Calcific Tendinitis: What Is It Caused By and When Is It Cared For?

By Tom Nicholson

Calcific tendinitis is a condition that causes sharp pain a joint, when calcium deposits form around the tendons and then break free, triggering inflammation. It usually hits the rotator cuff and can affect either or both shoulders.

To date, no definitive cause for calcific tendinitis has been identified. Several possibilities have been eliminated from the list of possible causes. It's not triggered by too much calcium in the diet; people with the condition have normal calcium levels in their blood workup. Don't limit your calcium intake if you have calcific tendinitis because you could increase your risk of osteoporosis as your body makes up the lack by scavenging it from your bones.

There are some links between certain metabolic conditions, such as kidney disease, and calcific tendinitis, though whether the joint pain causes the kidney condition or vice versa is still being analyzed. While overuse of the shoulder joint can generate tendinitis, there is a difference between shoulder joint and rotator cuff wear and calcific tendinitis.

May be related to age

Some speculate that age, and the gradual ramping down of human growth hormone in the late 20s are one trigger for calcific Tendinitis, as it doesn't happen to people under the age of 30, there may be Tendinitis from overuse injuries, but they usually don't have calcium deposits.

Symptoms

Oftentimes, calcific tendinitis is asymptomatic, especially if the deposits themselves occur within the tendons deeply enough that they are not felt. In some cases, you may feel discomfort or pain if a large calcium deposit in your rotator cuff tendon causes so-called "shoulder impingement syndrome," where you get some pain when you raise your arm overhead.

In addition, calcium crystals may shed off of the deposits and cause the tendons to become acutely inflamed. Oftentimes, people aren't even aware they have calcific tendinitis until they experience this kind of attack. Surprisingly, though, this is also when the calcium deposits can be reabsorbed by the body.

Sudden onset

Calcific Tendinitis has a quick trigger point, rather than small amounts of pain that gradually worsen. Most cases, when it triggers, it's because the calcium crystals have broken free; the symptoms go away within a week or two as they're re-absorbed by the body.

If you visit your doctor during a bout of acute calcific Tendinitis, it can be seen on an X-ray. Most treatments are taking over the counter inflammation relievers and icing the shoulder or joint. Performing range of motion exercises to keep the shoulder limber is also recommended; it prevents the 'locked shoulder' syndrome, and helps you avoid losing muscle mass.

In the event of particularly severe pain, your doctor may give you a steroid or cortisone injection to relieve inflammation. For extreme cases, the deposits may be broken down with ultrasound or a hypodermic needle and extracted with a syringe. It's rare, but on some occasions, arthroscopic surgery may be necessary. - 30453
