1. The Anatomy of the Hip and Pelvis

2. Bony Landmarks of Femur
Bony Anatomy
Femur = Thigh Bone
Longest and strongest bone
Designed for maximum support and mobility during weight- bearing activity
Bony Landmarks of Femur
Head of Femur
Neck of Femur
Greater Trochanter
Lesser Trochanter

3. Bony Anatomy Pelvis Bony ring formed by two coxal bones
3 Sections: Ilium, Ischium, and Pubis
Sacrum
Coccyx

4. Bony Anatomy

5. Bony Anatomy Iliac Crest Anterior Superior Iliac Spine (ASIS)
Bony Landmarks of Pelvis
 Iliac Crest
 Anterior Superior Iliac Spine (ASIS)
Ischial Tuberosity
 Acetabulum
 Anterior Inferior Iliac Spine (AIIS)

6. Hip Joint Hip joint  Femoral Acetabular Joint Ball and socket joint
Head of femur = ball
Acetabulum of pelvis = socket
Extremely stable joint
Great bony stability -- deep acetabulum!
Strong ligaments
Strong muscles

7. Pelvic Girdle
Pelvic girdle = Pelvis (2 coxal bones), sacrum, and coccyx
Two joints
1. Sacroiliac joints
Between sacrum and pelvis (ilium)
Common place for low back pain
2. Pubic Symphysis
Fibro-Cartilage
Allows some movement to occur

8. Hip joint and pelvic girdle work together
Pelvis supports spine and trunk and transfers weight to legs

9. Stabilizing Structures

10. (Moving thigh forwards)
Hip Range of Motion
Hip Flexion
(Moving thigh forwards)

11. Hip Extension (Moving thigh backwards)
Hip Range of Motion
Hip Extension (Moving thigh backwards)

12. Hip Range of Motion
Hip Adduction
(Moving the thigh closer to midline)

13. Hip Range of Motion Hip Abduction
(Moving the thigh away from the midline)

14. Hip Internal Rotation (Head of femur rolls forward- close the gate)
Hip Range of Motion
Hip Internal Rotation (Head of femur rolls forward- close the gate)

15. Hip External Rotation (Head of femur rolls backward- open the gate)
Hip Range of Motion
Hip External Rotation (Head of femur rolls backward- open the gate)

21. Hip Muscles: Hip External Rotator
Location: Deep posterior hip (underneath gluteals)
Piriformis
