Shoulder Injuries Commonly Caused by Workouts - Revere Health

Shoulders are a ball-and-socket joint similar to the hip, allowing the arms a greater range of motion. The shoulder socket’s shape (similar to a golf tee—flat on top), however, allows the ball of the upper arm bone to slip out of it easily, and this is why the shoulder gets dislocated more often than any other joint in the body.

Dislocations aren’t the only possible shoulder injury, though. Repetitive stress can cause injuries, particularly for people who play sports or engage in certain workouts. Here’s a look at some of the most common workout-related shoulder injuries.

Types of Injuries

 

In general, orthopedic surgeons group shoulder injuries into two categories:

  • Instability: Instability occurs when one of the shoulder joints moves or is forced out of its normal position. This can result in dislocation. Instability causes pain when raising the arm, and potentially a feeling as if the shoulder is slipping out of place.
  • Impingement: This is caused by excessive rubbing of the shoulder muscles against the top of the shoulder blade, known as the acromion. Impingement often occurs during exercises that require overhead arm motion and can lead to more serious injury.


Now, let’s look at three of the most common exercise-related shoulder injuries you may run into.

Rotator Cuff Injuries

 

The rotator cuff is a set of four muscles that sits around the ball of the shoulder joint, allowing for full range of motion. Rotator cuff injuries are a perfect example of impingement—they often take place during sports that involve lifting the hands over the head, including baseball (pitching), swimming (freestyle or butterfly strokes), tennis (serving) and weightlifting. These movements can cause the top part of the shoulder blade to pinch rotator cuff muscles.

In addition, repetitive motions can overload rotator cuff tendons, which cause them to swell and become inflamed—this is what’s called tendinitis. It can lead to a tear in the tendon that connects the rotator cuff muscles to the ball of the joint.

Symptoms of rotator cuff injuries may include:

  • Pain is the primary symptom, which gets worse when you raise your arm and, over time, may begin showing up even when you aren’t moving the arm
  • Clicking or popping sound when you move the arm
  • Limitation of movement
  • Loss of strength in the affected arm

AC Joint Injuries

 

Short for acromioclavicular joint, the AC joint is the location where the acromion meets the collarbone. In cases where ligaments connecting the acromion and collarbone are torn, this results in a separated shoulder. AC joint injuries can result from being hit hard in the shoulder, or by falling on an outstretched hand. Symptoms of an AC joint injury include:

  • Pain in the shoulder
  • In some cases, a bump on top of the shoulder where it’s been separated

 

Shoulder Dislocation

 

When the top of the upper arm bone, or the ball, slips out of its socket, shoulder dislocation occurs. The ball may slip forward, backward or downward. Many shoulder dislocation sufferers feel like the shoulder is starting to slip out of place, a feeling called instability. When the shoulder only slips partway out, this is called subluxation.

Shoulder dislocations can be caused by a strong hit to the shoulder, or by rotating the joint in the shoulder too far. Symptoms include:

  • A feeling when the shoulder pops out of place
  • Intense pain, directly following this pop
  • Swelling, bruising or weakness in the arm in some cases

 

If you feel any of these symptoms in your shoulder during a workout or sports activity, stop activity right away. Your doctor can advise proper treatment methods and future prevention techniques for these injuries.

I treat people of all ages in my practice—kids, athletes, adults and retirees––and enjoy being able to understand people’s unique situations in order to help them recover.
