Peritalar destabilisation syndrome (adult flatfoot with degenerative glenopathy).
In cases of adult acquired flatfoot associated with peritalar destabilisation, special reference is made to the plantar calcaneo-navicular (spring) ligament's degenerative disease (degenerative glenopathy) and to the presence of the accessory navicular bone as a possible pathogenic cause. Peritalar destabilization syndrome is proposed for the articular (subtalar and talo-navicular joints) or tendinosis (tibialis posterior tendon) separately or in association with degenerative glenopathy of the coxa pedis. In degenerative glenopathy surgical reconstruction of the glenoid also makes use of a posterior tibial split to create a new tibial-navicular ligament. The concept of pronatory syndrome deemed as the root the pathological subtalar pronation, which is an entirely secondary factor in peritalar destabilisation, must be questioned. We must keep in mind that subtalar pronation and supination are respectively subsequent to opening and closing of the coxa pedis (talo-calcaneo-navicular joint) kinetic chain.
