Treatment of the missed Lisfranc injury.

Abstract

Lisfranc joint injuries may be missed at the time of occurrence potentially leading to persistent instability, deformity, or arthritis. In the absence of significant residual arthritis or fixed deformity, delayed open reduction and internal fixation with or without reconstruction of the Lisfranc ligament may be performed. An alternative is reduction and primary arthrodesis of the relatively immobile medial tarsometatarsal (TMT) joints. In the presence of significant residual arthritis or fixed deformity that is recalcitrant to conservative treatment, arthrodesis, including correction of deformity, is the treatment of choice for the first, second, and third TMT joints. Resection arthroplasty of the fourth and fifth TMT joints may be preferable to arthrodesis in order to maintain physiologic motion.
