ARTHROLOGY 69 



The ligamentum interosseum is a delicate ligament located between 

 the tibia and fibula (Fig. 25, No. 4) which very early becomes 

 ossified. 



Ligaments of the Tibio-metatarsal Joint (Fig. 16). The -tibia- 

 tarsal joint is made up of the tibia and metatarsus. 



The ligamentum capsulare ossis tibio-metatarsi connects the tibia 

 and the metatarsus and surrounds the joint (Fig. 16, Nos. A, 7 and 



C, 7). 



The ligamentum externum, a long strong ligament, originates on 

 the upper and outer surface of the external condyle, or condylus 

 externus of the tibia and is attached to the upper rim of the os 

 metatarsi (Fig. 23, No. 15). 



The ligamentum anticum is spread out between the fossa inter- 

 condyloidea of the tibia and the tuberculum ossis metatarsi of the 

 proximal end of the metatarsus (Fig. 16, No. C, 3). Just posterior 

 to this ligament, there is an interosseous ligament, the ligamentum 

 interosseum. 



A semilunar pad of fibrous cartilage, the cartilago semilunaris 

 is located between the outer distal extremity of the tibia and upper 

 articular surface of the metatarsus (Fig. 16, No. C, 6). Its concave 

 portion is directed anteriorly and receives an insertion from the 

 ligamentum externum, or external ligament. 



The tendon Achillis (Fig. 16, No. A, i) may become ossified. 



Ligaments of the Toes (Fig. 16). In addition to the capsular 

 ligaments, which all true joints have, we find the following in con- 

 nection with the toes: 



The ligamentum superius and the ligamentum inferius connect 

 the second toe with the great toe, or hallux. 



The ligamentum laterale externum and the ligamentum laterale 

 internum unite the bases of the second, third and fourth toes to 

 the lateral faces of the trochleas of the inferior extremity of the 

 metatarsus. 



The bases of the toes are held together by the ligamenta transversa. 

 All the rest of the toes are held together by the ligamenta capsularia 

 digitorum pedis and by two lateral ligaments, namely: the ligamentum 

 laterale externum and the ligamentum laterale internum.
