The pectineal ligament, sometimes known as the inguinal ligament of Cooper, is an extension of the lacunar ligament. It runs on the pectineal line of the pubic bone. The pectineal ligament is the posterior border of the femoral ring.
The pectineal ligament connects to the lacunar ligament, and therefore to the inguinal ligament. [1] It connects to the pectineus muscle on its ventral and superior aspects. [1] It connects to the rectus abdominis muscle, and the abdominal internal oblique muscle, of the anterior abdominal wall. [1]
The pectineal ligament is usually around 6 cm long in adults. [2] It is close to the major vasculature of the pelvis, including external iliac vein. [2]
The pectineal ligament is strong, and holds suture well.[ citation needed ] This facilitates reconstruction of the floor of the inguinal canal.[ citation needed ] It is a useful landmark for pelvic surgery. [1] A variant of non-prosthetic inguinal hernia repair, first used by Georg Lotheissen in Austria, now bears his name.[ citation needed ]
The pectineal ligament was characterized by Astley Cooper in 1804. [3] [4]
A hernia is the abnormal exit of tissue or an organ, such as the bowel, through the wall of the cavity in which it normally resides. The term is also used for the normal development of the intestinal tract, referring to the retraction of the intestine from the extra-embryonal navel coelom into the abdomen in the healthy embryo at about 7½ weeks.
The inguinal canal is a passage in the anterior abdominal wall on each side of the body, which in males, convey the spermatic cords and in females, the round ligament of the uterus. The inguinal canals are larger and more prominent in males.
An inguinal hernia or groin hernia is a hernia (protrusion) of abdominal cavity contents through the inguinal canal. Symptoms, which may include pain or discomfort especially with or following coughing, exercise, or bowel movements, are absent in about a third of patients. Symptoms often get worse throughout the day and improve when lying down. A bulging area may occur that becomes larger when bearing down. Inguinal hernias occur more often on the right than left side. The main concern is strangulation, where the blood supply to part of the intestine is blocked. This usually produces severe pain and tenderness of the area.
The transverse abdominal muscle (TVA), also known as the transverse abdominis, transversalis muscle and transversus abdominis muscle, is a muscle layer of the anterior and lateral abdominal wall, deep to the internal oblique muscle. It is thought by most fitness instructors to be a significant component of the core.
The abdominal external oblique muscle is the largest and outermost of the three flat abdominal muscles of the lateral anterior abdomen.
In human anatomy, the inferior epigastric artery is an artery that arises from the external iliac artery. It is accompanied by the inferior epigastric vein; inferiorly, these two inferior epigastric vessels together travel within the lateral umbilical fold The inferior epigastric artery then traverses the arcuate line of rectus sheath to enter the rectus sheath, then anastomoses with the superior epigastric artery within the rectus sheath.
In vertebrates, the pubis or pubic bone forms the lower and anterior part of each side of the hip bone. The pubis is the most forward-facing of the three bones that make up the hip bone. The left and right pubic bones are each made up of three sections; a superior ramus, an inferior ramus, and a body.
The conjoint tendon 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 obturator artery is a branch of the internal iliac artery that passes antero-inferiorly on the lateral wall of the pelvis, to the upper part of the obturator foramen, and, escaping from the pelvic cavity through the obturator canal, it divides into an anterior branch and a posterior branch.
In human anatomy, the inguinal region refers to either the groin or the lower lateral regions of the abdomen. It may also refer to:
A Spigelian is the type of ventral hernia where aponeurotic fascia pushes through a hole in the junction of the linea semilunaris and the arcuate line, creating a bulge. It appears in the lower quadrant of the abdomen between an area of dense fibrous tissue and abdominal wall muscles causing a.
Femoral hernias occur just below the inguinal ligament, when abdominal contents pass through a naturally occurring weakness in the abdominal wall called the femoral canal. Femoral hernias are a relatively uncommon type, accounting for only 3% of all hernias. While femoral hernias can occur in both males and females, almost all develop in women due to the increased width of the female pelvis. Femoral hernias are more common in adults than in children. Those that do occur in children are more likely to be associated with a connective tissue disorder or with conditions that increase intra-abdominal pressure. Seventy percent of pediatric cases of femoral hernias occur in infants under the age of one.
The transversalis fascia is the fascial lining of the anterolateral abdominal wall situated between the inner surface of the transverse abdominal muscle, and the preperitoneal fascia. It is directly continuous with the iliac fascia, the internal spermatic fascia, and pelvic fascia.
The femoral ring is the opening at the proximal, abdominal end of the femoral canal, and represents the base of the conically-shaped femoral canal. The femoral ring is oval-shaped, with its long diameter being directed transversely and measuring about 1.25 cm. The opening of the femoral ring is filled in by extraperitoneal fat, forming the femoral septum.
The femoral canal is the medial compartment of the three compartments of the femoral sheath. It is conical in shape. The femoral canal contains lymphatic vessels, and adipose and loose connective tissue, as well as - sometimes - a deep inguinal lymph node. The function of the femoral canal is to accommodate the distension of the femoral vein when venous return from the leg is increased or temporarily restricted.
The lacunar ligament, also named Gimbernat's ligament, is a ligament in the inguinal region. It connects the inguinal ligament to the pectineal ligament, near the point where they both insert on the pubic tubercle.
In human anatomy, the median umbilical ligament is an unpaired midline ligamentous structure upon the lower inner surface of the anterior abdominal wall. It is covered by the median umbilical fold.
The aponeurosis of the abdominal external oblique muscle is a thin but strong membranous structure, the fibers of which are directed downward and medially.
Georg Lotheissen was an Austrian surgeon born in Geneva, Switzerland.
Inguinal hernia surgery is an operation to repair a weakness in the abdominal wall that abnormally allows abdominal contents to slip into a narrow tube called the inguinal canal in the groin region.
