The Lateral Column Lengthening and Medial Column Stabilization Procedures

Arthrodesis Techniques in the Management of Stage-Ii and Iii Acquired Adult Flatfoot Deformity

“…Lengthening of the lateral column has been shown to restore the medial arch and correct hindfoot valgus and forefoot abduction 17,18 . The decision whether to perform a lengthening osteotomy through the distal part of the calcaneus or with distraction arthrodesis of the calcaneocuboid joint is controversial 7,19 .…”

“…The decision whether to perform a lengthening osteotomy through the distal part of the calcaneus or with distraction arthrodesis of the calcaneocuboid joint is controversial 7,19 . Proponents of distraction arthrodesis of the calcaneocuboid joint cite the potential for the development of degenerative changes at the calcaneocuboid joint following osteotomy of the calcaneus as a result of increased contact pressures at the calcaneocuboid joint 4,[16][17][18][19][20][21] ; however, the nonunion rate following distraction arthrodesis of the calcaneocuboid joint is approximately 20%. Typically, if lateral column lengthening is required as a component of the correction of a flexible Stage-II acquired adult flatfoot deformity, a lengthening osteotomy of the calcaneal neck with interposition of bone graft is performed.…”

“…Symptomatic nonunion is treated with bone-grafting and plate, screw, or staple fixation. Chi et al reported that eight of forty-one attempted distraction arthrodeses of the calcaneocuboid joint in thirty-six patients did not result in healing 18 . Distraction arthrodesis of the calcaneocuboid joint causes some loss of motion in the foot, but less than is seen after subtalar or talonavicular arthrodesis 21 .…”

Assessment of the medial longitudinal arch in children and adolescents with obesity: footprints and radiographic study

“…Different measurements have been proposed to assess radiographically the MLA height and some authors have related them to foot structure [5,23,28,33,37,48]. Among these measurements, the talus-first metatarsal angle (TFMA) is described as the most consistently accurate radiographic parameter of flatfoot [48] (Fig.…”

Impacto de dois níveis de obesidade grave sobre as alterações ostearticulares e funcionais de joelho e pé

“…Diferentes medidas têm sido propostas para se avaliar a altura do ALM 49,50,51 , entre estas, o ângulo tálus-primeiro metatarso tem sido descrito como um dos mais fidedignos 51 . Entretanto não há um consenso, clínico ou radiológico, sobre qual o melhor método e/ou medida para se avaliar pé plano ou pronado 52 .…”
