Hip Joint and Pelvic Girdle

Anatomy and Physiology of Human Movement420:050

Hip Joint and Pelvic Girdle Hip joint Acetabular femoral joint Pelvic girdle Pelvis

Several bones Hip joint and pelvic girdle work together much

like shoulder joint and girdle 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 Hip Joint Joint classification

Multiaxial ball and socket Pelvic Girdle: Two joints

1. Symphisis pubis: Amphiarthrodial (cartilagenous)

2. Sacroiliac joints: Diarthrodial nonaxial

Acetabular femoral joint

Symphisis pubis

Sacroiliac Joints

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: Right iliac crest moves

posteriorly in relation to the left iliac crest

Transverse plane Opposite for left side

Right or left?

Movement Summary: Hip Joint:

Multiaxial ball and socket F/E, Abd/Add, I/E rotation, Circ.

Pelvic Girdle: Rotation in all three planes
