ridge above the articular facet for the cul)oid, and also to the up})er part of the 

 internal surface close to the articular margin, and passes forwards to be attached to 

 tlie depression on the internal surface of the cuboid, and also to the rough angle 

 between the internal and inferior surfaces. At tlie calcaneuni this ligament is 

 closijly connected witli the external calcaneo-scaphoid ligament. Towards the sole 

 it is connected with the short inferior calcaneo-cuboid ligament, and superiorly 

 with the dorsal calcaneo-culxiid. 



The dorsal calcaneo-cuboid (fig. 256) is attached to the dorsal surfaces of the 

 two bones, extending low down externally to blend with the outer part of the 

 short plantar ligament. Over the inner half, or more, the ligament stretches some 

 distance l)eyond the margins of the articular surfaces, reaching well forwards upon 

 the cuboid to l)e attacht^l about midway between its anterior and jjosterior borders;

The long inferior calcaneo-cuboid (tlie long plantar) (fig. 257) is a strong 

 dense band of tiljres which are attached posteriorly to the whok' of the under 

 surface of the calcaneuni l)etween the posterior tubercles and the rounded eminence 

 (the anterior tuljercle) at the anterior end of the bone. Most of its fibres pass 

 directly forwards, and are fixed to the outer two-thirds or more of the oblique 

 ridge behind the peroneal groove on the cuboid, while some pass further forwards 

 and inwards, expanding into a broad layer, and are inserted into the bases of the 

 second, third, fourth, and inner half of the fifth metatarsal bones. This anterior 

 expanded portion comi)letes the canal for the peroneus longus tendon, and from its 

 under surface arise the adductor hallucis and the^<'.ror hrevis minimi digit i nmscles.
