order to bring the powerful lateral and medial accessory ligaments more 

 fully into relief. At the same time the articulating surfaces will be dis- 

 played, and the play of the surfaces can be studied when the joint is flexed 

 and extended. 



Anterior and Posterior Segments of the Capsule (O.T. 

 Anterior and Posterior Ligaments). These are feeble bands 

 which are placed in front of and behind the joint. They 

 are attached to the margins of the articulating surfaces,

except in front and distally where the anterior segment is 

 fixed to the neck of the talus. The fibres of these liga- 

 ments have for the most part a transverse direction. 



The Lateral Accessory Bands (O.T. External Lateral 

 Ligament). The lateral accessory bands of the capsule of 

 the ankle-joint are three in number, (i) The anterior talo- 

 fibular ligament; (2) the posterior talo-fibular ligament; 

 (3) the calcaneo-fibular ligament. 



The anterior talo-fibular ligament is the most anterior of 

 the three. It is a flattened band which passes forwards from
