- Anatomy:
- arises from posterior divisions of Ventral Rami of
L2,
L3,
L4
- see
innerv. musc. lower limb;
- passes inferolaterally thru
psoas, & then runs between this muscle &
iliacus;
- it passes over
Iliacus muscle to enter thigh underneath the inguinal ligament;
- it supplies
quadriceps & anteromedial thigh, & then continues on as the
saphenous nerve;
- branches:
-
Pectineus : arises at the level of the inguinal ligament;
-
Sartorius
-
Quadriceps
- Femoral Nerve Block:
- Femoral Nerve Palsy:
- may result from iliacus hematoma (either from anticoagulation or hemophilia);
Femoral nerve block
in knee joint surgery.
Iatrogenic femoral nerve injuries.
Ipsilateral sciatica on femoral nerve stretch test is pathognomonic of an L4/5 disc protrusion.
