Objective To observe the efficacy of and influencing factors for kirschner wire limited internal fixation plus external fixation for patients with tarsometatarsal fracture dislocation. Methods The efficacy of kirschner wire limited internal fixation plus external fixation treatment for patients with tarsometatarsal fracture dislocation treated between January 2004 and June 2009 was retrospectively analyzed,and we also investigated the impact of surgery time and ligament damage on its long-term prognosis. Results Twenty patients were included,consisting of 16 male and 4 female patients,ranging from 15 to 57 years old.The mean time of follow-up was 24.5 months,ranging from 11 to 41 months.At the time of follow-up,there were 5%(1/20),10%(2/20),50%(10/20) and 35%(7/20) patients with AOFAS ankle-hindfoot score at 0~69,70~79,80~89 and 90-100,respectively;and the excellent rate was 85% in total.In this cohort,the acceptance rate of the results of treatment was 95% at discharging and 85% at the final follow-up,and the difference between the above two time-points was not statistically significant.In addition,patients with earlier surgery treatment and lower degree of ligament injury had better long-term prognosis. Conclusion For patients with tarsometatarsal fracture dislocation,treatment with kirschner wire limited internal fixation plus external fixation can not only effectively restore joint function,but also has minimum surgical trauma,and it is an effective method for the treatment of tarsometatarsal joint injuries.
