Hypermobility of the first ray in patients with planovalgus feet and tarsometatarsal osteoarthritis

Foot structure and lower limb function in individuals with midfoot osteoarthritis: a systematic review

“…Characteristics of the 11 included studies are shown in Table I. Four studies were from the USA 8,20,22,23 , four studies from the UK 9,14,19,29 , one from Australia 13 , one from Japan 21 and one from South Korea 24 . Two USA studies 8,23 and two UK studies 9,14 used the same participants but analysed the data differently.…”

The symptomatic adult flatfoot: Is there a relationship between severity and degree of pre-existing arthritis in the foot and ankle?

“…[16] Furthermore, the increased likelihood of talonavicular osteoarthritis has been assessed in 32 planovalgus feet by Cowie et al Using an electric goniometer, the medial column of the foot was found to be pathologically more mobile in flexion and extension with increased lateral displacement forces. [17] The increased forces across the talonavicular joint have further been confirmed by Kitaoka et al in a series of biomechanical studies. [18][19][20] The authors therefore postulate that the abnormal biomechanics across the medial column in force, movement and translation, leads to pathological load on the talonavicular joint and great degree of degenerative joint disease.…”

Lapicotton technique in the treatment of progressive collapsing foot deformity

“…Tarsometatarsal arthrodesis is a traditional procedure for correction of forefoot varus in the setting of PCFD when severe medial column instability, TMT plantar gapping, local arthritis or hallux valgus is present (1,30,31) . Reliability of this technique and good functional results are usually the arguments that supports its indication (32,33) .…”
