Posterior Hip Muscles: Video #13 of Introduction to Functional Anatomy

This video introduces viewers to the posterior hip muscles, which are integral for stabilizing the hip joint and providing power to the lower body for movement. These muscles play an important role in activities like walking, running, and jumping, and it's important to understand their anatomy and role in biomechanics. Learn about hip anatomy and biomechanics to improve your athletic performance and rehabilitation program.

You're about to like the glutes a lot

00:00:0600:00:17

too, oh boy. Right so glutes, glutes have a

00:00:1700:00:25

huge, huge origin right. They go all posterior ilium, all the way down the

00:00:2500:00:29

sacrum, and then their insertion is through the iliotibial band, and then

00:00:2900:00:36

into the gluteal tuberosity of your femur. So it goes up and down crossing

00:00:3600:00:44

the back of which joint? The hip, and it has a bit of an obliquity to it. So

00:00:4400:00:51

if this is my coccyx and sacrum, and then this is my posterior ilium here right,

00:00:5100:01:04

and then this is my femur, everybody see how that works. So this would be my hip

00:01:0400:01:13

socket, acetabulum, femoral head right, my glutes don't just go like straight up

00:01:1300:01:17

and down this way, they kind of do this

00:01:1800:01:27

right. The big house, you know why the glutes are called the big house? You guys

00:01:2700:01:30

think I'm joking still. You guys, all you guys are all waiting for the punch line

00:01:3000:01:33

of this joke and no it's seriously my favorite muscle. The reason they're

00:01:3300:01:37

called the big house is your glutes are seriously the biggest muscle on your

00:01:3700:01:46

body, that's a fact. And if you ever get a chance to do cadaver work, yeah it's a

00:01:4600:01:50

little gross but definitely a great learning experience, what you'll notice

00:01:5000:01:55

is, is you cut into muscles and they're unbelievably small, the cross-section

00:01:5500:02:02

right, how thick a muscle is, is usually fairly small. You get into like the

00:02:0200:02:08

obliques and the rectus abdominis, and it doesn't matter how fit you are, like this

00:02:0800:02:13

like a few sheets of paper, like the thickness of your workbook. So you're

00:02:1300:02:15

cutting through all these spindley muscles and then you get to the glutes,

00:02:1500:02:22

and it's one of the few muscles on the body that you will go through scalpels,

00:02:2200:02:29

as in several, to try to cut it away so that you can see what's underneath. It is

00:02:2900:02:37

a thick muscle, not just on some people, on all people. So the reason

00:02:3700:02:43

it's called the big house is because it's also the roof right, the most

00:02:4300:02:47

superficial muscle for all of the muscles of the posterior hip. You guys

00:02:4700:02:51

kind of catching my drift. What does this muscle do that would make it so

00:02:5100:03:03

important to be so big, what joint actions? Hip extension, yeah how important

00:03:0300:03:10

is hip extension to your life? Yeah standing up, go ahead get out of that

00:03:1000:03:19

chair without your glutes. Theclunk. Yeah I mean you can get to the floor, you

00:03:1900:03:23

can't get up though. This is hip extension, when I take a step forward

00:03:2300:03:35

what do I have to do? Hip extension. When I run, hip extension right what about

00:03:3500:03:42

when I jump, hip extension. Let's flip this.

00:03:4300:03:52

How do I decelerate? How do I slow myself down, when I walk down a flight of steps?

00:03:5200:04:06

How do I keep myself from going, and just crashing to the ground? It's eccentric

00:04:0600:04:11

right, it's flexion, it's hip flexion, but just like I explained on that

00:04:1100:04:20

exercise graph, is it forceful flexion by your hip flexors? No it's gravity pushing

00:04:2000:04:27

me and my glute slowing me down so they don't crush into it, that makes sense.

00:04:2700:04:34

You guys starting to get it, starting to see why the glutes are so important? So not

00:04:3400:04:40

only is it your primary method of locomotion, propulsion, it's also probably

00:04:4000:04:48

your primary decelerator. Derrick Rose probably could have used stronger what?

00:04:4800:04:53

Glutes. Not saying that was his whole problem, but if he did a little bit more

00:04:5300:05:03

specific glute work he might not have had such a hard time. So I pose the

00:05:0300:05:08

question, who would want a smaller butt?

00:05:0900:05:17

Right no. Have you ever seen an athlete with a small butt? Think about it.

00:05:1700:05:26

No man, you can't be athletic, you can't be high performance without strong hip

00:05:2600:05:33

extension. Anybody who's not functioning well, knee pain, low back pain, a lot of

00:05:3300:05:36

that has to do with not having the strength to hip extend, and having to

00:05:3600:05:44

compensate. Somebody comes in and goes I want a smaller butt, I go there's the door.

00:05:4400:05:49

You come back when you come to your senses and realize that we need to do

00:05:4900:05:54

some glute work if you want to feel good, that makes sense?

