Basic anatomy

Perhaps you would like to understand better why your shoulder is causing
problems, where exactly the injury or damage lies and what any planned
operation would change and repair. To this end I would like to explain to you the most important anatomical structures of the shoulder joint, with the help of this diagram. The three-dimensional shoulder model will be used to explain the problem in further detail.


  1. Shoulder roof (acromion)
  2. Acromioclavicular joint (AC-joint)
  3. Bursa
  4. Long biceps tendon
  5. Supraspinatus (SSP) (above) and Infraspinatus (ISP) (behind)
  6. Subscapulaaris (SSC)
  7. Tuberculum majus = base of SSP and ISP
  8. Tuberculum minus = base of SSC
  9. Shoulder socket (glenoid)
  10. Base of biceps tendon (possible SLAP lesion)
  11. Base of capsular ligaments (possible Bankart lesion)

5 & 6 = Rotator cuff
