Areas of fascial weakness or non-union at the site of a prior surgical incision can result in what type of hernia?
|
Incisional hernia
|
|
|
What is the most common type of groin hernia?
|
Groin hernias are the most comon type of abdominal hernia. Indirect inguinal hernias are the predominant type, followed by direct, then femoral.
|
|
|
The abdominal wall is made up of what 3 musculoaponeurotic layers, from superficial to deep?
|
External Oblique, internal oblique, transversus abdominus
|
|
|
The external oblique arises from the ______ ribs, interdigitates with the ________ and _______ muscles. It's fibers run in which direction?
|
Lower 8 ribs
Serratus Anterior Latissimus Dorsi Inferomedial |
|
|
What forms the inguinal ligament?
|
The portion of the external oblique between the pubic tubercle and ASIS, which is somewhat thickened and folds back on itself forming the inguinal (or Poupart's) ligament.
|
|
|
Medially, the inguinal ligament reflects back onto the pectin pubis as what structure?
|
Lacunar Ligament
|
|
|
The superficial inguinal ring is an opening in which aponeurosis? Where is the superficial inguinal ring, in relation to the inguinal ligament?
|
External Oblique
Just superior to the medial portion of the inguinal ligament. |
|
|
What are the 9 layers, from superficial to deep, of the anterior abdominal wall?
|
Skin
Subcutaneous fat Scarpa fascia External oblique muscle Internal Oblique Muscle Transversus abdominus muscle Transversalis fascia (endoabdominal fascia Properitoneal fat Peritoneal fat |
|
|
What structures exit the inguinal canal through the superficial inguinal ring?
|
Men- Spermatic Cord
Women- Round ligament |
|
|
What direction do the fibers of the internal oblique muscle run?
|
Superomedial. It also serves as the superior border of the inguinal canal
|
|
|
What forms the conjoint tendon?
|
Aponeurosis of the internal oblique joined with the aponeurosis of the transversus abdominus
|
|
|
The aponeurosis of the internal oblique contributes to which portion of the rectus sheath, anterior or posterior?
|
Above the arcuate line: Both anterior and posterior rectus sheath (until the posterior sheath ends inferiorly)
Below the arcuate ligament: anterior rectus sheath only. |
|
|
What direction does the transversus abdominus course?
|
Transverse. Above the arcuate line, the aponeurosis contributes to he posterior rectus sheath along with the internal oblique. Below the arcuate line, it joins the intern and external oblique to form the anterior rectus sheath.
|
|
|
The transversus abdominus aponeurosis inserts into this structure, which is formed of periosteum and fascial condensations along the posterior aspect of the superior pubic ramus.
|
Cooper's Ligament.
|
|
|
Through what structure do the spermatic cord and round ligament exit the abdominal cavity?
|
Deep inguinal ring. This is where they enter the inguinal canal. They exit the inguinal canal through the superficial inguinal ring.
|
|
|
The deep inguinal ring is a defect in which structure?
|
Transversalis fascia. It is approximately half way between the ASIS and pubic tubercle.
|
|
|
What forms the falx inguinalis?
|
Arching fibers of the internal oblique and transversus abdominis muscles, which forms the superior border of the inguinal canal.
