Anatomy of Movement Of The Hip - Everything You Need To Know - Dr. Nabil Ebraheim

Dr. Ebraheim’s educational animated video describes the motion of the hip. Muscles and nerves involved in hip motion.

The hip moves in three different planes:
1-Sagittal plane- flexion/extension
2-Frontal plane- abduction/adduction
3-Transverse plane- external/internal rotation
Normal range of the motion of the hip
Flexion-125 degrees
Extension- 10-15 degrees
Abduction 45 degrees
Adduction 30 degrees
External rotation 45 degrees
Internal rotation 40 degrees.
What are the muscles that contributre to hip flexion?
There are three muscle:
1-Iliopsoas
2-Rectus femoris muscle
3-Sartorius muscle
The three muscles are innervated by the femoral nerve. The iliopsoas, rectus femoris and Sartorius muscles are hip flexors and are innervated by the femoral nerve.
What are the muscles that extend the hip?
Two muscles extend the hip
1-Gluteus maximus muscle: innervated by the inferior gluteal nerve
2-Hamstring muscles: innervated by the sciatic nerve.
What muscles abduct the hip?
1-Gluteus minimus muscle
2-Gluteus medius muscle
Both are innervated by the superior gluteal nerve
What are the muscles that adduct the hip?
1-Adductor brevis muscle (Anterior or posterior branch obturator nerve)
2-Adductor longus muscle(Anterior branch obturator nerve)
3-Adductor magnus muscle(posterior branch obturator nerve and sciatic nerve)
4-Gracilis muscle(Anterior branch obturator nerve)
The obturator nerve supplies these four muscles that adduct the hip.
External rotation of the hip
Short external rotators and gluteal muscles. Six short external rotators of the hip :
1-Pirifomis muscle
2-Superior gemellus muscle
3-Obturator internus muscle
4-Inferior gemellus muscle
5-Obturator externus muscle
6-Quadratus femoris muscle.
What are the nerves that supply the six short external rotators of the hip?
The nerve to piriformis innervates the piriformis muscle
The nerve to obturator internus supplies the obturator internus muscle and gemellus superior muscles.
Nerve to obturator externus from the posterior division of the obturator nerve innervates the obturator externus muscle
The nerve to quadratus femoris innervates the quadratus femoris and gemellus inferior muscles.
What two muscles does the nerve to obturator internus innervate?
1-Obturator internus
2-Superior gemellus
What two muscles does the nerve to quadratus femoris innervate?
1-Quadratus femoris
2-Inferior gemellus
Internal rotation
What muscle is the primary internal roattor of the hip?
Gluteus medius muscle: innervated by the superior gluteal nerve.

THANK YOU I CAN'T EXPAIN HOW MUCH THIS HELPED

[sosopinkya]

Dr. Ebraheim, your videos have been of tremendous help. Thank you so much, sir.

[dzonisetac]

At first glance studying human anatomy may appear very difficult. It's true that it's not simple and your studies will not change that. As for being overwhelming, this can be solved if you take your study one step at a time. I found an article on Sebs Study Crammer extremely helpful for this.

[EllOhhVeeE]

Thank you! Although some things appear difficult to learn in the video but the background song soothes and calm me down

[MrEvanston]

.Excellent video!! Wish I could have had when I was in school!!
Thank You Very much.

[HermannTheGreat]

Just excellent. Really helping with my PT learning.

[Unidentifying]

the hip is so complex its pretty mindblowing, with all the combined workings and complementary tissues especially

[nookiebaby]

Your videos are extremely helpful! Please continue to help the medical community!

[nelsonchesterfield]

This video helps a lot! It allows me to understand where is the actual position of these muscle

[meenakothari]

Wow. Too.good. so well.explained . Saved the video.Thankyou

[johnesco]

This video helps me with my latin dance classes!

[daadalamoudi]

THANK YOU SO MUCH, U R SIMPLY AMAZING(( I NEEDED THIS)) U SAVED MY LIFE I CANT THANK U ENOUGH  

[kimjansson]

your channel is so wonderfully informative, thx

[belgas]

🙏❤🙏....thanks for all videos
Avoid hip replacement, check on time muscle, tissue condition. 🙏

[tiberiutomescu]

At the adduction movement lacks the pectineus muscle

[doughnut]

I have a theory that nobody knows exactly how rotation works cuz I searched for more than an hour and watched endless animations but I cant find rotational movement

[julivictoria]

thank you. glad to have your help more than you could know!

[psrathore]

Very well explained Simple and precise Sir

[lagosmaritza]

The content is very good but the music interferes rather then helps. If somebody would keep describing the slides instead of the music playing, it would probably be very powerful. Thanks

[pavanbevoor]

Thanku so much. Pls continue to make such videos.
