LL - Hip Flashcards
What does the angle of Wiberg represent?
Inferior tilt of acetabulum
Which extra capsular ligament is the strongest (consists of two bands) and where is it situated?
Iliofemoral ligament
Origin: AIIS, acetabular limbus
Insertion: Intertrochanteric line
Which direction is the glide in open chain abduction?
Inferior
Around which plane and axis do anterior and posterior pelvic tilting occur?
Sagittal plane
Coronal axis
What limits the range of hip adduction?
Limited by the opposite limb, tension in the abductors and iliofemoral ligament
Which are the agonists for hip flexion?
iliopsoas, sartorius, tensor fasciae latae, rectus femoris, adductor longus, pectineus
Name this ligament and its origin and insertions:
Ischiofemoral
Origin: Ischium
Insertion: Greater trochanter
What can be an indication of femoral retroversion (looking at position of foot)?
External rotation at foot
What is coxa valga?
pathologic increase in the angle of inclination of the femur
What is the name of this angle in the hip?
Angle of inclination (neck-to-shaft angle)
What is the angle of torsion in the hip?
Degree of torsion of neck of femur from femoral condyles, normal is anterior
What happens to the extra-capsular ligaments in hip flexion?
All 3 ligaments are relaxed
What are the synergists to hip flexion?
adductor brevis, gracilis and minimally: gluteus minimus (anterior fibers)
Around what plane and axis does pelvic rotation occur?
Vertical/longitudinal axis, transverse/horizontal plane
What are the antagonists of hip internal rotation?
obturator internus, quadratus femoris, gemellus superior + inferior and gluteus maximus (inferior fibers)
