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

[@acolley2891]

Thank you. This helped me find a stretch that temporarily eases my nerve entrapment. Such a relief!

[@rudrikthakkar2985]

Concise and very helpful, thank you!

[@robertashaw3523]

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.

[@chengdu2004]

amazing video. nothing could be better than this video to understand femoral nerve injury

[@elizabethsinnott2267]

Wow-eeee, this is an incredible video!! It´s just perfect: thorough, easy to understand, very helpful. Thank you.

[@Txdvsz]

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.

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.

[@anushanimrod5462]

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.

[@andreaskallis9294]

Amazing

Awesome. Thanku

[@krism9292]

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.

Bom dia. Muito grato por suas aulas. Tem me ajudado muito. Uma pergunta: qual tipo de programa usa para fazer essa apresentação.

[@sateeshburada33]

Amazing. Now understand why still struggle with a numbness right knee.

[@615rithiksharma6]

is my injury related to femoral nerve when i have pain in inner portion of thigh just at the starting of leg?

[@mohammedkhan7126]

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

[@dipanshu_goyal_]

0:22 it is pectineus in place of psoas major .....plz correct it

[@beverleywolstenholme5131]

What nerve would be injured during a knee replacement causing foot numbness on lateral side & end 2 toes .. Any thoughts on this please..,

[@springtimesupernova1773]

Shouldn't the Rectus Femoris be included in the hip flexor category?

[@alaudassify9393]

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?

[@geojor]

great information, thank you...

[@TheLawnSensei]

The video is interesting but the music is annoying

[@alexvidu4517]

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.

[@jorgecarrejo7562]

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..

[@mohammadjmohsenkomeylian7278]

Dr.Ebraheim.I have problem with with my back and foot ,today I found out I have femoral nerve problem and I found your video extremely help full. may Allah bless you with your great guidance for free in a society that most people think of money.
Is it possible to give some exercise for this problem.because not all them are use full in TH-cam.

Is it from posterior rami or anterior rami of L2-L4?..

[@thisisbob1001]

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?

[@shiviahuja9840]

This is my issue. Just wish i could see a dr who can tell me exactly what is going on with my pain and discomfort!! Instead of given pills and suffer. I feel like my leg /hip is out of alignment. Thigh is numb. Mp yes but can we fix it. Ugh

[@medfreerecovery3022]

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.
