What to Consider With Cacific Tendinitis


By Tom Nicholson

A painful condition of the rotator cuffs and shoulders, calcific tendinitis is the result of calcium buildup under the shoulder blade in the tendons of the shoulder and around the rotator cuffs.

The exact cause is still uncertain. People with calcific tendinitis do not have elevated calcium levels in the blood, so it's unlikely to be a dietary overdose. As a result, people who have the condition are cautioned not to cut back on calcium intake, as this will merely cause their body to scavenge it from their bones, and run the risk of osteoporosis.

There may be metabolic triggers for calcified tendinitis, some doctors speculate that it may have a similar root cause as kidney or bladder stones, which are also defined by calcified lumps accumulating within the body. This is not a definitive connection, but a categorization of similar symptoms and an avenue of further investigation. Rotator cuff injuries do not make people more likely to develop calcified tendinitis.

Those above the age of 30 are generally seen to be at greater risk of developing calcific tendinitis, since the condition is rarely seen in those under the age of 30.

What are the symptoms of calcific tendinitis?

Calcified tendinitis is typically symptom free; the calcium nodule builds up under the rotator cuff, and it isn't until it sheds crystals that any pain occurs. If the calcium deposit grows deeply enough, it won't be felt as a lump or anything, though it may cause shoulder impingement syndrome if you raise your arm over your head.

Where the symptoms show up is when the calcium deposit sheds crystals and flakes of calcium, which act like very small knives in the tendons, or like burrs, and cause inflammation as the body tries to break them down and reabsorb them. Most times, the pain lasts for a week or two and the symptoms go away.

The onset of symptoms can be sudden, and the recommendation is that you stretch and maintain your full range of motion.

If the pain is very bad, it may be worth it to go to a general practitioner; an x-ray will show the calcium deposit clearly. In addition to aspirin, there's often recommendations to ice the shoulder, and to do range of motion exercises.

Severe pain can get your doctor to give you a shot of cortisone to reduce inflammation, or a steroid shot. Rarely, they may decide to run a hypodermic under the shoulder blade to break up the nodule and extract the pieces with a syringe. In a handful of cases, arthroscopic surgery to remove large deposits may be needed to restore the full range of motion to your shoulder.
