Abstract

To evaluate patients with tarsometatarsal fractures and dislocations and describe complications and secondary operations. Retrospective cohort study. Level 1 trauma center. Consecutive adults treated acutely for Lisfranc injuries with reduction and fixation using standard techniques of rigid medial fixation and flexible lateral fixation. Complications include infections, wound healing problems, nonunion, malunion, and posttraumatic arthrosis (PTA), and secondary unplanned procedures after a minimum of 2-year radiographic follow-up. Mean age of the included 118 patients was 40 years (range, 18-73 years) and 96 (74%) were male. Comorbidities included obesity (n = 32; 40%), diabetes mellitus (n = 12; 9%), and tobacco use (n = 67; 52%). Thirty (23%) were open injuries, and concomitant forefoot injuries were present in 47% and hindfoot injuries in 12%. Unplanned secondary procedures, including implant removals, were performed on 39 patients (33%), most often for removal of painful implants (26%) or infectious debridement (9%). Sixty-seven complications occurred, with PTA most frequent (37%). Deep infections occurred in 8%. On multivariate analysis, open injury ( P = 0.028, CI = 1.22-30.63, OR = 6.12) and concomitant forefoot injury ( P = 0.03, CI = 1.12-9.76, OR = 3.31) were independent risk factors for complication. Open Lisfranc injuries were associated with complications, with deep infections occurring in 9%. Secondary procedures were most often performed for pain relief; the most common late complication was PTA, warranting counseling of patients about potential long-term sequelae of injury. Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.
