The two large inguinal tendons are the inguinal ligaments, which connect the anterior superior iliac spine to the pubic tubercle. The inguinal ligament is formed by the backward and upward reflexion of the tendinous membrane of the external oblique abdominal muscle from the anterior superior iliac spine to the pubic tubercle. The tendinous membrane of the external oblique abdominal muscle divides into two directions, upward and downward, at the mouth of the external ring, and a section of the lateral pedicle curves inward, passing over the surface and medial angle of the pubic bone, connecting with the white line of the abdomen, and participating in the anterior rib segment of the rectus abdominis muscle. The inguinal ligament is an important body surface marker for the body and is a common inguinal hernia. The function of the inguinal ligament is to immobilize, protect, and maintain the stability of the pelvis and lower extremities, and to effectively protect the blood vessels and nerves of the legs. Therefore, a strained inguinal ligament should be immediately applied with a cold compress, which will reduce swelling and stop pain, and avoid heavy bleeding that can cause pain and tissue adhesions. If there is any discomfort, you should seek medical attention.
