Intermediate Pubofemoral Ligament Quiz

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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