DISSECTION OF THE DOG 106 



(ligamentum tarsi dorsalej joins fche neck of the talus to the cuboid and 

 third metatarsal bones. A small anterior talo-calcanean ligament (ligamentum 

 talo-calcaneum anterius) will be found in the depths of fche groove between Hu- 

 tu., bones with which it is associated. 



Dissection. Remove fche talus. This i> rendered difficult from the presence 

 of a strong interosseous ligament . 



Ligamentum talo-calcaneum interosseum. — The talo-calcanean interosseous 

 ligament passes between the two bones, and is attached to the grooves between 

 their articular facets. 



Ligaments connected with th calcaneus. — Removal of fche talus exposes both 

 Burfaces of fche strong plantar calcaneo-navicular ligartu nt (ligamentum calcaneo- 

 naviculare plantare), which passes from the sustentaculum tali to the navicular 

 bone. Pari of fche cavity in which the head of fche talus rests is formed by this 

 ligament. The long plantar ligament (ligamentum plantare longum) is powerful 

 and runs from the plantar surface of the calcaneus to fche tubercle on the cuboid 

 and on to fche tubercle at fche proximal end of the fifth metatarsal bone. Partly 

 undo- cover of. and much shorter than, the preceding is the plantar calcaneo- 

 cuboid ligament (ligamentum calcaneo-cuboideum plantare), which joins the 

 calcaneus to the cuboid only. On the dorsal and lateral part of the joint 

 between the calcaneus and cuboid is a short dorsal calcaneo-cuboid ligament 

 (ligamentum calcaneo-cuboideum dorsale), which may be regarded as a 

 thickening of the capsule of fche joint. 



Ligaments connected with tin navicular.— A. short dorsal cuboideo-navicUJar 

 ligament (ligamentum cuboideo-naviculare dorsale) joins the cuboid and 

 navicular on the dorsal aspect of the joint between the two bones. The 

 navicular and lateral cuneiform bones are united by a small dorsal navicular- 

 cuneiform ligament (ligamentum naviculari-cuneiforme dorsale). and a much 

 stronger plantar ligarm nt (ligamentum naviculari-cuneiforme plantare) joins the 

 navicular and the medial cuneiform bones. The latter is continued to the first 

 and second metatarsal bone-. 



Dissection. — Remove the calcaneus and the plantar calcaneo-navicular and 

 plantar navicular cuneiform ligaments. 



The dissection exposes a short plantar cuboideo-navicidar ligament 

 (ligamentum cuboideo-naviculare plantare) uniting the plantar aspects of 

 the navicular and cuboid bones. 



Articu1ati<>n<< tarso-metatarseai. — The metatarsal bones articulate with the 

 cuboid and the three cuneiform bones, with which they are connected by dorsal, 

 plantar, and interosseous ligaments. The dorsal ligaments are flattened bands 

 of no great strength. The interosseous ligaments should be examined along 

 with the interosseous tarsal ligaments.
