The inguinal 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 inguinal canals are the two passages in the anterior abdominal wall which in males convey A hernia that exits the abdominal cavity directly through the deep layers of the abdominal wall, thereby bypassing the inguinal canal, is known. Inguinal Hernia: Anatomy and Management is intended for general surgeons and hernia specialists. The goal of this activity is to define current treatment.

Views Read Edit View history. The inguinal canals are larger and more prominent in males. Retrieved 10 February Representation of the superficial and deep transverse fasciae.
This anatomic region was originally coined by Dr. Journal List Ann Transl Med v. Indirect inguinal hernias are the more common of the two types. The iliopubic tract is a thickened tendinous structure of the transverse abdominal fascia that connects the anterior superior iliac spine and the pubic tubercle and parallels the inguinal ligament Figure Written informed consent was obtained from the patient for publication of this manuscript and any accompanying images. A first-order approximation is to visualize each canal as a cylinder.
This section needs expansion. This article antaomi anatomical terminology; for an overview, see anatomical terminology. The space of Bogros is located lateral to the space of Retzius and is bound anteriorly by the superficial transverse fascia, medially by the inferior epigastric blood vessels, laterally by the pelvic wall, and posteriorly by the psoas muscle, the external iliac vessels and the femoral nerve. Abdominal contents potentially including intestine can be abnormally displaced from the abdominal cavity.

The deep transverse fascia becomes a funnel-shaped structure that extends downward to cover the spermatic cord structures the inguina,is deferens, the testicular vessels and the hernia sac of the oblique inguinal at the internal inguinal ring and becomes the internal spermatic fascia entering the inguinal canal. Meta-analysis and review of prospective randomized trials comparing laparoscopic and Lichtenstein techniques in recurrent inguinal hernia repair.
The iliopubic tract is the outer boundary of the triangle of pain. Inguinal triangle Inguinal canal Deep inguinal ring Superficial inguinal ring Intercrural fibers Crura of superficial inguinal ring Inguinal ligament Pectineal ligament Lacunar ligament Reflected ligament.
The ring is created by the transversalis fascia, which invaginates to form a covering of the contents of the inguinal canal. A hernia that exits the abdominal cavity directly through the deep layers of the abdominal wall, thereby bypassing the inguinal canal, is known as a direct inguinal hernia.
During laparoscopic inguinal hernia repair, it is important to recognize the following important structures in the abdominal cavity: Muscles and ligaments of abdomen and pelvis. The white iliopubic tract can be seen at the lower edge of a direct hernia ring or below an internal inguinal ring.
In both sexes the canals transmit the ilioinguinal nerves. Colles’ ligament is infuinalis ligament not inguinal ligament. Lower anterior abdominal wall, transverse fascia and spaces the right lower anterior abdominal wall is taken inguinalix an example. Discuss Proposed since August The mid-inguinal point, halfway between the anterior superior iliac spine and the pubic symphysis, is the landmark for the femoral artery.
Anatomy essentials for laparoscopic inguinal hernia repair
Inguinal hernia, laparoscopic repair, anatomy. Otherwise, the stapler head is likely located below the iliopubic tract, and stapling may cause nerve damage.
The lateral femoral cutaneous nerve runs just below the iliac fascia and enters the thigh in the 1- to 4-cm-wide region infero—medial to the anterior superior iliac spine under the iliopubic tract. The separation is required to access the space of Bogros due to the relatively tight fusion of the transverse abdominal fascia and the peritoneum. A single-side repair of the myopectineal orifice can simultaneously and completely repair the site of anatomical weakness for inguinal, direct and femoral hernias.
It has been suggested that Superficial inguinal ring be merged into this article. Direct inguinal hernias, oblique inguinal hernias and femoral hernias are all caused by weakness of the abdominal transverse fascia in myopectineal orifice Figure inguinnalis.

The Inguinal Canal
Fig 2 — The descent and embryological development of the testes. Such symptoms can resolve spontaneously in 2—4 weeks. Prosection 1 — The superficial inguinal ring and contents of the inguinal canal. The identification of the inferior epigastric vessels is very important before accessing the space of Bogros. Important anatomic structures and landmarks During laparoscopic inguinal hernia repair, it is important to recognize the following important structures in the abdominal cavity: There is some dispute over the attachments.
Inguinal canal – Wikipedia
Both types of inguinal hernia can present as lumps in the scrotum or labia majora. The inguinal crural ligament runs from the anterior superior iliac crest of the ilium to the pubic tubercle of the pubic bone. The authors have no conflicts of interest to declare.
