- Abstract: Objective To investigate the efficacy of different approaches for screw internal fixation in the treatment of posterior ankle fractures in trimalleolar fracture,and the complications was analyzed.Methods A prospective study was conducted on 80 patients with Haraguchi type Ⅰ posterior ankle fracture who admitted to our hospital from May 2019 to October 2020,they were randomly divided into group A and group B according to a random number table method,with 40 cases in each group.Patients in group A were treated with percutaneous anterior to posterior screw internal fixation for posterior ankle fractures,while patients in group B were treated with percutaneous posterolateral approach limited exposure and reduction screw internal fixation for posterior ankle fractures.The surgical indicators,postoperative recovery,American Orthopaedic Foot and Ankle Society(AOFAS)score,ROM score of ankle joint at the last follow-up,postoperative evaluation,and postoperative complications of patients between the two groups were compared.Results There was no statistically significant difference in operation time,complete weight-bearing time,or fracture healing time of patients between the two groups(P>0.05),but the fluoroscopy times of patients in group A was less than that in group B,the intraoperative bleeding volume and fibular incision length were less/shorter than those in group B(P<0.05).The AOFAS scores of patients 6 months after surgery and at the last follow-up in both groups increased compared with those 3 months after surgery,and the AOFAS scores at the last follow-up were higher than those 6 months after surgery,the differences were statistically significant(P<0.05).The AOFAS scores of patients 6 months after surgery and at the last follow-up in group B were higher than those in group A(P<0.05).There was no statistically significant difference in ROM score of ankle joints(plantar flexion,valgus,varus,dorsiflexion)of patients between the two groups at the last follow-up(P>0.05).There was no statistically significant difference in poor screw position,degree of pain,walking condition,or squatting condition of patients between the two groups(P>0.05).However,the reduction quality of posterior ankle fractures of patients in group B was better than that in group A(Z=4.248,P<0.05).No complications such as loosening of internal fixation or loss of fracture reduction occurred in both groups.Conclusion Both percutaneous anterior to posterior screw internal fixation and percutaneous posterolateral approach limited exposure and reduction screw internal fixation have good efficacy for posterior ankle fractures in trimalleolar fracture,with high safty.The former has more fluoroscopy times and less intraoperative bleeding,while the latter is better in improving ankle joint function and fracture reduction.
