What is the mnemonic navel used for?
The well-described NAVEL mnemonic (see the image below) has been used to help medical students and surgical trainees remember the relationship of the femoral sheath structures in a lateral-to-medial direction: femoral Nerve, femoral Artery, femoral Vein, Empty space, and Lymphatics.
How do you remember the femoral triangle?
As well as these boundaries, the femoral triangle also has a floor and a roof. The floor is comprised of four muscles that can be easily remembered by using the mnemonic APPI (adductor longus, pectineus, psoas major and illiacus muscles).
Where is femoral triangle?
The femoral triangle is a hollow region located in the supero-medial part of the anterior thigh. It appears most prominently with hip flexion, abduction and internal rotation. It is an easily accessible area through which multiple neurovascular structures pass through.
What is contained in femoral sheath?
The three compartments of the femoral sheath include: The lateral compartment, which contains the femoral artery and femoral branch of genitofemoral nerve. The middle compartment, which contains the femoral vein. The medial compartment, where the femoral canal and lymphatics course through.
How do you remember the branches of the femoral artery?
- P: profunda femoris (deep femoral artery)
- M: medial circumflex femoral artery.
- L: lateral circumflex femoral artery.
- D: descending branch of the lateral circumflex femoral artery.
- P: perforating arteries.
What is the adductor hiatus?
The adductor hiatus (AH) can be described as an opening in the aponeurotic distal attachment of adductor magnus muscle, which transmits the femoral artery and vein from the adductor canal in the thigh to the popliteal fossa (1). The majority of femoropopliteal occlusions are located distally in the thigh (3–7).
What is the adductor canal?
The adductor canal is a narrow fascial tunnel in the thigh, providing an intramuscular passage through which the femoral artery and vein pass into the popliteal fossa of the knee (Fig. 5.15).
How do you palpate a femoral ring?
Press deeply, below the inguinal ligament and about midway between symphysis pubis and anterior superior iliac spine. Use two hands one on top of the other to feel the femoral pulse.
