The femoral nerve is one of the significant fringe nerves of the lower appendage. The femoral nerve is basic for exercises of day by day life including strolling and climbing stairs. Without it, the lower appendage turns out to be extremely debilitated. In this article we will talk about its course, its engine and tactile innervation and in addition clinical pertinence.
In this article, we will take a gander at the life structures of the femoral nerve – its anatomical course, engine, and tactile capacities, and any clinical importance.
The nerve slides from the lumbar plexus in the belly, going down through the filaments of psoas major. The nerve exits psoas major at the lower some portion of its sidelong outskirt, going behind the iliac belt to around the mid-purpose of the inguinal tendon. It at that point crosses behind the inguinal tendon into the thigh and parts into a foremost and back division.
It goes through the femoral triangle parallel to the femoral vessels (encased inside the femoral sheath) and radiates articular branches to the hip and knee joints.
The terminal cutaneous branch of the femoral nerve is the saphenous nerve which proceeds, with the femoral supply route and vein, through the adductor waterway.

Engine Functions of femoral nerve
The femoral nerve supplies a portion of the muscles of the foremost thigh
Pectineus – adducts and flexes the thigh, helps with the average revolution of the thigh.
Iliacus – acts with psoas major and psoas minor (shaping iliopsoas) to flex the thigh at the hip joint and balance out the hip joint.
Sartorius – flexes, snatches and horizontally turns the thigh at the hip joint. Flexes the leg at the knee joint.
Quadriceps femoris (rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius) – broadens the leg at the knee joint. Rectus femoris likewise steadies the hip joint and helps iliopsoas in flexing the thigh.
Signs or Symptoms of femoral nerve lesion
- Quadriceps muscle shortcoming and squandering.
- Loss of knee twitch.
- Deadness along the average side of the thigh and anteromedial side of the calf (the L2-L4 dermatomes – see figures underneath).
- Agony on hip expansion (in instances of retroperitoneal haematoma).
- In one little investigation after a gynecological medical procedure, the finding was made in light of the accompanying criteria
- History of falling amid postoperative ambulation.
- Quadriceps shortcoming.
- Straight leg raises shortcoming.
- Decreased automatic reaction.
- No proof of psoas hematoma or ulcer.

Treatment of femoral nerve
Your supplier will endeavor to distinguish and treat the reason for the nerve harm. You’ll be dealt with for any medical issues, (for example, diabetes or seeping in the pelvis) that might cause the nerve harm. Now and again, the nerve will mend with a treatment of the basic therapeutic issue.
Different medications may include:
A medical procedure to evacuate a tumor or development that is pushing on the nerve.
Solutions to ease torment:
Weight reduction and change in way of life if diabetes or overabundance weight is adding to the nerve harm.
Now and again, no treatment is required and you’ll recuperate individually. Assuming this is the case, any treatment, for example, non-intrusive treatment, is gone for expanding versatility, keeping up muscle quality, and freedom while you recoup. Supports or braces might be recommended to help in strolling.
