The Connection between Shoulder Instability and Shoulder Dislocations in Los Angeles Athletes
Shoulder injuries affect countless athletes each year and one of the most common injuries is a shoulder dislocation. Once a shoulder dislocation occurs from a traumatic event or overuse, it is vulnerable to repeat dislocations. As the joint becomes loose and continues to slip out of place, it is known as chronic shoulder instability. Dr. Mark Getelman, board certified shoulder surgeon, is available to diagnose and treat shoulder instability and a dislocated shoulder in athletes of all levels.
What is Shoulder Instability?
The shoulder joint is considered the most mobile joint in the human body. The joint allows a great range of motion so people can engage in everyday, work and sporting activities. Unfortunately, this wide range of motion places the shoulder at risk for shoulder instability.
Shoulder instability is classified as a shoulder joint that is too loose and the ball (humeral head) has the ability to move excessively on the shallow socket (glenoid). When the shoulder is able to slide completely out of socket because of loose ligaments that do not hold the ball and socket in place, a shoulder dislocation occurs.
What is a Shoulder Dislocation?
Shoulder dislocations are relatively common in active individuals. This shoulder condition typically occurs from blunt force trauma to the joint during sports or from overuse and repetitive overhead motions.
A shoulder dislocation is characterized by the displacement of the humeral head (ball) from its usual position against the shallow socket (glenoid). The soft tissues that surround the shoulder must become injured in order for a dislocation to occur. In many cases, the labrum becomes torn and allows the ball to move out of the socket more easily.
Once a shoulder becomes dislocated for the first time and the supportive ligaments are torn or stretched and damaged, recurrent shoulder dislocations occur resulting in chronic shoulder instability. With more extensive instability, the glenoid and humeral head bone is also damaged. Once bone injury occurs, the likelihood of future dislocations increases.
