Intermediate Pubofemoral Ligament Quiz

Q1. Which proximal attachment is associated with the pubofemoral ligament?

• Anterior inferior iliac spine only
• Pubic acetabular rim and adjacent superior pubic ramus
• Iliac crest
• Ischial tuberosity

Q2. In what general direction do pubofemoral ligament fibers pass from their pubic origin?

• Laterally and inferiorly toward the femoral capsule
• Distally along the tibia
• Posteriorly to the sacrum
• Superiorly into the abdominal wall

Q3. Why does the pubofemoral ligament resist excessive hip abduction?

• Abduction shortens all its fibers
• Abduction actively contracts the ligament
• Abduction tensions its inferomedial capsular fibers
• The ligament crosses the knee joint

Q4. How does the pubofemoral ligament contribute to extension restraint?

• It actively contracts as a hip flexor
• It pulls through the patellar tendon
• Its capsular fibers tighten in extension
• It becomes completely slack in extension

Q5. What is the relationship between the pubofemoral and iliofemoral ligaments?

• They lie in unrelated joints
• They form the knee menisci
• They blend within the anterior capsular complex
• They attach only to the tibia

Q6. Which region of the hip capsule is most closely associated with the pubofemoral ligament?

• Posterior knee capsule
• Posterosuperior capsule only
• Dorsal ankle capsule
• Anteroinferior capsule

Q7. Why are the hip capsular ligaments relatively taut in quiet standing?

• The femoral head leaves the capsule
• The acetabulum becomes shallower
• Standing causes active ligament contraction
• Extension winds the spiral capsular fibers

Q8. How does hip flexion generally affect the pubofemoral ligament?

• It generally decreases tension
• It moves the ligament into the obturator canal
• It always produces maximal tension
• It ruptures the ligament normally

Q9. Which ligament primarily reinforces the posterior hip capsule rather than the anteroinferior capsule?

• Inguinal ligament
• Pubofemoral ligament
• Patellar ligament
• Ischiofemoral ligament

Q10. Why does the pubofemoral ligament not actively generate hip movement?

• It lacks any attachment to bone
• It is a passive collagenous restraint
• It is made of articular cartilage
• It functions as a motor nerve
