Shoulder instability occurs when the head of the upper arm bone is forced out of the shoulder socket. This typically happens as a result of a sudden injury, such as a fall or accident.
Once a shoulder has dislocated, it is vulnerable to repeat episodes. When the shoulder is loose and slips out of place repeatedly, it is called chronic shoulder instability.
After surgery, your shoulder may be immobilized temporarily with a sling.
When the sling is removed, you will begin exercises to rehabilitate the ligaments. These exercises will improve the range of motion in your shoulder and prevent scarring as the ligaments heal. Your physical therapist will gradually expand your rehabilitation plan by adding exercises to strengthen your shoulder.
