Shoulder osteoarthritis-Anatomy

Your shoulder is made up of three bones:

 

  • Upper arm bone (humerus)
  • Shoulder blade (scapula)
  • Collarbone (clavicle)

The head of your upper arm bone fits into a rounded socket in your shoulder blade. This socket is called the glenoid. A combination of muscles and tendons keeps your arm bone centered in your shoulder socket. These tissues are called the rotator cuff.
