🦴 Introduction to the Hip Bone Anatomy
The video starts with an introduction to the hip bone, also known as the innominate bone, which forms part of the pelvic girdle. It describes the structure and function of the hip bone, noting that it is made up of three parts: the ilium, pubis, and ischium. These three bones fuse at the acetabulum, a cup-shaped structure, and form a part of the pelvic girdle. The video explains the articulation points, such as the pubic symphysis and sacroiliac joints, and introduces the side determination of the hip bone.
💪 Detailed Anatomy of the Iliac Crest
The focus shifts to the iliac crest, which has a superior and inferior end. The superior end is known as the iliac crest and is divided into a ventral and dorsal segment. The ventral segment is further subdivided into three parts: the outer lip, inner lip, and intermediate area. Each part serves as an attachment site for various muscles, such as the tensor fasciae latae, external oblique, and latissimus dorsi. The segment also provides details on the attachments for the inner lip and intermediate area, including muscles like the transversus abdominis and quadratus lumborum.
🔍 Exploring the Gluteal and Sacropelvic Surfaces
The video discusses the gluteal surface, which is divided into four areas by three gluteal lines: posterior, anterior, and inferior. Each area serves as an attachment for specific muscles like the gluteus maximus, gluteus medius, and gluteus minimus. The discussion moves on to the inner iliac surface, which is concave and bounded by several borders. The sacropelvic surface, located behind the medial border, is divided into three parts: the iliac tuberosity, the auricular surface, and the pelvic surface. Each part has unique features and attachments, including ligaments and muscle fibers.
👍 Final Thoughts and Video Conclusion
The video wraps up with an overview of the anatomy discussed, particularly the importance of the sacroiliac joint and its ligaments. The segment highlights attachments for structures like the sacrospinous ligament and the origin points for muscles like the piriformis and obturator internus.

hello friends welcome to the viva house
of anatomy today we will discuss about
the hip bone
the another name of the hip bone is a
innominate bone it is an irregular type
of the bond and it will form the pelvic
girder
this is the pelvic cutter the right and
the left hip bone together with the sac
ground will form the pelvic girder or a
morning pelvis
now
it is homologous with the scapula of a
upper lip
the each hip bone is made up of three
parts or a three bone that is
the
ilium
pubis
and tissue
the ilium part will form the upper part
of the bone
the pubis is a thin bond which lies
enduro inferiorly in the hip bone and
the ischium is a thicker than the pubis
it will form the posterior inferior part
of the hip bone
now this three bone helium pubis and the
issue they will
fuse at a cup shaped hollow structure
which is known as a acetabulum
below the acetabulum you can see one
large foramina this foramina is known as
a obturator for amino which will
separate the thin previous
anteriorly from the thick ischium
posterior
now overall
the hip bone is having two component
dorsal component and ventral component
you can see the dorsal component is
formed by the helium bond and the
ventral component is formed by the pubis
and the issue
now we will see
the articulation of the hip bone
now
here
the hip bone
with the hip bone and evenly they will
fuse and form the pubic symphysis joint
which is a secondary
cartilaginous joint
the posteriorly
the hip bone on the either side
it will articulate with the lateral end
of the sacrum to form the
sacroiliac joint which is a para joint
it is a plane variety of cytokine joint
and the third this acetabulum which is
articular it will articulate with the
head of the femur to form the hip joint
which is a ball and socket type of a
synovial joint
now we will first we will discuss the
side determination of the hip bone
the first
the ilium flat expanded ilium will form
the upper part of the bone it lies
superiorly
the second
the scw
the articular part acetabulum is facing
literally
third
objective for amino lies below the scwm
it is separated by
so
the bond in my hand is off the right
side
now we will discuss the three parts of
the hip bone
today only we will discuss in this video
the ilium part now the ilium is a flat
expanded part lies in the upper part of
the hip bone it is having
two ends
three borders and three surface first we
will discuss the two ends the two ends
are the superior and
and
inferior
the superior add is in form of the thick
reach which is known as the iliac twist
and the inferior and it will fuse with
the pubis and the ischium at an
acetabulum and it will form the upper
two-fifth of a acetone now we will see
in detail about the superior end which
is also known as the india quest
now the iliac crest is extended from the
anterior superior iliac spine anteriorly
to
the posterior superior iliac spine
posterior
now the electricity is divided into
the ventral segment larger one and the
dorsal segment
the ventral segment formed the more than
the anterior two third of the index fist
up to this line this is the ventral
cycle
and the dorsal segment
will form the less than posterior one
third of the interaction
the ventral segment is divided into
three parts
the outer lip
inner lip
and intermediate area
on its outer lip
four centimeter behind the anterior
superior iliac spine it will present one
elevated area which is known as a
tuberosity of electricity
now we see the attachment of these three
parts first the outer nip
the outer lip in its mold extent gives
the attachment to the face
first
the second in front of this tuberosity
the outer lip this area will give origin
to the tensor facial line
second third the tuberosity itself
provides attachment to the iliotibial
tract
the fourth
the outer lip in its anterior two-third
part provides insertion of external
oblique muscle of a abdomen and the last
fit
the outer lip in its posterior one third
part gives the origin of a latissimus
dorsi muscle
now the attachment of a inner lip
inner lip in its anterior two-third part
will give origin to the transversus
abdominis muscle of the abdomen
and leave to this muscle provides
attachment of fascia a transversal and
fascia helium
now the inner lip in its posterior one
third provides origin of a quadratus
lumborum muscle now the
third part intermediate area
intermediate area in its anterior
two-third part give origin to the
internal oblique muscle of abdomen
this is all about the ventral segment of
a liquid now focus on the dorsal cycle
