Hip Joint Quiz

Which muscle can be the antagonist for both hip extension and knee flexion

Rectus Femoris (biarticular muscle)

During pure hip flexion about the neutral axis, the head of the femur does what in the acetabulum arthrokinematically

Spins only

Which angle represents the size of the superior load bear surface of the acetabulum?

Large Wiberg Angle

A steep or larger inclination angle is associate with what?

Higher joint contact forces at the hip

The Anteversion angle discussed is characterized by what?

The morphological torsion of the femur from its proximal to distal end

The acetabulum faces which three directions?

anteriorly, laterally, and inferiorly

The ischiofemoral ligament is tensioned mainly by what hip position

Hip extension

What ligament is the joint space of the hip joint and acts as a secondary stabilizer and a conduit for blood supply and innervation of the hip joint?

Someone walking with a toe out gait is likely to have what?

Small Anterversion angle

An inclination angle greater than 125 degrees is characteristic of a hip that displays?

Coxa Valga

Excess anterior pelvic tilt during a squat will also cause movement of what?

Lumbar extension

During the open chain leg movement of right hip abduction will also cause what?

No compensatory movement

Which muscle does not participate in hip abduction?

Biceps femoris

The limitation in the hips flexion range of motion when the knee is fully extended is due in part to which of the following?

Passive insufficiency of semimembranosus

Which muscles originate on the anterior superior iliac spine of the ilium?

What muscle is outlined in yellow in this image?

Gluteus Medius

What is the primary action of the gluteus medius

Hip abduction

What is this ligament highlighted in yellow

Ischiofemoral ligament

• Psoas and Iliacus

Should the deadlift begin with the hip higher than the knees

yes

Tightness in what muscle would most likely contribute to valgus knee collapse during a squat
