Humerus Shoulder

Humerus and Shoulder
Show Answers:

  1. What is the most common fracture point of the humerus?
    Surgical neck.
  2. Lateromedial projection of the humerus.
  3. Lateromedial projection of the humerus?
    • Rotate humerus laterally
    • elbow joint 90 degrees
    • thumb down
    • CR: perpendicular to mid-shaft
    • 40'' SID
  4. AP humerus.
  5. How do you position for the AP projection of the humerus?
    • Anatomical position
    • 40'' SID
    • CR: perpendicular to mid-shaft
    • Suspend respiration
    • This projection can be performed upright or supine
  6. What are the routine images of the humerus?
    AP projection and mediolateral or lateromedial projection.
  7. Superior aspect of the humerus.
  8. Anatomy of the proximal humerus.
  9. What does the proximal end of the humerus consist of?
    Head, anatomic neck, greater and lesser tubercles, and surgical neck.
  10. What are the characteristics humerus?
    Largest and longest bone of the upper limb.
  11. Cross Table Transthoracic Lateral Position
  12. Transthoracic Lateral Position Lawrence Method
    • Raise unaffected arm overhead
    • Affected arm up against bucky
    • CR: axillary border at the level of the surgical neck
    • Use a breathing technique
  13. Y-View Position
    • Can be done AP (table) or PA (upright)
    • Medial border of scapula and head of humerus are perpendicular to the (IR)
    • CR: perpendicular to glenohumeral joint
  14. Inferosuperior Axial Projection.
    • Patient supine with shoulder built up approx 3” off table
    • Cassestte placed as close to patient’s neck as possible
    • Horizontal beam through the axilla
    • Greater the abduction ; greater the angle
  15. AP Projection External Rotation.
    • Rotate humerus externally, palm supinated
    • CR: parallel to coracoid process
    • Collimation
  16. AP Projection Internal Rotation.
    • AP Position
    • Rotate elbow internally with pronated hand
    • CR: parallel to the coracoid process 1'' below
    • Do not over rotate
    • Collimation
  17. What are the trama views of the shoulder?
    • AP Projection Neutral
    • Transthoracic Lateral Position also known as the Lawrence method
  18. What are the routine views of the Shoulder?
    • AP Projection Internal Rotation
    • AP Projection external Rotation
    • Y-View Position
    • Inferosuperior Axial Projection
  19. Clavical anatomy.
  20. Lateral of the shoulder joint.
  21. PA of the shoulder.
  22. AP of the shoulder joint.
  23. What are the two bones that make up the shoulder?
    The scapula and clavicle.
