The femoral triangle is a wedge-shaped depression formed by muscles in the upper thigh at the junction between the anterior abdominal wall and the lower limb (Fig. 6.42):
The base of the triangle is the inguinal ligament.
The medial border is the medial margin of the adductor longus muscle in the medial compartment of the thigh.
The lateral margin is the medial margin of the sartorius muscle in the anterior compartment of the thigh.
