and obviating the bad effects which concussion would have been likely 

 to produce in the tarsus had it been one rigid structure. 



Directions. — The ligaments of the tarsus are both numerous and com- 

 plicated, and the best order of their dissection is that in which they are 

 hereafter described. Since one set of ligaments must be removed in 



Fig. 5. 



A. — Ligaments of the Tarsus, front view. 

 1. Superficial fasciculus of the internal lateral ligament (cut) ; 2. Middle fasciculus of the same 

 (two slips); 3. Deep fasciculus of the same; 4. Superficial fasciculus of the external lateral liga- 

 ment; 5. Deep fasciculus of the same ; fi. Astragalo-metatarsal ligament ; 7. Canal for the perfora- 

 ting metatarsal artery ; 8. Anterior cuhoido-cunean ligament ; 9. Anterior cuhoido-scaphoid liga- 

 ment ; 10. Cuboid insertion of the flexor metatarsi. 



B.— LlOAMENTS OF THE TARSUS, BACK VIEW. 



1. External lateral ligament; 2. Internal lateral ligament; 3. Tarso-metatarsal ligament; 

 4. Fibrocartilaginous thickening of the posterior ligament ; 5. Calcaneo-metatarsal ligament; 

 6. Subtarsal ligament, or check-band to perforans tendon ; 7. Suspensory ligament. 



order to expose the following set, the dissector should not proceed with 

 undue rapidity. 



Tibio-tarsal Ligaments. — These are four in number, viz., two lateral, 

 an anterior, and a posterior. 



The External Lateral Ligament consists of a superficial and a deep 

 fasciculus, which cross one another like the legs of the letter X. The 

 superficial division, which is the larger of the two, is fixed superiorly to 

 the posterior part of the external malleolus of the tibia, while inferiorly
