Lower Limbs Anatomy

Summary:

This Lower Limbs Anatomy text is a presentation given by Dr Ndayisaba Corneille, focusing on the femoral triangle and its related structures. The femoral triangle is a triangular area situated in the upper part of the thigh, specifically the medial aspect, located just below the inguinal ligament. Dr Ndayisaba highlights the boundaries, contents, and branches of this important anatomical region.

The boundaries of the femoral triangle are described, with the superior boundary being the inguinal ligament, the lateral boundary formed by the medial border of the sartorius muscle, and the medial boundary created by the medial border of the adductor longus muscle. The apex of the triangle is continuous with the adductor canal. The anterior wall comprises the fascia lata, while the posterior wall comprises the iliopsoas, pectineus, and adductor longus muscles.

The contents of the femoral triangle include the femoral nerve, femoral sheath, femoral artery and its branches, femoral vein and its tributaries, femoral canal, deep inguinal lymph nodes, and fatty tissue. Dr Ndayisaba explains the functions and clinical relevance of these structures.

The presentation concludes by mentioning conditions like a femoral hernia, which can occur when a loop of the intestine protrudes into the femoral ring within the femoral canal. Dr Ndayisaba discusses the potential complications and treatment of femoral hernia, emphasizing the importance of understanding the anatomy of the femoral triangle for accurate diagnosis and management.

A triangular depressed area is situated in the upper part of the medial aspect of the thigh just below the inguinal ligament.

Boundaries
 Superiorly (base) : the inguinal ligament
 Laterally: medial border of sartorius
 Medially: medial border of adductor longus
 Apex: continuous with adductor canal
 Anterior wall: fascia lata
 Posterior wall: consists of the iliopsoas, pectineus and adductor longus from lateral to the medial side
