What is Shoulder Instability?

What Causes Shoulder Instability?

The shoulder has a wide range of motion because the socket is shallow and the capsule and muscles keep the joint centered. A traumatic dislocation can damage the front labrum and capsule. Repeated overhead activity, naturally loose ligaments or incomplete rehabilitation can also reduce stable control of the joint.

Symptoms

• A feeling that the shoulder will come out when the arm moves back and out
• A sudden slipping or dead-arm sensation during overhead sport
• Fear of movement and stiffness around the shoulder after a dislocation
• Recurrent insecurity after episodes of partial slipping

Frequently Asked Questions

Can shoulder instability improve with physiotherapy?

After a first episode without major bone loss, tailored exercises for shoulder-blade control and the rotator cuff can help. Recurrent dislocation, a labral tear or bone damage requires an orthopedic assessment to determine whether surgery should be considered.
