1.1 Inguinal Hernia
The inguinal canal is a passage in the anterior abdominal wall that in men carries the spermatic cord and in women it is called as round ligament of uterus. The inguinal canal is larger in size and more prominent in men compared to women.1 The inguinal canal is made up of two walls (anterior and posterior), a roof, and a floor. The anterior wall is formed by the aponeurosis of the external oblique and the posterior wall is formed by the transversalis fascia and also the roof is formed by the transversalis fascia, transversus abdominis and internal oblique. The floor is made by the inguinal ligament (a ‘rolled up’ portion of the external oblique aponeurosis) and medially thickened by the lacunar ligament.2
The intra abdominal pressure is essential to maintain the normal integrity of inguinal canal. During periods of increased intra-abdominal pressure, the abdominal viscera are pressed into the inguinal canal and to prevent herniation, the muscles of the anterior and posterior wall contract, and ‘clamp down’ on the canal. There are two openings to the inguinal canal are deep and superficial rings. The deep (internal) ring is originated above the midpoint of the inguinal ligament which is lateral to the epigastric vessels. The ring is created by the transversalis fascia, which invigilates to form a covering of the inguinal canal contents.3 …show more content…

A direct inguinal hernia protrudes medial to inferior epigastric vessels when abdominal contents herniated through the external inguinal ring. It has been suggested that there is an increase in the intra-abdominal pressure during activity stressing the transversalis fascial fibers of the posterior inguinal wall. The Strong and tight hip flexors can tilt the pelvis forward and stretches the weak abdominal oblique muscle. Janda and Schmid described this as pelvic crossed
