Abstract：Objective To investigate the characteristics of bony junction after distal tibiofibular fracture and its effect on ankle joint function. Methods The clinical data and imaging data of 74 patients with bony junction after distal tibiofibular fracture in Xuzhou Renci Hospital, Jiangsu Province from February 2014 to October 2018 were retrospectively analyzed. The imaging data and the incidence of complications were analyzed, and the range of motion of the affected and healthy ankles and the American orthopedic foot ankle society (AOFAS) score were compared at the last follow-up. Results Among the 53 distal tibiofibular fractures involving the ankle joint, 48 cases had bony junction at the tibiofibular syndesmosis level. Eleven of the 14 cases of simple distal tibionfibular fractures had bony junction at the fracture line, two of the four cases of tibia shaft combined with lateral malleolus fractures had bony junction at the locking nail at the distal end of the tibial intramedullary needle, and three cases of Pilon fracture had bony junction at the fracture line. At the last follow-up, the range of motion of plantar flexion, active dorsal extension, passive dorsal extension and AOFAS score of the affected side were lower than those of the healthy side, with statistical significance (all P ＜ 0.05). Adverse reactions occurred in 14 patients, including displacement of the broken end of the screw, needle tract infection, reduced range of motion or signs of osteoarthritis in the ankle, post-exertion soreness on the affected side, and slight discomfort in walking up and down stairs. Conclusion The bony junction of distal tibiofibular fracture occurs mostly in the fracture line, and the range of motion of the affected side of the ankle is lower than that of the healthy side, but it does not affect the daily life and work.
