Aims/Background: Current literature recommends that unstable Lisfranc joint fracture-dislocations be treated with open reduction and internal fixation. There are limited regional data regarding the outcomes of surgical management of these injuries. The primary aim of our study is to explore patient-reported outcomes of surgically managed unstable Lisfranc injuries as limited locoregional data are detailing such outcomes. Secondarily, we aim to compare differences in outcomes between patients who had implants removed and those who retained their implants.
Materials and methods: We performed a single-center, single-surgeon, retrospective review of 17 cases diagnosed with Lisfranc injuries treated surgically at our center from 2016 to 2017. Seventeen patients were followed up for an average of 24 months (range 21–34 months). Thirteen patients had their implants removed at an average of 5.9 months. Patients were assessed using Patient-reported Outcome Measures (SF-36), American Orthopaedic Foot and Ankle Society (AOFAS) Midfoot score, and Foot Function Index (FFI).
Results: In our review, we found that the commonest type of repair was with transarticular screws. Of the 17 patients assessed, we derived a mean FFI score of 13.7% (scale of 0–100%, with a higher percentage indicating worse function and increased disability). Most patients showed decreased function with more strenuous activities. The average AOFAS midfoot score was 81.5, with most patients losing points for mild pain and limitations with recreational activities. The average SF-36 physical functioning score (PFS) was 80.9 (scale of 0–100, higher scores indicating better physical function), and the average SF-36 mental health score (MHS) was 95.8.
Conclusion: In relation to available literature, the vast majority of our patients showed comparably good outcomes as measured using functional outcome and quality of life assessment scores.
