Femoral a.
Femoral v.
Femoral ring
Bounded by medial portion
of inguinal ligament
anteriorly, pectineal
ligament posteromedially,
lacunar ligament medially,
and iliopectinal arch
posterolaterally
Contents:
femoral sheath, femoral a.
and v., genital branch of
genitofemoral n. and
lymphatic vessels, femoral
ring
Femoral triangle 股三角
This triangle is bounded by: the
inguinal ligament (base) superiorly;
the medial border of sartorius
laterally; the medial border of
adductor longus medially. Inferiorly,
the apex of the triangle is
continuous with adductor canal.
The anterior wall is fascia lata
The posterior wall consists of
adductor longus, pectineus and
iliopsoas , from medial to lateral
side.
Contents of the femoral triangle
1. The femoral artery and its
branches-the profunda
femoris artery,The lateral
and medial circumflex arteries,
The deep external pudendal.
2. The femoral vein and its
tributaries.
3. Three or four deep inguinal
lymph nodes lie along the
medial side of the femoral vein.
4. The femoral nerve.
5. The femoral canal.
Femoral sheath 股鞘
The femoral sheath is a a
funnel- shaped sheath ,
derived from transversalis
fascia anteriorly and iliac
fascia posteriorly. It
surroumds the femoral
vessels and lymphatic about
2.5cm belower the inguinal
ligamemt. Its lower end
disappears at the lower
margin of the saphenous
opening where the sheath
fuses with the adventitia of
the vessels.
The femoral sheath is divided into three
compartments by two fibrous septa. The femoral
artery occupies the lateral compartment of the
sheath. The femoral vein lies the middle
compartment. The medial compartment is small,
called the femoral canal.
The femoral canal 股管
It is about 1.3cm long , and its
upper opening is called the
femoral ring 股环.
The boundaries of the
femoral ring are:
inguinal ligament 腹股沟韧带
lacunar ligament 腔隙韧带
pecten of pubis 耻骨梳
femoral vein 股静脉
The canal contains a little
loose fatty tissue, a small
lymph node, and some lymph
vessels.
Femoral hernia 股疝
A femoral hernia is common in women than in men
(possibly due to a wider pelvis and femoral canal ). If a
loop of intestine is forced into the femoral ring, it
expands to form a swelling in the upper part of the thigh.
Adductor canal 收肌管
Extends from apex of femoral
triangle to adductor hiatus
Bounded by vastus medialis
laterally, adductors longus and
magmus posteriorly, and adductor
lamina and sartorius anteriorly
Contents – saphenous nerve,
femoral a., femoral v., lymphatic
vessels, and loose connective
tissue
