Questions and Answers
  • 1. 
    MCL consists of:
    • A. 

      Anterior ligament, posterior ligament, oblique ligament.

    • B. 

      Anterior bundle, transverse ligament, posterior bundle.

    • C. 

      Transverse ligament, medial bundle, annular ligament (lateral portion).

  • 2. 
    The radius articulates with the Trochlea of the Humerus.
    • A. 

      True

    • B. 

      False

  • 3. 
    The radius is a major forearm bone contributing to the wrist joint. When the radius moves, the wrist moves with it.
    • A. 

      True

    • B. 

      False

  • 4. 
    Statement: The annular ligament of radius is attached to the anterior and posterior margins of the notch.The ligament is more “cup-shaped” than “ring-shaped”, therefore the head of the radius cannot slip upwards.
    • A. 

      True

    • B. 

      False

  • 5. 
    Which bundle tightens in extension? (MCL-complex)

      Anterior

    • B. 

      Posterior

    • C. 

      Transverse

  • 6. 
    The radial head is considered a second stabilizer in the elbow with an intact MCL complex.
    • A. 

      True

    • B. 

      False

  • 7. 
    In extension: resistance to valgus stress is shared equally by MCL, capsule and joint articulation
    • A. 

      True

    • B. 

      False

  • 8. 
    For resisting varus stress in extension, the main stabilizer is the LCL.
