Iliopubic Tract
The iliopubic tract is a thickened band of fibers curving over the external iliac vessels, at the spot where they become femoral, on the abdominal side of the inguinal ligaments and loosely connected with it. It is apparently a thickening of the transversalis fascia joined laterally to the iliac crest, and arching across the front of the femoral sheath to be inserted by a broad attachment into the pubic tubercle and pectineal line, behind the conjoint tendon. In some subjects this structure is not very prominently marked, and not infrequently it is altogether wanting. It can be of clinical significance in hernia repair Hernia repair refers to a surgical operation for the correction of a hernia—a bulging of internal organs or tissues through the wall that contains it. It can be of two different types: herniorrhaphy; or hernioplasty. This operation may be perfo ....

External Iliac Vessels (other)

Inguinal Ligament
The inguinal ligament (), 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. Structure The inguinal ligament runs from the anterior superior iliac crest of the ilium to the pubic tubercle of the pubic bone. It is formed by the external abdominal oblique aponeurosis and is continuous with the fascia lata of the thigh. There is some dispute over the attachments. Structures that pass deep to the inguinal ligament include: *Psoas major, iliacus, pectineus *Femoral nerve, artery, and vein *Lateral cutaneous nerve of thigh *Lymphatics Function The ligament serves to contain soft tissues as they course anteriorly from the trunk to the lower extremity. This structure demarcates the superior border of the femoral triangle. It demarcates the inferior border of the inguinal triangle. The midpoint of the ingui ...

Transversalis Fascia
The transversalis fascia (or transverse fascia) is a thin aponeurotic membrane of the abdomen. It lies between the inner surface of the transverse abdominal muscle and the parietal peritoneum. It forms part of the general layer of fascia lining the abdominal parietes. It is directly continuous with the iliac fascia, the internal spermatic fascia, and pelvic fasciae. Structure In the inguinal region, the transversalis fascia is thick and dense. It is joined by fibers from the aponeurosis of the transverse abdominal muscle. It becomes thin as it ascends to the diaphragm and blends with the fascia covering the under surface of this muscle. It is directly continuous with the iliac fascia, the internal spermatic fascia, and pelvic fasciae. Borders Behind, it is lost in the fat which covers the posterior surfaces of the kidneys. Below, it has the following attachments: posteriorly, to the whole length of the iliac crest, between the attachments of the transverse abdominal an ...

Femoral Sheath
The femoral sheath (also called the crural sheath) is a funnel-shaped downward extension of abdominal fascia within which the femoral artery and femoral vein pass between the abdomen and the thigh. The femoral sheath is subdivided by two vertical partitions to form three compartments (medial, intermediate, and lateral); the medial compartment is known as the femoral canal and contains lymphatic vessels and a lymph node, whereas the intermediate canal and the lateral canal accommodate the femoral vein and the femoral artery (respectively). Some neurovascular structures perforate the femoral sheath. Topographically, the femoral sheath is contained within in the femoral triangle. Structure The femoral sheath is funnel-shaped fascial structure, with the wide end directed superior-ward. The femoral sheath is formed by an inferior-ward prolongation - posterior to the inguinal ligament - of abdominal fascia, with transverse fascia being continued down anterior to the femoral vessels, ...

Pubic Tubercle
The pubic tubercle is a prominent tubercle on the superior ramus of the pubis bone of the pelvis. Structure The pubic tubercle is a prominent forward-projecting tubercle on the upper border of the medial portion of the superior ramus of the pubis bone. The inguinal ligament attaches to it. Part of the abdominal external oblique muscle inserts onto it. The inferior epigastric artery passes between the pubic tubercle and the anterior superior iliac spine. The pubic spine is a rough ridge that extends from the pubic tubercle to the upper border of the pubic symphysis. Clinical significance The pubic tubercle may be palpated. It serves as a landmark for local anaesthetic of the genital branch of the genitofemoral nerve, which lies slightly lateral to the pubic tubercle. This may also be used for the obturator nerve The obturator nerve in human anatomy arises from the ventral divisions of the second, third, and fourth lumbar nerves in the lumbar plexus; the branch from t ...

Pectineal Line (pubis)
The pectineal line of the pubis (also pecten pubis) is a ridge on the superior ramus of the pubic bone. It forms part of the pelvic brim. Lying across from the pectineal line are fibers of the pectineal ligament, and the proximal origin of the pectineus muscle. In combination with the arcuate line, it makes the iliopectineal line The iliopectineal line is the border of the iliopubic eminence. It can be defined as a compound structure of the arcuate line (from the ilium) and pectineal line (from the pubis). With the sacral promontory, it makes up the linea terminalis The ....

Conjoint Tendon
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. Structure The conjoint tendon is formed from the lower part of the common aponeurosis of the abdominal internal oblique muscle and the transversus abdominis muscle. It inserts into the pubic crest and the pectineal line immediately behind the superficial inguinal ring. It is usually conjoint with the tendon of the internal oblique muscle, but they may be separate as well. It forms the medial part of the posterior wall of the inguinal canal. Clinical significance The conjoint tendon serves to protect what would otherwise be a weak point in the abdominal wall. A weakening of the conjoint tendon can precipitate a direct inguinal hernia.

Hernia Repair
Hernia repair refers to a surgical operation for the correction of a hernia—a bulging of internal organs or tissues through the wall that contains it. It can be of two different types: herniorrhaphy; or hernioplasty. This operation may be performed to correct hernias of the abdomen, groin, diaphragm, brain, or at the site of a previous operation. Hernia repair is often performed as an ambulatory procedure. Techniques Inguinal hernia repair The first differentiating factor in hernia repair is whether the surgery is done open, or laparoscopically. Open hernia repair is when an incision is made in the skin directly over the hernia. Laparoscopic hernia repair is when minimally invasive cameras and equipment are used and the hernia is repaired with only small incisions adjacent to the hernia. These techniques are similar to the techniques used in laparoscopic gallbladder surgery. An operation in which the hernia sac is removed without any repair of the inguinal canal is describe ...
