What does the pelvic girdle consist of?
- Right & Left pelvic bones joined by the axial skeleton via the sacrum and the 5th lumbar vertebra posteriorly
- Right and Left hemi-pelvis meets at pubic symphysis anteriorly

What are the hip joint movements? (pelvic motion on femur)

- Lateral Tilt- frontal plane
- Protraction/Retraction- transverse plane
Adductor Longus
A: Hip Adduction
O: Pubis
I: Middle one third of the linea aspera
N: Obturator
What allows stability for the hip joint?
high congruency and firm connective tissue between the femoral head and acetabulum equal joint stability
Peroneus Tertius
A: assists somewhat in ankle eversion and dorsiflexion
O: distal medial fibula
I: base of fifth metatarsal
N: deep peroneal nerve
Give an example of a pelvic motion on the femur.
leaning over to pick up an object from the floor
What is the lesser trochanter?
located medially and inferiorly to the greater trochanter
What does the acetabulofemoral joint do?
- Transmits large forces between trunk and ground
- Elevates and lowers body
- Works with body’s locomotion system
What does the ilium allow?
The ilium’s large surface area provides numerous attachment sites for many muscles
Name the Deep Group of the LE
Long Toe Flexors
Flexor Hallucis Longus
Flexor Digotorum Longus
Tibialis posterior
What is the symphysis pubis?
amphiathrodial connection between two pubic bones
What does the femur articulate with?
articulates with the hip proximally, and distally at the knee with the tibia
How much does the ischium contribute to the acetabulum?
40%
What are the primary functions of the pelvis?
1- Provides stable base for HAT (head, arm, and trunk)
2- contains visceral organs
3- transmits and absorbs forces to and from HAT superiorly and LE inferiorly
Gastronemius
A: Ankle plantar flexion & Knee flexion
O: Medial and Lateral Femur Condyles
I: Posterior Calcaneus
N: Tibial Nerve
What bones are below the knee?
Tibia & Fibula (leg)
Tarsals
Metatarsals
Phalanges
What is the obturator foramen?
vessels and nerves travel through the obturator foramen to the lower extremities
How much weight does the fibula carry?
carries 10% of weight
Name the hip lateral rotators and
A
O
I
Obturator externus, internus
Gemellus Superior, inferior
Quadratus femoris
Piriformis
A: Hip Lateral Rotation
O: Posterior ischium, sacrum, pubis
I: greater trochanter of the femur
N: Obturator and L4, L5, S1, S2
Tibialis Posterior
A: ankle inversion; assists in plantar flexion
O: interosseous membrane, adjacent tibia and fibula
I: navicular and most tarsals and metatarsals
N: Tibial Nerve
What type of production is the pelvis involved in?
Power production (closed chain function) rather than mobility
Pectineus
A: Hip flexion and adduction, medial rotation
O: Superior Ramus of the Pubis
I: Pectineal line of the femur
N: Femoral Nerve
What is the linea aspera?
the origin for adductor muscles

90% of body weight
Tibialis Anterior
A: Dorsiflexion, ankle inversion
O: Lateral tibia & interosseous membrane
I: first cuneiform and metatarsal
N: deep peroneal nerve
How many bones are in the foot and ankle?
They’re are 26 bones of the foot and ankle
What are the hamstrings?
Biceps femoris, semitendinosus, semimembranous are known as the hamstrings
