Hip And Pelvic Girdle Chapter 9

Front 1

The Hip
Acetabular Joint

Back 1

relatively stable due to it's bony architecture, strong ligaments, and large supportive muscles. Functions in weight bearing and locomotion.

Front 2

Bones of hip

Back 2

ball and socket joint
head of femur connects with acetabulum of pelvic girdle.
Femur projects out laterally towards greater trochanter.

Front 3

Bones of Pelvic Girdle

Back 3

right/left pelvic bone joined together posteriorly by the Sacrum.
Pelvic bones made up of three bones: ilium, ischium, and pubis.
At birth they are each separated, at maturity they are fused into one bone

Front 4

Pelvic Bone 3 areas

Back 4

ilium - upper two - fifths
ischium - lower two - fifths, posterior.
pubis - anterior and lower one - fifth

Front 5

Joints - Pelvic Bone- Anterior Area

Back 5

Symphysis Pubis -
an amphiarthrodial joint

Front 6

Pelvic Bone - Posterior Area

Back 6

Sacrum located between two pelvic bones-
sacroiliac joint

Front 7

Strong Ligaments

Back 7

form rigid slightly movable joints
bones are large and heavy for the most part.
very minimal oscillating movements

Front 8

Hip Joint - enarthrodial joint
femur inserts into acetabulum of pelvis

Back 8

one of the most mobile joints
multiaxial arrangement is the reason
great deal of stability - bony architecture
relatively few dislocations and subluxations

Front 9

Ligaments of Hip

Back 9

strong and dense ligaments
reinforces the joint

Front 10

Anterior Hip ligaments

Back 10

iliofemoral or Y ligament
