Abstract

Introduction Open reduction internal fixation (ORIF) and primary arthrodesis are two conventional options for the treatment of Lisfranc injuries. However, they are associated with implant-related complications. An alternative suspensory device construct using interosseous nonabsorbable sutures with endobuttons has been described with satisfactory results. This study aims to explore functional outcomes after suture button fixation of Lisfranc injuries in a Southeast Asian population. Methods This was a single-surgeon retrospective study of patients with Lisfranc injuries treated surgically using a suture button fixation technique between 2017 and 2019. Data collected included demographic information, pre-injury levels of activity, nature of injury, and type of surgery performed. The minimum postoperative follow-up was one year. The Foot and Ankle Outcome Score (FAOS) and Foot and Ankle Ability Measure (FAAM) were used to evaluate patient-reported outcomes. Scores were reported in percentage (%) with median and interquartile range. Results Twenty-nine patients with a mean age of 29 years (21-76) were recruited. Sixteen underwent suture button fixation only (SB), and 13 underwent suture button fixation with intercuneiform screw fixation and plating (SBM). The median scores for the FAOS and FAAM questionnaires were at least 80% in all domains. Twenty-eight patients (97%) were able to return to pre-injury activity level, 27 patients (93%) were able to return to sports. Only one patient was not satisfied with the outcomes of surgery. No patients had post-traumatic arthritis or hardware failure necessitating implant removal at the final follow-up. Conclusion This study has demonstrated that treatment of Lisfranc injuries with a suspensory device construct resulted in good outcomes with 97% of patients being able to return to pre-injury activity levels, and 93% of patients being able to return to sports. It may not be necessary to perform primary arthrodesis in uncomplicated Lisfranc injuries. This technique is also advantageous as implant removal is not routinely required due to the design and biomechanical properties of suspensory devices.
