The inguinal ligament (/ ˈ ɪ ŋ ɡ w ɪ n ə l / [1] [2]), also known as Poupart's ligament or groin ligament, is a band running from the pubic tubercle to the anterior superior iliac spine. It forms the base of the inguinal canal through which an indirect inguinal hernia may develop.
The conjoint tendon (previously known as the inguinal aponeurotic falx) is a sheath of connective tissue formed from the lower part of the common aponeurosis of the abdominal internal oblique muscle and the transversus abdominis muscle, joining the muscle to the pelvis. It forms the medial part of the posterior wall of the inguinal canal.
The inguinal canals are situated just above the medial half of the inguinal ligament. The canals are approximately 4 to 6 cm long, [1] angled anteroinferiorly and medially. In males, its diameter is normally 2 cm (±1 cm in standard deviation) at the deep inguinal ring. [2] [notes 1] A first-order approximation is to visualize each canal as a ...
The superior-most node is situated in the groin, deep to the inguinal ligament, and is termed the Cloquet's node (also Rosenmuller's node). [7] It can instead be considered as the inferior-most of the external iliac lymph nodes. [8] [citation needed] Cloquet's node is also considered as a potential sentinel lymph node. [7] [9]
Sharp pain that doesn’t improve after a couple of weeks may be a sign of a serious condition, such as a severe muscle tear, ligament injury, fracture, or hip strain. Sudden dull pain.
Femoral nerve and its terminal branches - The nerve enters the femoral triangle by passing beneath the inguinal ligament, just lateral to the femoral artery. In the thigh, the nerve lies in a groove between iliacus muscle and psoas major muscles, outside the femoral sheath, and lateral to the femoral artery.
Inguinal triangle is labeled in green. Borders: inferior epigastric artery and vein: labeled at center left, and run from upper right to bottom center. inguinal ligament: not labeled on diagram, but runs a similar path to the inguinal aponeurotic falx, labeled at bottom. rectus abdominis muscle: runs from upper left to bottom left.
It passes under the inguinal ligament to reach the thigh. It supplies sensation to the skin on the lateral part of the thigh by an anterior branch and a posterior branch. The lateral cutaneous nerve of the thigh can be investigated using ultrasound .
