Femoral Nerve Anatomy - Everything You Need To Know - Dr. Nabil Ebraheim
Dr. Ebraheim’s educational animated video describes the anatomy of the femoral nerve in a very easy and simple animation.
The femoral nerve arise from L2, L3, and L4 posterior divisions of the ventral rami. The anterior division of the ventral rami gives the obturator nerve. The femoral nerve is the largest branch of the lumbar plexus. The two muscular branches of the femoral nerve supply the psoas and iliac muscle (iliopsoas). the femoral nerve descends from the lumbar plexus in the abdomen through the psoas major muscle. The nerve then passes deep to the inguinal ligament where it then enters the femoral triangle of the thigh. Inside the femoral triangle, the nerve is lateral to the femoral artery. Distal to the inguinal ligament and under the Sartorius' muscle, the femoral nerve splits into the terminal branches. The branches are motor and sensory.
•Motor branches to Sartorius, Quadriceps and Pectineus.
•Sensory branches: intermediate femoral cutaneous nerve, saphenous nerve, medial femoral cutaneous nerve.
Motor function of the femoral nerve
Hip flexors
•Iliacus
•Psoas
•Pectineus
•Sartorius
Knee extensors
•Quadriceps femoris (includes four muscle): vastus lateralis, vastus intermedius, vastus medialis, rectus femoris (superficial layer).
The function of the femoral nerve is to provide motor innervation for the muscles that allow for flexion of the hip and extension of the knee.
Testing the motor functions of the femoral nerve: the function of the quadriceps muscle can be assessed with the patient being seated, the examiner applies resistance against leg extension. The function of the iliopsoas muscle can be tested by having the patient flex the hip against resistance.
Femoral nerve involvement, injury or palsy
Usually caused by trauma.
The manifestation of femoral nerve injury:
•Wasting of the quadriceps femoris
•Loss of knee extension
•Some loss of hip flexion (iliacus & psoas)
Differential diagnosis:
•Quadriceps tendon rupture
Other areas of interest for involvement of the femoral nerve
•Lumbar spine (lumbar disc herniation)
•Pelvis (pelvic hematoma)
Clinical evaluation of L4 nerve root
•Sensory area of L4
•L4: dorsiflexion of the ankle (tibialis anterior)
•Patellar reflex ( L2, L3, L4): the patellar reflex is mainly L4
•Femoral stretch test: positive test means the L3, L4 nerve roots are involved. Most disc herniations affect the L5-S1 nerve roots (use straight leg raise test). The test will stretch the femoral nerve and is positive when pain is felt on the ipsilateral anterior thigh.
The femoral nerve (saphenous nerve) may be affected with hematoma of the pelvis.
Muscles within iliopsoas compartment:
•Iliacus
•Psoas major
•Psoas minor
Hemorrhage in the pelvis and iliopsoas hematoma may usually be caused by
•Severe trauma
•Anti coagulation therapy
•Hemophilia or other blood diseases.
Clinical presentation: paresthesia around the medial side of the knee in the distribution of the saphenous nerve.

Thank you very much doctor, especially for including the effect of nerve injury! So educational and easy to follow
Thank you. This helped me find a stretch that temporarily eases my nerve entrapment. Such a relief!
amazing video. nothing could be better than this video to understand femoral nerve injury
awesome, thank you so much for this video, it has helped me to understand how a herniated disk can effect ones movement and the pain that is associated with your sudden back pain. thank you.
thanks
Wow-eeee, this is an incredible video!! It´s just perfect: thorough, easy to understand, very helpful. Thank you.
Thank you SO much for this. I have been having terrible groin pain and SI joint pain. this explains a lot!!
Concise and very helpful, thank you!
My god.. I absolutely love you. Your videos are my only saving grace for MSK block. God bless you!
Incredible, thank you Dr Ebraheim
Excellent video to follow and understand the thigh muschles.
Well informative and pretty useful , thank you so much Dr Nabil
Thanks dr for posting such an important information.
Thanks you. This information was very helpful. I relayed this information to my Orthopedic doctor on the first visit and the MRI confirmed bulging discs and bone degradation from aging. It's very helpful to the doctor if the patient is well informed and able to communicate the symptoms.
Great information about the Femoral Nerve Thank You
Thank-you. This and another's video did what Doctors weren't able to do for 4 months! Leg pain is gone, at least for the time being!

