Calcaneal fractures cause a lateral load shift in Chopart joint contact stress and plantar pressure pattern in vitro

Segmental foot mobility in individuals with and without diabetes and neuropathy

“…Reduced subtalar joint mobility, specifically inadequate calcaneal eversion has been documented in subjects with DM [6][7][8][9][10][11][12][13]. Reduced subtalar mobility may have significant biomechanical consequences [14,15] including increases in transverse tarsal joint rigidity predisposing to lateral column over-weighting. Similarly, limited first metatarsal mobility [12,16] has been hypothesized to result in reduced first metatarsal motion during gait in individuals with DM [17] thus predisposing to the development of foot ulcers.…”

Chopart's joint load during gait

“…Pathological conditions of the foot may lead to a change in distribution of weight-bearing between medial and lateral column of the foot. In an in vitro study, Rosenbaum et al [13] showed a higher pressure load following calcaneal fracture of the CC joint. The transfer of load from the hindfoot to the forefoot via the medial and lateral column of the foot appears to vary depending on the individual anatomy.…”

Fraturas intra-articulares do calcâneo: análise clínica e biomecânica

“…Os estudos biomecânicos, por sua vez, tendem a realizar caracterizações de variáveis em modelos experimentais e espécimes anatômicos (peças de cadáver), o que traz alta sensibilidade nos testes sem, contudo, avaliar situações reais desse tipo de trauma (1)(2)(3)(4)(5)(6)(7) . Entretanto, estudos como os de Kitaoka et al (8) , Siegmeth et al (9) e Contreras et al (10) já incluem os aspectos clínicos, relevantes às fraturas de calcâneo.…”
