. the surgical repair treatment group. The Pain intensity results of the surgical and non-surgical groups were Chi 2 =12.89, df =2, I 2 =84%, P <0.1, MD

Background: Treatment of exposed steel plates after surgery for foot and ankle fractures is complicated.This study aims to analyze the effects of microsurgical repair treatment on the clinical efficacy, complications, and flap follow-up scores of patients with exposed steel plates following foot and ankle fracture surgery.Methods: Eighty-two patients with exposure of steel plates after surgical treatment for foot and ankle fractures in our hospital from March 2017 to March 2018 were included in this study. The patients were divided into a study group (43 patients who received microsurgical repair) and a control group (39 patients who received conventional repair surgery). We compared the clinical efficacy, complication rate, flap followup score, recovery of ankle-hindfoot function and ankle function before treatment and at 3 and 6 months after treatment, and patient satisfaction between the two groups.Results: The clinical effectiveness rate in the study group was 95.35%, which was higher than the control group (76.92%) (P<0.05). The flap appearance, texture, and elasticity scores in the study group were higher than those in the control group (P<0.05). After treatment, the American Orthopedic Foot and Ankle Society (AOFAS) score and Baird ankle score increased significantly in both groups, and reached a peak at 6 months after treatment. The peak scores of the study group were considerably higher than those of the control group at each period after treatment (P<0.05). The incidence of complications in the study group (6.98%) was lower than the control group (25.64%) (P<0.05). Patient satisfaction was higher in the study group (97.67%) than the control group (79.49%) (P<0.05).Conclusions: Microsurgical repair of exposed steel plates after surgery for foot and ankle fractures has a significant clinical effect. It can improve the flap follow-up scores, accelerate healing of the ankle, improve aesthetics, and reduce the incidence of complications. It is therefore worthy of widespread use in clinics.
