Intermediate Iliofemoral Ligament Quiz

Q1. Which two major bands are commonly described within the iliofemoral ligament?

• Superficial and deep deltoid bands
• Medial and lateral meniscal bands
• Superior and inferior bands
• Anterior and posterior cruciate bands

Q2. What forms the proximal base of the iliofemoral ligament?

• Iliac crest and inguinal ligament
• Ischial tuberosity and sacrotuberous ligament
• Pubic symphysis and obturator membrane
• Anterior inferior iliac spine and adjacent acetabular rim

Q3. Why does the iliofemoral ligament tighten during hip extension?

• Anterior capsular fibers become tensioned as the hip extends
• The ligament passes behind the knee
• Extension detaches it from the femur
• Its fibers shorten actively like muscle

Q4. Which additional hip motion is restrained by portions of the iliofemoral ligament?

• Ankle eversion
• Toe flexion
• Knee extension
• External rotation

Q5. How does the iliofemoral ligament relate to the fibrous capsule of the hip?

• It replaces the acetabular labrum
• It is an intracapsular tendon
• It is a reinforced thickening of the anterior fibrous capsule
• It lies entirely outside the capsule without blending

Q6. Which femoral landmark receives the distal fibers of both major bands?

• Intertrochanteric line
• Medial femoral condyle
• Greater trochanteric crest only
• Lesser trochanter only

Q7. Why can the iliofemoral ligament reduce muscular energy expenditure during quiet standing?

• It produces ankle plantarflexion
• It actively contracts during standing
• It provides passive restraint against excessive extension
• It directly locks the knee menisci

Q8. How does hip flexion generally affect tension in the iliofemoral ligament compared with extension?

• It generally reduces ligament tension
• It tears the ligament physiologically
• It converts the ligament into a tendon
• It always produces maximal tension

Q9. Which neighboring anterior hip ligament arises more medially from the pubic region?

• Ligament of the head of the femur
• Pubofemoral ligament
• Sacrotuberous ligament
• Ischiofemoral ligament

Q10. What is the functional consequence of the spiral orientation of capsular fibers around the hip?

• They tighten in extension and contribute to joint stability
• They eliminate the need for articular cartilage
• They produce active femoral rotation
• They prevent all hip flexion
