Shoulder Instability: Learn Why Your Shoulder Pops Out and Back In

You came here wondering why your shoulder pops out, and we have the answer for you. The short reason is, that things are just too loose!  In other words, the static stabilizers which include the joint capsule, ligaments, and labrum are overstretched, torn, or detached.  These structures ensure that the joint stays in place, however, the shoulder allows a large range of motion at the sacrifice of stability. How does a shoulder become instable?  Well, shoulder instability can either be atraumatic or traumatic.

For Instance, traumatic events include landing on your shoulder, falling on an outstretched hand, or reaching too far up and behind like serving a volleyball can absolutely cause your shoulder to pop out.

Significant trauma can cause dislocation or a subluxation. In other words, a dislocation occurs when the humerus completely falls out of the socket.  On the contrary, a subluxation occurs when the humerus quickly pops in out the socket. Atraumatic instability is caused by repetitive motions that stretch the structures. It’s also be caused by being genetically predisposed for laxity. Laxity can be a predisposition to spontaneous subluxation or dislocation.

Top Reasons Your Shoulder Pops Out

Commons symptoms of shoulder instability include the following:

• Clicking and Popping
• Pain with subluxation or dislocation
• Giving away
• Going or Popping in and out
• Loss of range of motion, swelling, and bruising can occur with dislocation

How Can Physical Therapy Help with Shoulder Instability and Popping?

First, it’s important to consider dynamic stabilization. The rotator cuff, a group of 5 muscles, are the primary dynamic stabilizers of the shoulder. Good shoulder stability heavily relies on postural awareness and muscular strength. Therefore, exercise and treat these muscles regularly to improve dynamic stabilization.
