Hip Joint and Pelvic Girdle


Hip joint  Acetabular femoral joint
Pelvic girdle  Pelvis


Hip joint and pelvic girdle work together
much like shoulder joint and girdle


Several bones
Pelvis moves in response to trunk and/or thigh
movement
Extremely stable joint



Ligamentous structure
Muscles
Deep acetabulum
Objectives





1. Be able to identify the bones of the hip joint and
pelvic girdle
2. Be able to identify the hip joint, pelvic girdle,
symphisis pubis and sacroiliac joints
3. Be able to identify the landmarks of the femur,
pelvic bones and proximal tibia
4. Be able to identify and describe the movements of
the hip joint and pelvic girdle
5. Be able to identify and describe the general
attachments (distal/proximal), and movements of the
hip joint and pelvic girdle
Hip Joint and Pelvic Girdle Bones


Femur
Pelvic bones: Three sections (fused at maturity)


Ilium
Ischium
Pubis
Extension of spine (5 fused verterbrae)
Coccyx
Pelvic girdle  Pelvic bones, sacrum and coccyx

Hip Joint and Pelvic Girdle

Hip Joint  Joint classification


Multiaxial ball and socket
Pelvic Girdle: Two joints
1. Symphisis pubis:
 Amphiarthrodial (cartilagenous)
2. Sacroiliac joints:
 Diarthrodial nonaxial
Sacroiliac Joints
Symphisis pubis
Acetabular
femoral joint

Hip Joint and Pelvic Girdle
Movements

Hip Joint: Multiaxial ball and socket





Flexion/extension
Abduction/adduction
Circumduction
Internal/external rotation
Pelvic girdle:



Anterior/posterior pelvic rotation/tilt
Right/left lateral pelvic rotation/tilt
Right/left transverse pelvic rotation/tilt
Pelvic Girdle Movements

Anterior pelvic rotation/tilt:


Iliac crest tilts forward
Sagittal plane
Pelvic Girdle Movements

Posterior pelvic rotation/tilt:


Iliac crest tilts backward
Sagittal plane
Pelvic Girdle Movements

Right lateral pelvic
rotation/tilt:



Right pelvis moves
inferiorly in relation to left
pelvis
Lateral plane
Opposite for left side
Right or left?
Pelvic Girdle Movements

Right transverse pelvic
rotation/tilt:



