“Coxa pedis” is reproposed as a talo-calcaneo-navicular joint complex that includes the astragalo-scaphoid and anterior subastragalic (talo-peritalar joint). Peritalar stability derives from skeletal congruence, the structures of the peritalar ligamentous complex and the action of the posterior tibial, long flexor of the hallux and long flexor of the toes induced proprioceptively by the peritalar proprioceptive system supported by the corresponding ligamentous complex. Intrinsic osteo-articular or gleno-ligamentous, or myotendinous, neurological or biomechanical pathology due to supra-segmentary imbalances may determine peritalar destabilisation with secondary pronation of the subastragalic simultaneously with supination of the astragalo-scaphoid. The secondary aspect of pronation of the subastragalic calls into question the concept of pronatory syndrome whereby abnormal pronation of the subastragalic is indicated as the cause of distal destabilisation of the foot structure with respective cascade pathology.
