The femoral triangle in the anterior superior third of the thigh is a subfascial space that appears as a triangular depression inferior to the inguinal ligament; the depression is visible when the thigh is abducted, flexed, and laterally rotated. The femoral triangle is a subfascial space in the upper third of the thigh, bounded by the inguinal ligament, adductor and sartorius muscles. It contains vital structures such as the femoral nerve, artery, vein, lymph nodes and branches of the genitofemoral nerve. The femoral triangle (Scarpa’s triangle) is a inverted triangular-shaped subfascial space located within the superomedial aspect of the anterior thigh, which acts as a conduit for neurovascular structures passing from the pelvis to the upper thigh. The femoral triangle is an anatomical space in the anterior upper thigh that contains several palpable structures. The major boundaries can be recalled with the mnemonic SAIL 1,2: From lateral to medial 1: The basic order can be recalled with the mnemonics seen here.
