The primary goal of triple arthrodesis for stage III and IV adult acquired flatfoot is to obtain a well-aligned plantigrade foot that will support the ankle in optimal alignment. Ancillary procedures including posterior muscle group lengthening, medial displacement calcaneal osteotomy, medial column stabilization, peroneus brevis tenotomy, or transfer and harvest of regional bone graft are ofte...

The calcaneonavicular (spring) ligament complex is the soft tissue most often seen to fail in flatfoot pathology and is associated with deformity of the talonavicular joint. The spring ligament complex supports the talar head, preventing it from displacing into excessive plantar flexion/adduction. An anatomical reconstruction of the spring ligament should replicate this function. A new method o...

The advancement of 3D printing and scanning technology enables the digitalization customization foot orthosis with better accuracy. However, customized insoles require rectification to direct control and/or correct deformity, particularly flatfoot. In this exploratory study, we aimed at two design features (arch stiffness arch height) using three sets 3D-printed support (R+U+, R+U?, R?U+). coul...

PURPOSE The effect of paediatric flexible flatfeet (PFF) on health-related quality of life (HRQOL) has not been investigated. In this prospective cross-sectional study, the HRQOL of children with PFF was compared to those with typically developing feet (TDF) using two validated measures. We hypothesised that reduced HRQOL would be observed in children with PFF. The reliability of parents' perce...

We discuss flat compactifications of supergravities in diverse dimensions in the presence of branes. The compactification is induced by the scalar fields of supergravity and it is such that there is no relic cosmological constant on the brane, rendering this way the latter flat. We discuss in particular the D = 4, N = 2, 4 and D = 8, N = 1 supergravities with n = 1, 2, 3 vector multiplets where...
