Q1. Which two muscles combine to form the iliopsoas tendon near the lesser trochanter?
- Gluteus medius and minimus
- Adductor longus and gracilis
- Semitendinosus and semimembranosus
- Psoas major and iliacus
Q2. Where is the lesser trochanter best seen on the femur?
- Only from inside the acetabulum
- From the posterior aspect
- Only from the distal articular surface
- From the anterior knee
Q3. Which ridge descends inferiorly from the lesser trochanter toward the linea aspera?
- Soleal line
- Pectineal line
- Intercondylar line
- Gluteal tuberosity
Q4. Which muscle attaches to the pectineal line just inferior to the lesser trochanter?
- Pectineus
- Rectus femoris
- Fibularis longus
- Popliteus
Q5. What is the relationship of the lesser trochanter to the intertrochanteric crest?
- It lies on the distal end of the femur
- It is completely separate from the crest
- It forms the lateral end of the patellar surface
- It lies at the inferomedial end of the crest
Q6. Why does the lesser trochanter provide effective leverage for iliopsoas?
- It prevents any movement of the femur
- It places iliopsoas inside the knee capsule
- Its projection helps iliopsoas generate a hip flexion moment
- It converts iliopsoas into a knee extensor
Q7. Which action can iliopsoas also contribute to in addition to hip flexion?
- External rotation of the hip
- Toe abduction
- Knee flexion only
- Ankle inversion
Q8. What type of ossification center is associated with the lesser trochanter during development?
- No ossification center
- A carpal ossification center
- A secondary ossification center
- The primary shaft ossification center
Q9. Why is the lesser trochanter useful on radiographs of the proximal femur?
- It determines ankle alignment
- It identifies the patellar surface
- It directly measures tibial length
- Its apparent prominence helps assess femoral rotation
Q10. What happens to the apparent prominence of the lesser trochanter on an anteroposterior radiograph when the femur is externally rotated?
- It moves into the knee joint
- It becomes more prominent
- It disappears completely
- It becomes the greater trochanter
