Obturator Nerve Anatomy - Everything You Need To Know - Dr. Nabil Ebraheim

Dr. Ebraheim’s educational animated video describes the anatomy of the Obturator nerve.
The obturator nerve is the second major nerve that arises from L2, L3 and L4 ventral rami of the lumbar plexus. The obturator nerve travels under the psoas major muscle and lies on the medial side of the psoas major. The obturator nerve then runs between the psoas and iliacus muscles through the pelvis towards the obturator foramen. The obturator foramen is covered by the obturator membrane.
The obturator externus muscle arises from the obturator membrane. Structures that run under the inguinal ligament:
The obturator canal is an opening in the obturator membrane at its superior lateral aspect. The obturator nerve is accompanied with vessels that exit the pelvis through the obturator canal. The obturator nerve and artery are at risk of injury from the placement of a retractor beneath the transverse acetabular ligament.
With an “open book” reduction, the reduction clamp is usually inserted through the medial side of the foramen away from the neurovascular bundle. Outside the foramen in the proximal part of the thigh, the obturator nerve divides into anterior and posterior divisions. The anterior division passes in front of the abductor brevis muscle and the posterior division passes behind the muscle.
Branches
Anterior division
•Adductor brevis
•Adductor longus
•Sensory branch
•Gracilis
Posterior division
•Obturator externus
•Adductor Magnus
One-third of the population will have an accessory obturator nerve arising from L3-L4. The accessory obturator nerve passes over the superior pubic rami and then dives below the pectineus muscle and joins the anterior division of the obturator nerve. The accessory obturator nerve supplies the pectineus muscle which is usually innervated by the femoral nerve.
Test for obturator nerve- adductor muscle assessment
While in a sitting position, the examiner has the patient squeeze the thighs with resistance placed at the inside of the knees. Weak thigh adduction indicates obturator nerve injury.

MashaAllah your videos are really informative and very good to follow. LOVE to study with them, Thank you very much.

[@tem1465]

I needed a quick revision of the obturator nerve anatomy for a patient I am suspecting Obturator nerve entrapment....and this video gave me just exactly what I was looking for. Thanks for your work.

[@NicoProv]

I also suspect obturator nerve entrapment on myself. My lower back, groin( testicles) , and down my inner front left thigh are in pain for about 8 months now. They felt better the last month and a half but just started up last week again and it's painful. Can I ask you if you were able to help the patient fix that issue and how so? I saw a video on obturator nerve flossing. I will try that. I've done lots of stretches for the lower back thinking a disc was bulging and pinching a nerve. Maybe it's a tight psoas or Iliac muscle. I'm not sure now.

Thank you so much. I hope you are you doing well, especially during these times. All the best to you.

[@luziqa4046]

your videos are really informative !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! and well ilustrated!

[@geojor]

another informative video, thank you...

[@DollyGarlo]

This was very helpful. Thank you.

[@mesozoicperiodvlogs8323]

These videos are fantastic, i love the music you selected. It adds a very relaxing feel to these videos. I am only disappointed in my anatomy course, they aren’t giving us enough time to go into all these fantastic details you are covering.

[@nancyibraham7245]

Great video , thanks

[@SunPing32]

Wonderful Information!!! ThankYou Very Much!!!!

[@pragatitiwari9700]

excellent video. pls upload more videos

[@akhilchouhan3176]

Amazing method

[@DrMVSrinivas]

Million thanks for ur work... U wont feel fatigue at al SIR

[@raginiepte2152]

Ty for taking efforts to upload dis video...ty;-)

[@kathys5176]

Trying to narrow down very painful inner thigh spasms, had them since 2011. Horrible pain, thought it was adductors first. Now I think its the gracilis, thank you for the info, I'm just looking at all possibilities. Best regards. Kathy

[@janezkolar]

Kathy, hi! I have jad these painful spasms for some years also. Did you find any cure or solution for this?

[@gendennyamtsoo7551]

Thank you doctor.

[@gendennyamtsoo7551]

Very helpful information.

[@drdmm]

This is the best and exactly what I’m looking for

[@believer8491]

Bundles of thanksss!!SIR.

[@jangadzahir3089]

Sir you have written abductor insted of adductor brevis in theory

[@msme9790]

perfect!

[@kenzasadaoui7091]

Oh thnk youuuuu

[@inviktus3349]

2:20 the muscle is "adductor" brevis and not abductor

[@farhatanjum9246]

Tnx sir

[@kaypolo]

I've been in pain for a long time and I got a feeling that this may be my problem. (entrapment/irritation)

[@edotensei5083]

I hope you’re good now

[@pushtoon2469]

Sir at 2:23 its adductor brevis not abductor

[@rawandspicy]

ADDuctor not ABDuctor brevis 2:24 Typo

[@tem1465]

Mariangel Reyes I didn't see it.... I think because I had adductor in my mind through and through. Had to go back and confirm your comment... Hahahaha.

[@user-po6cn3gf5k]

2 : 21 Did you mean adductor brevis ?

[@dr.renukantlokre2228]

Psoas and iliacus vessels

[@umapriyaiyyappadasan6198]

well

[@brendahines4153]

Fuck my nerves!!!

[@anjaligupta-jj9fn]

thanks
