Key points about shoulder subluxation
- Shoulder subluxation is a partial dislocation where the upper arm bone slips partially out of the socket.
- It’s usually caused by trauma, overuse or underlying joint instability.
- Symptoms include pain, shoulder instability and reduced movement.
- Treatment usually includes rest, physical therapy and, in some cases, surgery.
- Early intervention can prevent recurring instability and long-term damage.
