Flexible flatfoot is a normal foot shape that is present in most infants and many adults. The arch elevates spontaneously in most children during the first decade of life. There is no evidence that a longitudinal arch can be created in a child's foot by any external forces or devices. Flexible flatfoot with a short Achilles tendon, in contrast to simple flexible flatfoot, is known to cause pain and disability in some adolescents and adults. Joint-preserving, deformity-correcting surgery is indicated in flexible flatfeet with short Achilles tendons when conservative measurements fail to relieve pain under the head of the plantar flexed talus or in the sinus tarsi area. Osteotomy is the fundamental and central procedure of choice. In almost all cases, Achilles tendon lengthening is required. In some cases, rigid supination deformity of the forefoot is present, requiring identification and concurrent treatment.

“…Flat feet are an acquired or developmental deformity that is progressive and is characterized by supination and abduction of the fore foot and decrease in the longitudinal arch height 2) . Generally, flat feet are defined as a feet with an abnormally low medial arch height as measured during weight-bearing stance 3) .…”

Differences in Plantar Foot Pressure and COP between Flat and Normal Feet During Walking

et al. 2011

Abstract.[Purpose] The purpose of this study was to compare the peak plantar foot pressure and the pathway of the center of pressure (COP) between normal and flat feet. [Subjects and Methods] Nineteen subjects (10 normal feet, 9 flat feet) participated in this study. Plantar foot pressure was recorded by the Matscan system (Tekscan, Boston, USA) while walking upright. Plantar foot surface was divided into seven regions for pressure measurement: two toe regions, three forefoot regions, one midfoot region, and one heel region. The independent t-test was used to compare plantar foot pressures between normal adults and patients with flat feet. The pathway of COP in normal and flat feet was observed macroscopically.[Results] The plantar foot pressures of the 4th-5th metatarsal head and heel regions in the flat feet group were less than those of the normal feet group. The pathway of COP of normal feet group had a tendency to shift medially in the forefoot but the pathway of COP in the flat feet group had a tendency to be straight in the forefoot.[Conclusion] The results indicate that the plantar foot pressure of a flat foot was lower than that of a normal foot and the pathway of COP of a flat foot may be different from that of a normal foot. We believe that reduction of the longitudinal arch of foot in flat feet explains these results.

“…Models vary in terms of the number of segments, definitions of segments, coordinate alignments and use of static offsets. These models have been validated and are being used to research pathological conditions and treatment strategies in posterior tibial tendon dysfunction (Neville and Houck, 2009), diabetes (Sawacha et al, 2009), adult flat foot (Arangio et al, 2007) and rheumatoid arthritis (Woodburn et al, 2004) among others. Till date, no multi-segment kinematic foot model has been used as part of a musculoskeletal model.…”