00:05:5400:05:58

What else will the glutes do besides hip extension, knowing how important hip

00:05:5800:06:06

extension is? External rotation. Can you guys see how this fiber direction turns

00:06:0600:06:17

the hip out a little bit? If this is my first favorite muscle, that would be my

00:06:1700:06:32

second. So we got the glute max and then we have the glute medius. What joint does

00:06:3200:06:42

my glute medius cross? Your hip, but this one goes from a little lower on the back

00:06:4200:06:50

of the ilium, right into the greater trochanter. So what's its fiber direction?

00:06:5000:06:56

Up and down on kind of the side of my body right. So what does it want to do to

00:06:5600:07:07

my hip? Abduct and a little bit of external rotation. It is a little posterior, you're right.

00:07:1200:07:17

Now I said this is my second favorite muscle, do you think that's because I

00:07:1700:07:21

think abduction is extremely important?

00:07:2200:07:26

Yeah this one's a little tricky right, you guys are going abduction, what

00:07:2600:07:34

functionally do we need abduction for? Like we walk to work like crabs, we don't

00:07:3400:07:41

do that. You do have to make some lateral movements so it is very important to

00:07:4100:07:44

sports, and I said playing defense earlier is like a lot of lateral motion,

00:07:4400:07:52

a lot of abduction, a lot of frontal plane motion. But again I'm kind of

00:07:5200:07:58

flipping this one on you. Not totally talking about the concentric of this

00:07:5800:08:04

muscle. It's a stabilizer which would be its isometric function, so one of the

00:08:0400:08:11

functions of the gluteus medius is when I lift this leg, what does my pelvis want

00:08:1100:08:21

to do? It wants to do this. What joint action is this, what joint action is my

00:08:2100:08:27

in my hip is going from here to here?

00:08:2700:08:33

That's abduction of my hip right. It's just like doing this, only instead of

00:08:3300:08:39

femur on pelvis right, instead of if this is my pelvis instead of femur on pelvis

00:08:3900:08:48

abduction, this is pelvis on femur abduction right. These two things are the

00:08:4800:08:54

same thing going out this way, coming up this way, same thing. So the isometric

00:08:5400:08:59

function of the gluteus medius is when I take a step, it keeps this stable, it

00:08:5900:09:02

keeps this level. Can you imagine how inefficient walking would be if I did

00:09:0200:09:09

this? I don't even know how I would get through that that gait right. Like how

00:09:0900:09:18

would you get your foot to clear. What about, what do my knees want to do every

00:09:1800:09:22

time I take a step? Which direction do they want to go?

00:09:2400:09:30

They want to do this, and if I was really instable and wobbly, what do you think

00:09:3000:09:35

might happen? They collapse inward. Have you guys ever seen somebody do a heavy

00:09:3500:09:41

leg press and like their knees kiss every time they come down? Right, so now

00:09:4100:09:44

you know what that is. You guys can figure you have enough information to

00:09:4400:09:50

figure out why they're doing that. If their knees adduct under that load,

00:09:5000:09:57

who's not strong enough? Their abductors to keep them held in neutral alignment.

00:09:5700:10:07

Does that make sense? Yeah so your gluteus medius it's not as important for

00:10:0700:10:14

its concentric action, what it is is your primary frontal plane stabilization

00:10:1400:10:20

mechanism. Do you guys follow me on that one? It keeps my pelvis from dropping

00:10:2000:10:25

isometrically during gait, it keeps from my knee from caving keeps, my femur in

00:10:2500:10:35

line so that everything can work efficiently. Another muscle that an ACL

00:10:3500:10:43

injury, a lot of that has to do with gluteus medius weakness. So those are my

00:10:4300:10:47

two favorite muscles. Lots and lots of glute work. If you ever come to my

00:10:4700:10:54

workshops just about every dysfunction can benefit from glute work, and I have

00:10:5400:11:00

some torturous ways to work the glutes. I mean if you want your glutes to burn, I

00:11:0000:11:07

can handle that. I have some serious circuits, serious circuits, 10-15 minutes

00:11:0700:11:14

of you just rocking your glutes in all sorts of different ways, from endurance

00:11:1400:11:19

to stability, to reactivity, power.

00:11:3100:11:35

Gluteus minimus, let's start there.

00:11:3900:11:47

Gluteus minimus is a weird muscle, it actually like, if this is the greater

00:11:4700:11:55

trochanter right, and this is the iliac crest, it actually comes over the top

00:11:5500:12:11

this way and to the front of the greater trochanter. If it comes to the front,

00:12:1300:12:22

this is the lateral aspect right, so this is here, but it comes in like this. Yeah

00:12:2200:12:30

your glute min is actually your primary internal rotator of the hip, flexor of

00:12:3000:12:37

the hip. It's on the lateral aspect of the hip so it will also do what?

00:12:3700:12:43

Abduction. Who does that look like? Anybody remember what other muscle does

00:12:4300:12:50

those three joint actions? TFL, nice job.

00:12:5200:12:55

TFLs nasty cousin

00:12:5700:13:06

is the glute min. That makes sense. I know it's really hard to see from that

00:13:0600:13:11

picture. We would have to get a couple cross sections out and show you guys how

00:13:1100:13:18

that gluteus minimus runs over the femoral neck, into the lesser trochanter

00:13:1800:13:24

or the greater trochanter rather, and in front of the gluteus medius, so you could
