What Is Rotator Cuff Calcific Tendinopathy?

Rotator cuff calcific tendinopathy is a shoulder condition where calcium forms inside one of the rotator cuff tendons. You may also hear it called calcific tendonitis.

A calcium deposit does not always cause the same level of pain. At times, symptoms may settle. At other times, the shoulder can become very painful as the deposit becomes irritated or starts to break down.

The symptoms can resemble rotator cuff tendinopathy. Assessment helps determine how your pain, movement and strength fit together rather than relying on a scan alone.

What Does Calcific Tendinopathy Feel Like?

The symptoms vary. Some people notice a gradual increase in shoulder pain. Others experience a much faster and more painful flare.

You may also notice weakness with pushing, lifting or reaching. Gym exercises, swimming, throwing and overhead work can become uncomfortable when the shoulder is irritable.

Can Calcific Tendinopathy Go Away?

Yes. Many cases settle without surgery. The calcium deposit may reduce as the body gradually breaks it down.

However, symptoms do not always follow a smooth path. A painful flare may temporarily reduce your shoulder movement and make normal activities difficult. Protecting comfortable movement during this stage can help reduce unnecessary stiffness.

As pain settles, rehabilitation can progressively rebuild shoulder strength and tolerance for work, gym, sport and everyday tasks.

Why Does Calcium Form in a Rotator Cuff Tendon?

The exact cause remains unclear. Changes within the tendon can allow calcium crystals to form, but the process varies between people.

Activity can influence symptoms even when it did not cause the deposit. A sudden increase in overhead work, gym pressing, throwing, lifting or other shoulder load may aggravate an already sensitive tendon.

How Is Calcific Tendinopathy Diagnosed?

A physiotherapy assessment can examine your shoulder movement, strength, pain pattern and the tasks that reproduce your symptoms. Your physiotherapist may also assess shoulder blade control and consider other possible sources of shoulder pain.

An X-ray can show a calcium deposit. Ultrasound may also identify the deposit and provide information about the rotator cuff tendon and nearby bursa.

Imaging findings need to be considered alongside your symptoms and examination. The aim is to understand what currently limits your shoulder and choose an appropriate management plan.

Should You Keep Exercising?

Usually, you can continue some exercise, but the amount may need to change during a painful flare.

The correct starting point differs between people. Pain level, movement, strength and your usual activities all influence exercise selection and progression.

When Might Other Treatment Be Considered?

If pain remains significant despite appropriate non-surgical care, your treating team may discuss additional options. These can include shockwave therapy, image-guided lavage or an injection.

The most suitable option depends on your symptoms, examination, imaging findings, previous treatment and individual goals. Your GP, sports doctor or other treating medical practitioner can help determine whether an additional procedure is appropriate.

Rehabilitation remains important when another treatment is used. Restoring movement, strength and load tolerance helps prepare the shoulder for everyday activity, work and sport.

How Can Physiotherapy Help?

Physiotherapy aims to match movement and loading to the stage of your symptoms. This can help you stay active without repeatedly doing too much too soon or allowing the shoulder to become unnecessarily stiff.

• Pain and activity management: modify sleep, lifting, work, gym and sporting loads during a flare.
• Movement: restore comfortable shoulder range as pain allows.
• Strength: progressively load the rotator cuff and shoulder blade muscles.
• Function: rebuild the tasks required for work, home, gym or sport.
• Progression: adjust exercises as your pain, movement and strength change.

When Should You Have Your Shoulder Assessed?

Consider an assessment when shoulder pain affects sleep, reaching, lifting, work, gym or sport. An assessment may also help when symptoms keep returning or you are unsure how much exercise is appropriate.

Seek assessment sooner if the pain is severe, your shoulder movement drops quickly or symptoms are not beginning to settle over the following one to two weeks.

If you already have an X-ray, ultrasound or MRI report, bring it to your appointment. Your clinician can consider the imaging alongside your symptoms, movement, strength and goals.

What to Do Next

If shoulder pain is limiting sleep, movement, lifting, work, gym or sport, a physiotherapy assessment can help identify your current pain stage and plan an appropriate progression.

Bring any relevant X-ray, ultrasound or MRI results with you. Your physiotherapist can consider them alongside your shoulder movement, strength, symptoms and goals.
