Abstract：Objective To explore the effect of open reduction combined with universal locking plate on the functional recovery and safety of elderly patients with acute foot lisfranc injury. Methods A total of 76 elderly patients with acute foot lisfranc injury admitted to 363 Hospital of General Medical from March 2018 to April 2020 were selected. The patients were divided into ordinary plate group (open reduction + ordinary plate) and universal locking plate group (open reduction + universal locking plate) by random number table method, 38 patients in each group. Operation time, intraoperative blood loss, total weight-bearing time were compared between the two groups. Visual analogue scale (VAS) scores were compared between the two groups before operation and one, three, and six months after operation, and American Orthopaedic Foot & Ankle Society (AOFAS) ankle hindfoot scale scores were compared between the two groups at three, six, and 12 months after operation. The incidence of postoperative complications was compared between the two groups. Results There were no significant differences in operative time, intraoperative blood loss, and complete weight-bearing time between the two groups (P ＞ 0.05). VAS scores at one, three, and six months after operation in both groups were lower than those before operation, VAS scores at three and six months after operation in both groups were lower than those at one month after operation, and VAS scores at six months after operation in both groups were lower than those at three months after operation (P ＜ 0.05). AOFAS ankle hindfoot scale scores of the two groups at six and 12 months after operation were higher than those at three months after operation, AOFAS ankle hindfoot scale scores of the two groups at 12 months after operation were higher than those at six months after operation, and AOFAS ankle hindfoot scale score of the universal locking plate group at 12 months after operation was higher than that of the ordinary plate group at the same time point (P ＜ 0.05). The total incidence of postoperative complications in the universal locking plate group was lower than that of the ordinary plate group (P ＜ 0.05). Conclusion Open reduction combined with universal locking plate is beneficial to the functional recovery of elderly patients with acute lisfranc injury, reducing the incidence of complications, and further promoting clinical practice.
