Scapulothoracic Articulation

Bony landmarks

  • scapula
  • medial (vertebral) border
  • lateral (axillary) border
  • superior angle
  • lateral angle
  • inferior angle
  • spine of the scapula
  • root of spine of the scapula
  • coracoid process (GreekĄG korax = curve door handleĄF eidos = appearance)
  • not palpableĄG superior angle, glenoid cavity (GreekĄG glene = socket), supraglenoid tubercle, infraglenoid tubercle, supraspinous fossa, infraspinous fossa
    1. Have the subject sit in a high-back chair to relax scapular muscles.  Follow the outline of the scapula, you can find three borders (superior, lateral, and medial borders) and three angles (superior, lateral, and inferior angles).

    2. The spine of the scapula rests transversely across the upper portion of the scapula.

    3. By following the spine of the scapula medially, the root of the scapula is at the medial end of the spine of the scapula, which is a smooth triangular-shaped area.

    4. Just below the lateral end of the clavicle, the coracoid process can be identified as a round process.
