Intro

Question 0

Angle of declination (torsion angle)

Answer 0

• between head and neck of femur and transverse axis of femoral condyles along shaft
• allows for flexion/extension, adduction/abduction, rotation of thigh

Question 1

Angle of inclination

Answer 1

• long axis of head and neck of femur project superomedially
• proximal femur is “L-shaped”
• average in adults = 126 degrees (115-140)
• less in females
• allows greater mobility of femur at hip joint - places head and neck of femur more perpendicular to acetabulum

Question 2

Patella

Answer 2

• sesamoid bone

- increases biomechanical advantage of quads

Question 3

Lateral malleolus

Answer 3

• on fibula
• more prominent than medial malleolus
• helps hold talus in socket

Question 4

Gluteal region

Answer 4

• bounded superiorly by iliac crest, greater trochanter, and ASIS
• bounded inferiorly by gluteal fold

Question 5

Superficial gluteal muscles

Answer 5

• gluteus max, med, min

- tensor fasciae latae

Question 6

Deep gluteal muscles

Answer 6

Piriformis, obtruator Internus, superior and inferior gemelli, quadratus Femoris
- lateral rotators

Question 7

Gluteus bursae

Answer 7

• reduce friction and permit free movement
• separates glut max from adjacent structures
• trochanteric bursa, ischial bursa, gluteofemoral bursa
