2.  Pelvis
 3 fused bones: the ilium, ischium and pubis
 Sacrum
 Articulates with the pelvic bone, and is made up
of fused vertebrae
 Femur
 The longest bone in the body

4.  Iliac crest
 ASIS, AIIS, PSIS,
PIIS
 Iliac fossa

5.  Pubic symphysis
 Superior ramus
 Inferior ramus
5

7.  Ischial tuberosity
 Ischial spine
7

8.  Supports BW
 Serves as the “base”
 Attachment site of many muscles
 Efficient movements (LE)
 Balance & equilibrium

9.  Femur
 Proximal end
 Head
 Neck
 Trochanters
 Acetabulum
 Acetabulofemoral
joint
 Obturator

 Pubis & pubis
2. Sacroilliac joint
 Sacrum & ilium
Lumbosacral joint
 Lumbar & Sacrum
Sacrococcygeal joint

13.  Slightly moveable
 Transmits BW to pelvis
 Subject to loads (GRF)
 Strongest ligaments in
body
 Movement varies due to
sex & individual diff

14.  Males
 Thicker & stronger
ligaments
 No mobility
 Females
 More mobility & laxity
 Monthly hormones
impact laxity

17. • Anterior rotation
• Movement of the upper pelvis in anterior fashion; the iliac
crest tilts forward (anterior tilt). Trunk extension, hip flexion
• Posterior rotation
• Movement of the upper pelvis in posterior fashion; the iliac
crest tilts backward (posterior tilt). Trunk flexion, hip
extension

18. ANTERIOR PELVIC
ROTATION
POSTERIOR PELVIC
ROTATION

19. • Lateral tilt (right and left)
• Example (right): the right ilium moves downward in the frontal
plane in relation to the left ilium. Combination of lateral
flexion of trunk, adduction of left hip and abduction of right
hip
• Right and left transverse rotation
• Example: left: The pelvis rotates left in the transverse plane.
The left iliac crest moves posteriorly in relation to the right
iliac crest

21. LEFT LATERAL PELVIC TILT RIGHT TRANSVERSE PELVIC ROTATION

22. The pelvic girdle is a highly moveable, relatively stable joint
The hip joint, although freely moveable, is not as stable as the pelvic girdle
because it does not contain as many stable, bony joints
• Flexion
• Movement of the femur straight anteriorly in the sagittal plane
• Extension
• Movement of the femur straight posteriorly in the sagittal plane.

23.  Abduction
 Movement of the femur laterally to the side- away
from midline
 Adduction
 Movement of the femur medially- toward the midline
 External rotation
 Rotary movement of the femur around its longitudinal
axis- anterior surface moves away from midline
 Internal rotation
 Rotary movement of the femur around its longitudinal
axis- toward midline

28.  3 df; ball & socket
 Stable & mobile
 Acetabulum
 Cartilage is thicker at edge &
top
 Labrum deepens pocket
 Femoral head
 Cartilage thickest on head
 70% articulates
 Joint capsule
 Strong & dense (ant, sup)

29. 1. Iliofemoral (Y)
• Supports most of BW
• Supports anterior hip (standing)
• Resists external, internal rotation
• Limits hyperextension
 Only anterior pelvic tilt

30. 2. Pubofemoral
• Resists abduction
(primarily)
• Resists external
rotation (some)
3. Ischiofemoral
• Resists adduction
• Limits internal rotation
No ligaments resist flexion (greatest ROM)

31.  When stabilized
 Flexion of hip
 Thigh fixed
 Flexion of trunk
 More active in mid-range
 Leg raise or curl-up
 Increased activity- feet held (curl-up)

32.  Origin
 Transverse process of L1-
5
 Insertion
 Lesser trochanter of femur
 Location

 Movements
 Pelvis: Anterior tilt
 Hip: Flexion

33.  Origin
 Lateral aspect of vertebral
body of T12 and L1
 Insertion
 Iliopecitneal eminence
 Location
 Anterior (more anterior
than psoas
major)/Medial
