Treatment of Lisfranc Injuries Using Interosseous Suture Button: A Retrospective Review of 84 Cases With a Minimum 3-Year Follow-Up

Abstract

Lisfranc fracture dislocation is an injury often encountered by the foot and ankle surgeon. This injury, depending on the severity and level of energy, has been shown to lead to posttraumatic osteoarthritis and chronic pain if undiagnosed or improperly managed. The purpose of this study was to retrospectively evaluate the surgical repair with the use of an interosseous suture button for Lisfranc injuries with isolated ligamentous disruption. From 2008 through 2016, 104 patients were consecutively enrolled who underwent open reduction internal fixation (ORIF) of the Lisfranc complex with a suture button and stabilization of the medial and intermediate cuneiform with a 4.0-mm screw. Eighty-four patients were available for a 3-year minimum follow-up. The mean return to full weightbearing was 11 days protected in a controlled ankle motion (CAM) boot. American Orthopedic Foot & Ankle Society (AOFAS) and visual analog scale (VAS) scores improved from 30 and 8.4, respectfully, preoperatively to 90 and 1.3 postoperatively. The mean preoperative step-off between the second metatarsal base and intermediate cuneiform was found to be 3.15 mm. The immediate postreduction weightbearing radiograph measured 0.25 mm and 0.43 mm at the final follow-up evaluation, a difference that was found to be significant. There were no revision arthrodeses performed and no removal of the suture button during this time period. ORIF using an interosseous suture button appears to have an adequate medium-term patient satisfaction; however, there is evidence of minimal diastasis in some patients at 3 years postoperatively in ligamentous Lisfranc fracture dislocations.
