How many degrees of motion does the hip have?
3
What is the closed packed position for the hip?
Extension, abduction and IR
Describe the arthokinematics for open kinetic chain hip flexion.
The femur rolls anteriorly and glides posteriorly
Describe the arthrokinematics for closed kinetic chain abduction.
The pelvis rolls and glides superiorly.
True or False: the Pubofemoral ligament is taut with extension and ER.
False, it is taut with abduction and extension
True or False: the angle of inclination is in the frontal plane.
True
What is the normal angle of inclincation?
125 degrees
What postural compensation is associated with coxa vara?
Hip adduction
True or False: the angle of torsion occurs in the transverse plane.
True
What is the normal angle of torsion?
15 degrees of anteversion
What postural compensation is associated with excessive anterversion?
Toeing in
True or False: An anterior pelvic tilt is hip flexion in a closed kinetic chain.
True
What muscles cause a posterior pelvic tilt?
Rectus Abdominis, Gluteus Maximus, and the hamstrings
What muscles cause a anterior pelvic tilt?
Erector spinae, rectus femoris and Iliopsoas
True or False: a posterior pelvic tilt causes a "flat" back posture.
True
What nerve roots innervate the Adductor Brevis?
L2-3
What nerve roots innervate the Piriformis?
L5 S1-2
What nerve roots innervate the Gemellus superior?
L5-S1
What nerve roots innervate the Gluteus Maximus?
L5-S1-2
What nerve roots innervate the Sartorius?
L2-3
Describe the arthokinematics for open kinetic chain hip abduction.
The femur rolls laterally and glides medially
None
Describe the arthokinematics for open kinetic chain hip IR.
The femur rolls anteriorly and glides posteriorly
What are the advantages associated with Coxa Vara?
The moment arm for the hip abductors is increased, improved joint stability
What are the advantages associated with Coxa Valga?
Less shear forces across the femoral neck, the length of the abductors is increased
What are the disadvantages of Coxa Vara?
Increased shear forces across the femoral neck, the length of the abductors is decreased
What are the disadvantages of Coxa Valga?
The moment arm for the hip abductors is decreased, diminished joint stability
What abnormal alignments accompany coxa vara?
Valgus at the knee, internal rotation of the tibia and excessive pronation at the subtalar joint.
Page 471
What is the loosed packed position for the hip?
30 degrees of flexion, 30 degrees of abduction, and slight ER
How would you treat a patient that presents with a posterior pelvic tilt?
Stretch the Abdominals, Gluteus Maximus, and Hamstrings and strengthen the iliopsoas, rectus femoris and back extensors
Page 419 &412
Name the hip internal rotators.
Gluteus medius and minimus, TFL, Adductor longus and brevis, pectineus, Semitendinosus and semimembranosus
Page 410
What is the capsular pattern of the hip?
Flexion >abd>IR
What are the 3 regions of the pelvis?
Ilium, ischium and pubis
Name the muscles that insert into the greater trochanter.
Glut medius, Glut min, Piriformis, Obturator In, Obturator Ex, Gemellius Sup, Gemellius Inf
Name the muscle that inserts into the lesser trochanter.
Iliopsoas