Leg and back pain.... What video exercises did you do? Thanks
best presentation I have ever seen thanks
How is anyone able to read and conceptualize looking at the imagery that fast...I sure as hell cant, geesh.
thank you so much doctor..really appreciate your effort.. such an amazing video.! really marvelous! a piece of art. ^_^
Bom dia. Muito grato por suas aulas. Tem me ajudado muito. Uma pergunta: qual tipo de programa usa para fazer essa apresentação.
Excellent video
So good! Thank You!
Thank you so much for the tutorial. =)
Great video Thanks
Thank u so much!!! The medial margin of femoral triangle should be corrected. In the video, it is shown as the lateral margin of adductor longus. But it should be its medial margin, because adductor longus is taken as a muscle that is inside the femoral triangle.
is my injury related to femoral nerve when i have pain in inner portion of thigh just at the starting of leg?
Well done doctor 👍🙏🙏🙏
one of the best video
These are advanced medical terminologies, the Dr knows his business, great video thank you; although all I have is CXC Biology I love videos of the human anatomy & science videos in general.

Sir I saw this video it is very informative but I have one question I also have numbness and less sensitivity around me knees can you suggest me which doctor is suitable for treatment like general phycian or any specialist for this problem
Amazing. Now understand why still struggle with a numbness right knee.
Awesome. Thanku
excuse me sir can this technique applied for the polio patient leg muscles ? plz kindly give me ans ? aur totall expenses ktny hon gy ?
Thanks
Thanks alot
Shouldn't the Rectus Femoris be included in the hip flexor category?
you Dr. having made sense of what doctors call psychological I have been in the worst pain after an accident months ago. They stated to do PT did nothing until it made the pain worse.I had an EMG even after that the dr. never told me of signs and symptoms. Just maybe in two years you can walk again??? I love you DR. this is on par to saving my life, now I will present my problems made clear here to dr.s Thank from all my heart.
Thankyou sir
What nerve would be injured during a knee replacement causing foot numbness on lateral side & end 2 toes .. Any thoughts on this please..,
The video is interesting but the music is annoying

Thanks for the Video! Forgive me for chiming in, I am interested in your thoughts. Have you ever tried - Taparton Sturdy Nerves Takeover (probably on Google)? It is an awesome one of a kind product for Getting rid of Neuropathy minus the normal expense. Ive heard some pretty good things about it and my cousin at last got cool success with it.
Great animation to understand the femoral nerve better. Thank you very much. The infinite loop of synthesizer music however is unbearable (strenuous, as it begins again and again without a smooth transition). A different background music, if it all, would be greatly appreciated.

Hello, can a femoral nerve injury heal and what is the recovery time?
0:22 it is pectineus in place of psoas major .....plz correct it
great information, thank you...
Very good educational video. The music is annoying. INDEED. Desde aquí desde Estados Unidos.
Is it from posterior rami or anterior rami of L2-L4?..
great
anyone know how deep the nerves are? I put my cgm on my thigh and now I feel a burning sensation when I get up to walk..
I have a question based on divisions of anterior rami of plexus(both lombar and brachial). I does not understand what means the divisions and what are their purposes, if can someone explain i would be gratefull!!
Hi, I'm 49 and in good health and weight. 3 months ago I had increasingly pain at my lower back that came on over a couple of days. It was the worst pain ever and could not even move in bed for over a week. It has reduced to lesser pain now but still very painfully from left hip and groin area down front of my thigh to bottom of knee cap and to ankle. I'm on pain killers naproxen, gabapentin and codeine which takes the edge off it. I often end up being bent over because of pain and sometimes my leg gives way. What is causing this constant pain and how can I cure it please?

If you actually would like to have the root problem of your issue solved I'd like to recommend to see a physiotherapist or a chiropractor.
