TTTT
In femoral hernia, the hernial sac (F/F)
passes behind the inguinal ligament.
Passes medial to the femoral vein.
Passes anterior to the superior pubic ramus.
Is covered by the fascias of the femoral septum and the cribriform fascia.
Contains a large quantity of fat.
TTTTT
The sac of a femoral hernia passes behind the inguinal ligament (1 true) into the femoral canal, which lies medial to the femoral vein and anterior to the superior pubic ramus. (2 & 3 true). The sac enters the femoral canal through its upper opening -the femoral ring. This is normally closed by the femoral septum, a fusion of iliopectineal fascia behind and transversalis fascia anteriorly. The sac, covered by extraperitoneal fat and femoral septum fascia, leaves the femoral canal to enter the subcutaneous tissues of thigh and groin, by passing anteriorly through the fossa ovalis and its overlying cribriform fascia. (4 true). The sac of a femoral hernia thus contains several fascial layers separated from each other by fat. A large portion of the sac is fatty (5 true) which can make the cough impulse of a femoral hernia less obvious.
Femoral hernia is (T/F)
1: More common in female than in male patients.
More common than inguinal hernia in female patients.
Able to be controlled by the wearing of a hernia truss.
Classically associated with strangulation bowl obstruction of Richter type.
More prone to recurrence after surgery than is inguinal hernia.
TFFTF
Femoral hernia is more common in females than in males (1 true). You would need to go back further to find the records of 100 femoral hernia repairs, because femoral hernias are much less common than are inguinal hernias. But there would be a majority of females in your group. The femoral ring and canal are wider in females than males, in keeping with the wider female pelvis. Inguinal hernias outnumber femoral in women as well as in men (2 false). Thus if you identify a groin hernia and you cannot be sure of the clinical diagnosis in a male, the odds on it being inguinal are quite high. In a woman under the same circumstances the hernia is also more likely to be inguinal, but the odds will not be so great. For most hernias, a truss is not a reliable method of control. The hernia must be reducible and the truss needs to control the defect and prevent the hernia escaping. If the hernia does protrude while a truss is worn, the effectiveness of the truss is lost and the risk of strangulation increased. A truss might be occasionally helpful in an infirm patient when the mouth of the hernial sac is wide, the hernia is easily reducible and the risk of strangulation considered low. Femoral hernias have a small neck and a tortuous sac pathway and are particularly unsuited to truss use (3 false). Response 4 is true and 5 false (see X1).
