Intermediate Femoral Neck Quiz

Q1. What is the approximate normal adult femoral neck-shaft angle?

• About 90 degrees
• About 125 degrees
• About 45 degrees
• About 180 degrees

Q2. What is coxa vara?

• A decreased femoral neck-shaft angle
• An increased femoral neck-shaft angle
• A fracture of the tibial plateau
• A widened ankle mortise

Q3. What is coxa valga?

• A decreased femoral neck-shaft angle
• An increased femoral neck-shaft angle
• A fracture of the patella
• A posterior hip dislocation

Q4. What does femoral anteversion describe?

• Posterior rotation of the tibial plateau
• Inferior displacement of the femoral head
• Anterior rotational orientation of the neck relative to the distal femur
• Medial displacement of the patella

Q5. Where does the hip capsule attach anteriorly on the proximal femur?

• At the lateral femoral condyle
• Along the linea aspera only
• Along the intertrochanteric line
• At the tibial tuberosity

Q6. How does the posterior capsular attachment differ from the anterior attachment around the femoral neck?

• It attaches to the posterior neck medial to the intertrochanteric crest
• It attaches along the patellar surface
• It completely excludes the femoral neck from the capsule
• It attaches to the fibular head

Q7. Where do retinacular vessels travel in relation to the femoral neck?

• Across the tibial plateau
• Inside the patellar ligament
• Only within the femoral shaft medullary cavity
• Along the neck within synovial retinacula

Q8. Why does the femoral neck increase the range of hip movement?

• It fuses the head directly to the acetabulum
• It prevents rotation of the femur
• It converts the hip into a hinge joint
• It offsets the head from the shaft and provides movement clearance

Q9. What type of force is substantially transmitted through the femoral neck during weight bearing?

• Only torsion with no compression
• Only tension with no compression
• Combined compressive and tensile stresses
• No mechanical stress

Q10. Which region of the femoral neck is especially important for vessels supplying the superior femoral head?

• Medial femoral condyle
• Patellar surface
• Distal anterior femoral shaft
• Posterosuperior neck
