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.

Ilium

Ilium means flank

The largest area of the hip

bones

Forms the superior region of

the coxal Consists of 2 large plates that

Ant. Sup. Iliac spine - related

with Inguinal Lig., Sartorius,

Fascia lata & Tensor Fascia

lata

Ant. Inf. Iliac spine - related

with Rectus Femoris &

Iliofeoral lig. Notch between two spines

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

8/2/2019 Coxae Bones

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
