What are the signs and symptoms of MDI (Multidirectional Instability) or atraumatic shoulder instability?

MDI problems are generally related to recurrent episodes of dislocation.

Repeated subluxations often cause patients to be apprehensive about performing certain daily activities.
Vague symptoms are described, such as an indistinct pain in the shoulder. Patients may sense that something is not quite right with the shoulder during activities when the arm is in certain positions.
There may be pain caused by inflammation in the joint.
Patients may show signs of labrum and/or rotator cuff injuries that have resulted from the increased movement in the joint.
