Shoulder instability is usually caused from a fall on an outstretched arm or being hit in the arm while the arm is out to the side.
Many times this will damage the shoulder labrum (the soft tissue ring that helps the shoulder stay in place) or it may even damage the bone making the shoulder more unstable. Milwaukee Brewers relief pitcher, Jim Henderson, recently underwent arthroscopic shoulder surgery. The expected rehab time is four months, so Henderson should be ready for spring training if he doesn't have any setbacks.
Treatment usually starts with physical therapy to restore the shoulder stability and range of motion, decrease pain, and increase shoulder muscle strength and coordination. If instability persists we may do surgery to repair the stabilizing structures in the shoulder joint.
