Patient-Reported Outcomes after Long-Term Follow-Up of Lisfranc Injuries Treated with Open Reduction Internal Fixation

Abstract

Category:Midfoot/Forefoot; TraumaIntroduction/Purpose:Lisfranc injuries are thought to contribute to debilitating outcomes in polytrauma patients. Due to the relative rarity of Lisfranc injuries, consistent long-term follow-up is a challenge and clinical outcomes are difficult to assess in this patient population. As a result, there exists a need for further investigation into patient-related clinical outcomes after Lisfranc injury. The purpose of this study was to collect long-term clinical outcome data following Lisfranc injuries using PROMIS Physical Function (PROMIS-PF) and Visual Analogue Scale-Foot and Ankle (VAS-FA).Methods:A chart review was performed to identify all patients who had surgical treatment of an acute Lisfranc injury at our institution from 2005 to 2014. Of forty-five patients identified, we were able to recruit nineteen for a follow-up clinic visit consisting of a physical exam, administration of questionnaires addressing pain and medication usage, radiographs, and completion of outcome surveys including PROMIS-Physical Function and Visual Analogue Scale-Foot and Ankle.Results:There were 14 female and 5 male patients enrolled in the study with a mean time of 6.25 years from the time of injury. Within this cohort, the mean PROMIS-PF score was 52.4+-8.2 and the mean VAS-Foot and Ankle Score was 76.6+-22.3. The risk factors of age, gender, BMI, smoking status, depression, and time from injury showed no statistically significant association with PROMIS-PF or VAS-FA scores using p<0.05 (Table 1).Conclusion:We report satisfactory long-term patient-reported outcomes using PROMIS-PF and VAS-FA independent of several risk factors. However, the small sample size and observational nature of our study contributed to the lack of significance in the data and limit our ability to further infer which patients would be expected to do worse postoperatively.
