difficult to abduct the arm to the horizontal level. Based on your anatomical
knowledge answer the following questions:
- What anatomical feature makes the shoulder joint particularly prone to dislocation
- Briefly describe the most stabilizing structure of the joint and why the head of the humerus is often displaced downwards
- In this case, what is the cause of subsequent flattening of the right shoulder and the difficulty in abducting the arm to a horizontal level.
- Briefly describe the ligaments and the muscles acting at the shoulder joint.
