Peritalar destabilisation syndrome: adult flat foot in degenerative glenopathy

In acquired adult flat foot due to peritalar destabilisation, special reference is made to the degenerative pathology of the plantar calcaneo-scaphoid ligament, or spring ligament (degenerative glenopathy) and to the presence of an accessory scaphoid bone as the possible pathogenetic factor. The peritalar destabilisation syndrome is proposed in relation to the pathology of joint “coxa pedis” (subastragalic and astragalo-scaphoid), myotendinous (posterior tibial), and due to degenerative glenopathy. The surgical reconstruction of the glena is accompanied by the creation of a tibio-scaphoid neo-ligament with strip of posterior tibial tendon. The concept of pronatory syndrome, understanding as primary the pathological pronation of the subastragalic which, in peritalar destabilisation, is quite secondary, is disputable. It should be borne in mind that pronation and supination of the subastragalic are respectively consequences of the opening and closing of the kinetic chain of coxa pedis.
