The shoulder joint is one of the most mobile joints in the human body. This tremendous mobility can become disabling when a dislocation disrupts the normal stabilizers of the shoulder and leads to an unstable joint. During a dislocation, the ball and socket within the shoulder joint become separated. The shoulder can dislocate forward, backward or downward. Some individuals will have what is referred to as multidirectional instability (or MDI) which is often found in people that are “loose-jointed.” Dr. Jeff Padalecki, shoulder specialist serving Austin, Round Rock, and Cedar Park, Texas communities, is well trained in treating patients with this shoulder injury.
Athletes, in particular, are at risk for a shoulder dislocation when participating in competitive activities. In addition, athletes who compete in sports that involve overhead movements are especially at risk. Examples include basketball players, swimmers, pitchers, and tennis players. The repetitive, constant overhead motion can lead to wear and tear of the ligaments, muscles and other structures that normally secure the shoulder joint. This wear and tear leaves the joint susceptible to a dislocation.
Traumatic accidents are a common cause of shoulder dislocation. Acute dislocations are often caused by direct impact (such as in football) or other traumatic events (such as a car accident). Patients who have dislocated their shoulder in the past will often have weaker ligaments leading to chronic instability and ongoing dislocations. In young adults (35 and under) who sustain a traumatic dislocation, shoulder instability follows in the vast majority of cases. Individuals who are “double-jointed” or have connective tissue disorders may also be at greater risk for having loose ligaments which make them more susceptible to a dislocated shoulder.
What are the Symptoms of a Dislocated Shoulder?
The symptoms associated with a shoulder dislocation include:
- Muscle spasms
- Significant pain, which can be also felt along the arm
- Difficulty or inability to move the arm from its current position
- Numbness in the arm
- A “popping” sensation
- A visibly displaced shoulder
- Some discoloration or bruising
- Shoulder weakness
Prompt medical treatment should be sought for any suspected dislocation injury. Emergent care is focused on returning the shoulder to its normal position via a process known as reduction, whereby several methods are used to manually manipulate the dislocation and put the ball back into the socket. This procedure typically minimizes pain immediately when completed.
