Comparison of two surgical techniques for Lisfranc injuries; closed reduction and fixation versus primary partial arthrodesis

BACKGROUND: This study reviewed the outcomes of Lisfranc injuries treated by primary partial arthrodesis (PPA) or closed re-duction and internal fixation (CRIF).METHODS: A retrospective review was made of patients who underwent PPA or CRIF for a Lisfranc injury after low-energy trauma, and follow-up was assessed according to radiographic, and clinical outcomes. A total of 45 patients with a median age of 38 years were followed up for an average of 47 months.RESULTS: The average American orthopaedic foot and ankle society (AOFAS) score was 83.6 points in the PPA group and 86.2 points in CRIF group (p>0.05). The mean pain score was 32.9 in the PPA group, 33.7 in the CRIF group (p>0.05). Secondary surgery for symptomatic hardware was required in 78% of the CRIF group and in 42% of the PPA group (p<0.05).CONCLUSION: Treatment of low-energy Lisfranc injuries with either PPA or closed reduction and fixation produced good clinical and radiological outcomes. The total AOFAS scores were comparable between two groups. However, the function and pain scores were seen to improve more with closed reduction and fixation while there was a greater requirement for secondary surgery in the CRIF group.
