Excerpt
The study by Podolnick and colleagues speculated that pes cavus deformity (an acquired deformity characterized by an inverted hindfoot, a high arch, forefoot suppinaion, and a plantar flexed first ray) may result in abnormal forces in the tarsal-metatarsal joint by virtue of a locked hindfoot, resulting in a potentially increased risk of Lisfranc injury. This notion was supported by rigorous analysis of known radiographic measurements characteristic of pes cavus deformity observed in individuals with Lisfranc injuries in excess of that expected in patients with “normal feet.” Despite the retrospective nature and inherent biases of the study, the presumed connection between the pes cavus deformity and Lisfranc injury [
