DISSECTION OF THE LOWER EXTREMITY 



L85 



After the ankle-joint has been studied, the tibia and fibula 

 should be sawn through about five centimetres above their lower 

 articular surfaces. Make a coronal section of the bones and 

 study the ligament passing between their lower extremities. 

 Establish the continuity of the synovial membrane of this joint 

 with that of the ankle. 



Remove the crucial ligament of the leg and the transverse 

 ligament of the foot, also the tendons passing over the ankle, 

 and dissect out the joints of the foot.

In removing the soft parts in order to expose the joint, take 

 great care not to injure the very delicate anterior part 

 articular capsule.
