What is the motor function of the femoral nerve?
The femoral nerve is the largest nerve of the lumbar plexus. It forms from the dorsal divisions of the L2-L4 ventral rami.  It has a role in motor and sensory processing in the lower limbs. As a result, it controls the major hip flexor muscles, as well as knee extension muscles.
What does the femoral nerve control?
The femoral nerve is one of the largest nerves in your leg. It’s located near the groin and controls the muscles that help straighten your leg and move your hips. It also provides feeling in the lower part of your leg and the front of your thigh.
What does the femoral nerve innervate?
In the proximal thigh, the femoral nerve divides into sensory branches, which innervate the upper and anterior thigh, and muscular branches, which innervate the quadriceps. One of the major branches is the lateral femoral cutaneous nerve.
What does the femoral nerve turn into?
The femoral nerve is split by the lateral circumflex femoral artery into an anterior and posterior division. These divisions give rise to motor and sensory branches: The motor branches of the femoral nerve are the nerve to pectineus, nerve to sartorius and muscular branches to the quadriceps femoris.
What does femoral nerve pain feel like?
Symptoms may include any of the following: Sensation changes in the thigh, knee, or leg, such as decreased sensation, numbness, tingling, burning, or pain. Weakness of the knee or leg, including difficulty going up and down stairs — especially down, with a feeling of the knee giving way or buckling.
How long does femoral nerve damage take to heal?
Good recovery is achieved in as many as 70% of patients and may take as long as 1 year. Recovery may occur even when the injury is fairly severe, as determined by electrodiagnostic testing and physical examination. Patients with severe axonal loss have some recovery of function, though it is usually incomplete.
How do you free trapped femoral nerve?
Kneeling on one knee, with your foot resting on a chair behind you. Tuck your bottom under and lunge slightly forwards into hip extension. Once you feel a gentle stretch slowly curl your head an upper back down to intensify the stretch for a few seconds then repeat.
How do you fix a pinched femoral nerve?
Femoral Neuropathy Treatment Your doctor may recommend physical therapy or splints or other assistive devices to make walking easier and safer. If you have a tumor or other type of growth causing compression of the nerve, your doctor may recommend surgery to remove it and relieve the pressure.
Can a damaged femoral nerve be repaired?
In some cases, the nerve will heal with treatment of the underlying medical problem. Other treatments may include: Surgery to remove a tumor or growth that is pressing on the nerve. Medicines to relieve pain.
Why is femoral nerve pain worse at night?
At night our body temperature fluctuates and goes down a bit. Most people tend to sleep in a cooler room as well. The thought is that damaged nerves might interpret the temperature change as pain or tingling, which can heighten the sense of neuropathy.
What can you do for a pinched femoral nerve?
Some treatments of femoral neuropathy include:
- Medication. A doctor may prescribe corticosteroids to reduce inflammation and swelling.
- Surgery. If a growth or tumor is blocking the femoral nerve, a doctor might recommend surgery to remove it.
- Lifestyle remedies.
- Physical therapy.
What does a pinched femoral nerve feel like?

What action does the femoral nerve do?
The femoral nerve is one of the major nerves that innervates the legs. Its principal function is to carry instructions to the muscles that straighten the leg , such as the quadriceps, found in the anterior thigh.
What are the symptoms of femoral nerve damage?
Symptoms of femoral nerve damage range from a feeling of general weakness in the leg to prickly sensations. It may sometimes be difficult to walk or stand for long periods of time. Often, patients describe feeling as though the knee simply collapses, especially when attempting to use stairs.
What is the origin of the femoral nerve?
The femoral nerve is the largest nerve that originates from the lumbar spine from three vertebrae: L2, L3, and L4. Its complicated path takes it through the psoas muscle. This muscle is located behind the organs but in front of the spine, deep inside the body.
What are femoral nerves?
Femoral Nerve. The femoral nerve is the major nerve that serves the tissues of the thigh and leg, including the muscles and skin. While the much larger sciatic nerve also passes through the thigh on its way to the lower leg and foot, only the femoral nerve innervates the tissues of the thigh.
