Antomical Location & Position
Location: It is situated on the both sides of the sacrum
and connected to the femur bone.
Position: hold the bone in such a way
a) The long and curved border should be up wards & narrowpart downwards.
b) The cup shaped depression should be outwards with its
notch directed downwards.
c) The symphyseal surface will lie in the median plane.d) Ant. Sup. Iliac spine and Pubic tubercle lie in the same
vertical plane.
e) Acetabulum will direct to the side it belongs.

PARTS OF HIP BONE
It has three parts:
a)Ilium corresponds to
scapula
a)Pubis corresponds to
part of calvicle
a)Ischium corresponds to
corocoid process

Ilium
Ilium means flank
The largest area of the hip
bones
Forms the superior region of
the coxal Consists of 2 large plates that
help to support the internal
organs and provide
attachment for muscles of the
back, sides, and the buttocks The hip joint of the femur is
part of the ilium

Anterior Border 1. Anterior Border it has
Ant. Sup. Iliac spine - related
with Inguinal Lig., Sartorius,
Fascia lata & Tensor Fascia
lata
Ant. Inf. Iliac spine - related
with Rectus Femoris &

Posterior Border
Long curved border. Extends frompost. Sup. Iliac spine above to upper
end of post. Border of Ischium below
& is continuous with it.
Post. Sup. Iliac spine & Post. Inf. Iliac
spine : Between them Sacro tuberus
Ligament is attached

Ischium
It attaches to the gluteal loin
This is the bone we sit on
It consists of 2 broad curves
Lies below the ilium
It is attached to the pubis inthe front and the ilium in the
back
It functions as a place for
muscle attachment which
provides support andprotection

Pubis Bone
It is the located at the ventraland anterior side (front-mostportion of the coxae bone.
It attaches to the ilium and onthe sides of the ischium on the
bottom It provides structural support
as well as allowing for musclesto attach to the inner thigh
It is covered by a layer of fat
(that is covered by monspubis) which protects the pubicbone
The left and right hip bonesjoin at the Pubic symphasis

Acetabulum
Part of the ball and socket joint
The hip joint is a joint betweenthe acetabulum and the femar
Its very deep which allows formore stability, but less
flexibility Its function is to support the
weight of the body
This area would similar to acondyle because it is rounded,
smoother, and more articular The smoothness allows there
to be less friction and irritationwith movement
