It is applied by the

and the posterior articular facet of the navicular bone, thus form a continuous articular surface for the head of the astragalus. The inferior 

 surface of the cartilago navicitlaris, likewise cartilaginous in texture, forms, as shown in Fig. 487, the groove for the tendon of the

FIG. 487. THE ARTICULAR SURFACES OF THE ASTRAGALOCALCANEONAVICULAR ARTICULATION, THK DEEP LIGAMENTS 

 OF THE DORSUM OF THE FOOT, THE METATARSOPHALANGEAL AND INTERPHALANGEAL ARTICULATIONS OF THE 

 TOES. (THE RIGHT FOOT SEEN FROM THE DORSAL SIDE.) 



The capsule of the astragalocalcaneal articulation was removed, with the exception of the internal astragalocalcaneal 

 ligament ; the capsule of the astragalonavicular articulation was also removed with the exception of its internal and 

 plantar walls ; and. after removing the interosseous astragalocalcaneal ligament, the astragalus was rotated inwards 

 (on the internal astragalocalcaneal ligament as a hinge), until its inferior surface looked directly upwards.