the torso segment will form the less
than posterior one third of an india
crease
it is having
the literal slope
median slope and intermediate reach
the lateral slope will give origin to
the upper fiber of a gluteus maximus
muscle
and medial slope will give orange into
the erector spine muscle
now
the two end of the iliac wrist
anteriorly and usually left spine
posteriorly posterior superior spine
anterior superior spine you can felt in
front of a flank clearly in the living
the posterior superlax white the
importance of it is that it lies at the
level of a h2 vertebra and at this level
the subarachnoid space
will end so this is all about the upper
end of a
helium that is the indian crystal
now the second part the border it is
having three water and clear water
posterior water and medium one for the
anterior border antibodies extend from
the anterior superior iliac spine above
up to the acetabulum below it will so in
the upper and anterior superior spine
followed by one note
below the notes anterior inferior
relaxed point and there is a rough
triangular area below the anterior
infield x point now the attachment
anti-super ellipse point will give
origin to the sartorius muscle
and
the lateral end of the equinal ligament
the second the nose below the anterior
spirits point will launch is the literal
cuteness now of a thigh
now sometimes this now in this nose will
trap
below the inguinal ligament and it will
cause the pain along the lateral side of
pain and tingling sensation on the
lateral side of the thigh which is known
as a merely parasitica
the second
the anterior inferior spine give
attachment to the ilio femoral ligament
and the straight head of a rectus
femoris muscle
now the second border that is the
posterior border
the posterior border will extend from
the posterior suprahelic spine ago up to
the posterior water of ischium below
now it will show
in the upper part posterior superior
left point few centimeter below there is
a posterior inferior lex point
followed by the deep nose which is known
as a greater cr notion
now its attachment
the posterior ball border will provides
attachment to the sacrotuberous ligament
up to the upper part of the posterior
inferior index point
the upper margin of a greater psiotic
nose will give origin to the few fiber
of the pyriformis
now this greater crdic nodes
it will convert it into the foramina by
the sacrotuberous ligament posteriorly
and the sacrospinous ligament
below
greater sciatic foramen third border is
a medial border which lies on the inner
side of a hip bone it will extend from
the iliac crystal above up to
iliopubic aminos below now this medial
border is divided into three parts npa
one third
middle one third and
posterior the anterior one third will
form the arcuate line
the middle one third will form the
anterior curved line of a follicular
surface
and the posterior one third is rough the
third part in the helium is a surface it
is having three surface the gluteal
surface that is outer one
the iliac surface inner one and the
sacral pelvic surface this is also lies
on the inner side
first we will discuss the gluteal
surface
the gluteal surface is convex in its
anterior part and concave behind like a
helium twist
now this gluteal surface is divided into
four area
by three lengths
these lines are the first one is a
posterior gluteal line
the posterior gluteal line will extend
from the inner crease
four to five centimeter in front of a
posterior superior iliac spine
it will runs downwards and it will end
just above the greater crt nodes the
forces
the second anterior gluteal line and the
excluding line start four centimeter
behind the anterior superior iliac spine
it will pass this first backwards
and then downwards to end at the middle
of
upper border of greater cia technology
this one is an anterior nuclear line the
third one is a inferior gluteal line it
is ill-defined
it will start
above and behind the anterior inferior
iliac spine
it will go backward and slightly
downwards
to end
at the apex of a greater sciatic note
inferior gluteal line
so this three line
will divide the gluteal surface into
four area
now the attachment on the gluteal
surface
the behind the posterior gluteal line
this area will give origin to the
nucleus maximus muscle
the second area between the anterior
gluteal line and posterior gluteal line
will be orange into the gluteus medius
muscle
the third area between the inferior
gluteal line and anterior gluteal line
will give origin to the gluteus minimus
muscle
and the fourth area below the inferior
gluteal line this area will give origin
to the reflected aid of a rectus femoris
muscle
now
the second surface that is lies on the
inner side
that is
called a iliac surface or inject force
which is a concube
now this inlet fossa or iliac surface is
bounded entitilely by the anterior
border
posteriorly by the posterior border
sorry medial border
superiorly by the ventral segment of the
iliacrist and below by the iliopubic
amides this indian force are
from its upper two third part give
origin to the iliacus muscle
the last surface is a sacropelvic
surface which also lies on the inner
surface
it lies
behind the medial border
behind the medial border
and it is divided into three parts
the first part
the most upper part is a
iliac tuberosity
anterior inferior to electric velocity
there is a particular area which is
articular and entero inferior to the
auricular area there is a patrick
surface
the first we will see the
tuberosity iliac tuberosity is a large
rough upper part of the sacropelvic
surface
it is elevated in the middle and the
depressed
elsewhere
now this
[Music]
electricity in the most of the part
will provides attachment of intrusions
sacroiliac ligament
in its posterior part it will gives
attachment to the dorsal sacroiliac
ligament
and superiorly it will provides
adjustment to the ilio number ligament
now the second part of a sacropelvic
surface that is a particular surface
which is
articular but repeated
it will articulate with a sacrum to form
the sacroiliac joint which is a plane
variety of sinus culture
its anterior convex margin will provide
attachment to
the ventral sacral india ligament
now the third part of the sacropalic
surface the pelvic surface
it lies antero inferior to the auricular
surface
along with the upper margin of the
greater sciatic notes it will form the
pre auricular
surface which is deeper in the female
than in the mid
this pelvic surface
in its upper part along the margin of
greater periodic noise will give origin
to the few fiber of piriformis and the
remaining part smooth part will give
origin to the obturator internal muscle
