SCARPA'S TRIANGLE (TRIGONUM FEMORALE) 



This triangle is on the front of the thigh. The base is formed 

 by the inguinal ligament, the lateral border by the upper half of 

 the sartorius, the medial border by the adductor longus, and the 

 apex by the crossing of these two muscles on the medial side of 

 the thigh at about the middle.

h, sartorius; i, medial head of gastrocnemius. 



The most important structures in the triangle are the femoral 

 artery and vein lying side by side, in a line from the middle of the 

 base to the apex. The femoral nerve and branches are on the 

 lateral side of the artery.
