Complications of a dislocated shoulder may include:
- Tearing of the muscles, ligaments and tendons that reinforce your shoulder joint
- Nerve or blood vessel damage in or around your shoulder joint
- Susceptibility to re-injury (shoulder instability) if you have a severe dislocation or repeated dislocations
If ligaments or tendons in your shoulder have been stretched or torn, or if nerves or blood vessels surrounding your shoulder joint have been damaged, you may need surgery to repair these tissues.
