inguinal ligament

Examples of inguinal ligament in the following topics:

• Lumbar Plexus

  • The largest nerve of the plexus is the femoral nerve and it supplies the anterior muscles of the thigh and a part of skin distal to the inguinal ligament.
  • Its terminal branch then runs parallel to the inguinal ligament to exit the aponeurosis of the abdominal external oblique above the external inguinal ring, where it supplies the skin above the inguinal ligament (i.e., the hypogastric region) with the anterior cutaneous branch.
  • The lateral femoral branch is purely sensory and pierces the vascular lacuna near the saphenous hiatus and supplies the skin below the inguinal ligament.
  • In females, it runs in the inguinal canal together with the teres uteri ligament.
  • Medial to the anterior superior iliac spine, it leaves the pelvic area through the lateral muscular lacuna and enters the thigh by passing behind the lateral end of the inguinal ligament.

• Veins of the Abdomen and Pelvis

  • The deep circumflex iliac vein is formed by the union of the venae comitantes of the deep iliac circumflex artery, and joins the external iliac vein about 2 cm above the inguinal ligament.

• Inguinal Hernia

  • An inguinal hernia is a protrusion of abdominal-cavity contents through the inguinal canal.
  • An inguinal hernia is a protrusion of abdominal-cavity contents through the inguinal canal .
  • The hernia truss is intended to contain a reducible inguinal hernia within the abdomen.
  • Surgical correction of inguinal hernias is called a hernia repair.

• Uterine Prolapse

  • Uterine prolapse occurs when the ligaments supporting the uterus become so weak that the uterus slips down from its normal position.
  • The uterus is normally held in place in the lower pelvis by a hammock of muscles and ligaments called the pelvic floor.
  • The ligaments of the pelvic floor are the round ligament, uterosacral ligaments, broad ligament, and the ovarian ligament.
  • The utereosacral ligaments are by far the most important ligaments holding the uterus in place.
  • Prolapse occurs when these ligaments that support the uterus become so weak that the uterus cannot stay in place and slips down from its normal position, protruding into or outside of the vagina.

• Cryptorchidism

  • In 90% of cases an undescended testis can be palpated in the inguinal canal; in the minority, the testis or testes are in the abdomen or nonexistent (truly "hidden").
  • Undescended testes are also more susceptible to testicular torsion and infarction, and inguinal hernias.
  • When the undescended testis is in the inguinal canal, hormonal therapy is sometimes attempted and occasionally successful.
  • Although many trials have been published, the reported success rates range widely, from roughly 5 to 50%, probably reflecting the varying criteria for distinguishing retractile testes from low inguinal testes.

• Syndesmoses

  • Syndesmoses are slightly movable joints formed where an interosseous ligament joins two bones.
  • The anterior inferior tibiofibular ligament crosses in front of the tibia and fibula bones.
  • The posterior inferior tibiofibular ligament and the transverse ligament connect the two bones from behind, and the interosseous ligament runs between the contiguous bony surfaces of the two bones.
  • Mild syndesmosis injury may involve the sprain of a single ligament.
  • When that happens, the surgeon temporarily replaces the ligament with a syndesmotic screw.

• Pulled Groin

  • In human anatomy, the groin (the adjective is inguinal, as in inguinal canal) areas are the two creases at the junction of the torso with the legs, on either side of the pubic area.

• Pubis

  • This tubercle, found roughly 3 cm from the pubic symphysis, is a distinctive feature on the lower part of the abdominal wall and is useful when attempting to localize the superficial inguinal ring and the femoral canal of the inguinal canal.

• Bursae and Tendon Sheaths

  • Synovial joints are made up of five classes of tissues: bone, cartilage, synovium, synovial fluid, and tensile tissues composed of tendons and ligaments.
  • Tendons are similar to ligaments and fasciae as they are all made of collagen, but a ligament joins one bone to another and fasciae connect muscles to other muscles.
  • For example, to protect the knee and reduce friction from the various muscles, tendons, and ligaments that attach to and cross the knee joint, knees are cushioned by 14 different bursae: five in front, four laterally, and five medially.

• Arches of the Feet

  • The two longitudinal arches and a transverse arch are maintained by the interlocking shapes of the foot bones, strong ligaments, and pulling muscles during activity.
  • Excessive strain on the tendons and ligaments of the feet can result in fallen arches or flat feet.
  • Its weakest part (i.e., the part most liable to yield from too much pressure) is the joint between the talus and navicular, but this portion is braced by the plantar calcaneonavicular ligament, also called the spring ligament, which is elastic and is thus able to quickly restore the arch to its original condition when the disturbing force is removed.
  • The ligament is strengthened medially by blending with the deltoid ligament of the ankle joint, and is supported inferiorly by the tendon of the tibialis posterior, which is spread out in a fan-shaped insertion and prevents undue tension of the ligament or such an amount of stretching as would permanently elongate it.
  • Two strong ligaments—the long plantar and the plantar calcaneocuboid—the extensor tendons, and the short muscles of the little toe preserve its integrity.
