[Taloscaphoid arthrodesis and foot statics].

The talo-navicular joint takes a part in both talocalcaneal and midtarsal joints's motion. Its arthrodesis produces all but suppression of subtalar joint motion. If there is surgical indication for deformed but flexible foot, better than a standard resectional subtalar arthrodesis, talo-navicular arthrodesis, with easy technique, is successful to maintain correction in right position, specially for valgus flat foot.
