What is Shoulder Instability?
Shoulder instability is a condition characterized by the abnormal movement of the shoulder joint, which can result in either a complete dislocation or a partial dislocation known as subluxation. This instability often arises from trauma, repetitive overhead activities, or inherent ligamentous laxity, leading to significant pain and functional limitations.
The most frequent type of shoulder dislocation is anterior dislocation, where the humeral head shifts forward out of the glenoid cavity. However, shoulder instability can also manifest as posterior dislocation or multidirectional instability, each requiring tailored treatment approaches to restore joint stability and function.
Causes and Symptoms
Risk is highest with an abducted and externally rotated arm (e.g., fall on outstretched hand). Symptoms can range from immediate noticeable dislocation to a sensation of slipping with or without pain, or “apprehension” with certain arm movements.
Immediate and Long-Term Care
Sudden dislocation requires immediate medical evaluation for nerve/blood vessel damage.
Pain relievers, muscle relaxants, and ice help manage discomfort.
For recurring instability, activity modification, physical therapy, or surgical stabilization may be considered.
Emergency room physicians can often manually reposition the joint.
Physical therapy typically starts 2-3 weeks post-dislocation for strengthening and stability.
