BackgroundPercutaneous fixation of Lisfranc injuries is potentially less invasive to traditional open techniques but evidence of any clinical benefit is lacking. The aim of this study is to compare the clinical outcomes of percutaneous reduction and internal fixation (PRIF) of low energy Lisfranc injuries with a matched, control group of patients treated with ORIF.MethodsOver a seven-year period (2012-2019), 16 consecutive patients with a low energy Lisfranc injury (Myerson B2-type) were treated with PRIF. Patient demographics, injury mechanism and radiological outcomes were recorded within a prospectively maintained database at the institution. This study sample was matched for age, sex and mechanism of injury to a control group of 16 patients with similar low energy Lisfranc injuries (Myerson B2-type) treated with ORIF. Clinical outcome was compared using the American Orthopaedic Foot and Ankle Society (AOFAS) midfoot score and Manchester Oxford Foot Questionnaire (MOXFQ).ResultsAt a mean follow up of 43 months (95% CI 35.6 - 50.4), both the AOFAS and MOXFQ scores were significantly higher in the PRIF group compared to the control ORIF group (AOFAS 89.1vs 76.4, p=0.03; MOXFQ 10.0 vs 27.6, p=0.03). There were no immediate postoperative complications in either group. There was no radiological evidence of midfoot osteoarthritis in the PRIF group, three patients in the ORIF group developed midfoot osteoarthritis (p=0.2).ConclusionsPRIF of low energy Lisfranc injures is a safe, minimally invasive technique and is associated with better mid-term clinical outcomes compared to ORIF.Copyright © 2020 Elsevier Ltd.
