The concept of “coxa pedis” is discussed and reference made to accessory bones which, acting on the peritalar joint complex, may be responsible for pathology of “coxa pedis”. Less important in this process are the accessory sustentacular bone the secondary calcaneal bone which by assimilation may determine respectively talo-calcaneal medial and calcaneo-navicular synostosis; of particular interest is the accessory scaphoid bone. A possible cause of conflict with footwear, or insertional tenopathies of the tibialis posterior tendon and or supero-medial peritalar destabilisation with initial eversion of a cavo-valgus foot, more recently encountered, also in a young age; recently are pictures of degenerative glenopathy due to conflict of the indovate accessory between posterior tibialis tendon and glena. Its exeresis if small; if voluminous and extensive on the plantar its medial regularisation and osteodesis of the residue at the scaphoid; this to prevent plantar structural destabilisation of the cotyle pedis.
