Abstract
INTRODUCTION: Controversy remains regarding the optimal management of tarsometatarsal (Lisfranc) fracture dislocations. Open reduction and internal fixation (ORIF) and ORIF with primary arthrodesis (PA) have been described in the treatment of these injuries, although adverse sequelae remain problematic. Previous work has yielded small cohorts with heterogenous results. We aimed to describe the outcomes of Lisfranc fracture dislocations managed with ORIF and/or PA to identify risk factors for complications, such as nonunion and revision surgery.
METHODS: A retrospective review of 206 consecutive tarsometatarsal fracture dislocations that underwent surgical repair between 2015 and 2021 was performed. Time to radiographic union was noted. Complications were recorded, including revision surgery, infection, symptomatic implant removal, posttraumatic arthritis, secondary arthrodesis, and nonunion. A comparative subgroup analysis of outcomes by treatment modality (ie, PA versus ORIF) and by injury severity (isolated injury versus concomitant lower extremity fracture) were performed. Logistic regression analysis was performed to assess factors associated with revision surgery.
RESULTS: 104 patients met the inclusion criteria with a mean 13-month follow-up. Ninety-three (n = 93) patients underwent ORIF, and 11 patients underwent PA. Radiographic union was achieved in 94.2% of cases (98/104) at an average 106 days. Complications included superficial infection (3.8%), deep infection (7.7%), symptomatic implant removal (19.2%), posttraumatic arthritis (12.5%), secondary arthrodesis (4.8%), and nonunion (2.9%). No difference existed in the complication rates between those who underwent ORIF and those who underwent PA (P = 0.50). Revision surgery rates were similar between patients who sustained isolated injuries and those with concomitant lower extremity fractures (P = 0.31). Risk factors for revision surgery included open fractures (OR 4.01, P = 0.042) and previous psychiatric illness (OR 5.77, P = 0.016).
DISCUSSION: The vast spectrum of injury in Lisfranc fracture dislocations makes uniform treatment challenging. In this large consecutive series, few failed to achieve union or required secondary arthrodesis. Open fractures and previous psychiatric illness portended worse clinical outcomes. ORIF without PA remains a viable treatment in these injuries.
LEVEL OF EVIDENCE: Level III, retrospective cohort study.
