Q

Discuss the compartments of the femoral sheath

A

Two anteroposterior thin fibrous septa divide the femoral sheath into 3 compartments:
1st/Lateral compartment-contents
(1) common femoral artery-the femoral artery as it enters the thigh beneath the inguinal ligament occupies the lateral compartment of the femoral sheath,i.e.,lies laterally in the femoral sheath
(2) femoral branch of the genitofemoral nerve-pierces the anterior wall of the femoral sheath,running
on the anterior surface of the external iliac artery
2nd/Intermediate(middle)compartment-contents:
common femoral vein-the femoral vein as it leaves the thigh lies medial to the common femoral artery and occupies the intermediate compartment

A

Division of the abnormal band and restoration of the arterial circulation

91
Q

A

Popliteal fossa entrapment

92
Q

Discuss the popliteal fossa entrapment in relation to the adductor canal compression syndrome

A

(1) is the main differential diagnosis

(1) situated at the back of the knee

(2) the popliteal fossa is most prominent when the knee is flexed

97
Q

What is the feature of the popliteal fossa?

A

The popliteal fossa is comparable to the cubital fossa of the upper limb in that both connect the upper and lower segments of the limb

98
