1 Hip Joint and Pelvic Girdle
Anatomy and Physiology of Human Movement 420:050

2 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

3 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

4 Hip Joint and Pelvic Girdle Bones
Femur Pelvic bones: Three sections (fused at maturity) Ilium Ischium Pubis Sacrum Extension of spine (5 fused verterbrae) Coccyx Pelvic girdle  Pelvic bones, sacrum and coccyx

5 Pelvic bones Femur Sacrum Coccyx

6 Ilium Upper 2/5 Ischium Posterior/lower 2/5 Pubis Anterior/lower 1/5

7 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 proximal femur and pelvic bones 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

8 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

9 Sacroiliac Joints Symphisis pubis Acetabular femoral joint

10 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 proximal femur and pelvic bones 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

11 Femoral and Pelvic Landmarks

12 Head Neck Greater trochanter Lesser trochanter Gluteal tuberosity

13 Lateral epicondyle Medial epicondyle Patella

14 Anterior superior iliac spine Iliac crest Ilium
Anterior inferior iliac spine Pubis Acetabulum Ischium Obturator foramen Ischial tuberosity Anterior

15 Lateral tibial condyle
Medial tibial condyle Lateral tibial condyle Fibular head Tibial tuberosity

16 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 proximal femur and pelvic bones 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

17 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

18 Pelvic Girdle Movements
Anterior pelvic rotation/tilt: Iliac crest tilts forward Sagittal plane

19 Pelvic Girdle Movements
Posterior pelvic rotation/tilt: Iliac crest tilts backward Sagittal plane

20 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?

21 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?

22 Movement Summary: Hip Joint: Pelvic Girdle: Multiaxial ball and socket
F/E, Abd/Add, I/E rotation, Circ. Pelvic Girdle: Rotation in all three planes
