Combined medial column arthrodesis with open reduction internal fixation of central column for treatment of Lisfranc fracture-dislocation: a review of consecutive cases
- View All
Lisfranc fracture-dislocations can be devastating injuries with significant long-term sequelae with or without surgical intervention. The main goal of treatment is to minimize the common long-term complications including pain, progressive arch collapse, degenerative joint disease, hardware failure, and reoperation. Partial primary fusion involving the first, second, and third tarsometatarsal joints has become a common approach for primarily dislocation injuries, with open reduction and internal fixation (ORIF) favored for Lisfranc injuries involving fracture. ORIF commonly requires revision surgery for hardware removal or delayed fusion. Major revision creates hardship for the patient due to the prolonged recovery required, and even "simple" hardware removal can be traumatic to local nerve, artery, and tendon structures. A common injury pattern includes the findings of primary dislocation and instability of the first tarsometatarsal joint with oftentimes comminuted fracture to the second and third tarsometatarsal joints, which does not fit the standard surgical approach. We report a review of our preferred surgical approach consisting of medial column primary arthrodesis combined with central column ORIF and lateral column temporary pinning. We undertook an institutional review board-approved review of 35 consecutive Lisfranc injuries treated with this hybrid approach. Mean follow-up time was 22.14 +/- 22.39 (range 2.5 to 84) months. All but 2 (5.71%) patients had radiographic evidence of union at 10 weeks. Complications included 3 with neuritis, 1 with medial column nonunion that was treated with a bone stimulator, and 1 with revision of second metatarsal nonunion. The present retrospective series highlights our experience with isolated primary fusion of the medial column in both subtle and obvious Lisfranc injuries.
