Shockwave Therapy for Calcific Tendinitis of the Shoulder (Rotator Cuff)

Calcific tendinitis of the shoulder is a painful condition caused by calcium deposits forming within the rotator cuff tendons. It can lead to severe shoulder pain, stiffness, and significant limitation with daily activities such as lifting the arm, dressing, or sleeping on the affected side.

When pain persists despite rest, medication, or physiotherapy, shockwave therapy is a highly effective, non-invasive treatment option that can help break down calcium deposits and restore shoulder function.

What Is Calcific Tendinitis of the Shoulder?

Calcific tendinitis occurs when calcium hydroxyapatite crystals accumulate within the rotator cuff tendons, most commonly the supraspinatus tendon. The exact cause is not fully understood, but it is thought to be related to tendon degeneration and altered blood supply.

Common symptoms include:

• Sudden or progressive shoulder pain

• Pain with overhead or reaching movements

• Night pain and difficulty sleeping

• Reduced shoulder range of motion

• Sharp pain during lifting or rotation

Calcific tendinitis is different from general rotator cuff tendinopathy and often does not respond well to rest alone.

What Is Shockwave Therapy?

Shockwave therapy (Extracorporeal Shockwave Therapy – ESWT) uses high-energy acoustic waves to target injured tissue. In cases of calcific tendinitis, shockwave therapy is particularly effective because it can disrupt calcium deposits and stimulate the body’s natural healing process.

It is widely used in orthopaedics and sports medicine as an alternative to injections or surgery.

How Shockwave Therapy Helps Calcific Tendinitis

Shockwave therapy addresses both the calcium deposits and the associated tendon pain:

• Breaks down calcific deposits within the rotator cuff tendon

• Stimulates reabsorption of calcium by the body

• Increases blood flow and tendon healing

• Reduces pain and inflammation sensitivity

• Improves shoulder mobility and function

Clinical studies show shockwave therapy can significantly reduce pain and improve outcomes in patients with chronic calcific tendinitis.

Shockwave Therapy vs Other Treatments

Treatment	Effectiveness for Calcific Tendinitis
Rest & anti-inflammatories	Temporary relief
Cortisone injections	Short-term, recurrence common
Ultrasound-guided lavage	Effective but invasive
Surgery	Last resort
Shockwave therapy	Highly effective, non-invasive

👉 Shockwave therapy is often used before considering injections or surgery, making it a preferred conservative option.

What to Expect During Shockwave Therapy

• Treatment duration: 5–10 minutes per session

• No injections or anaesthesia required

• Mild to moderate discomfort during treatment

• Typically 3–6 sessions, spaced weekly

• No downtime — normal daily activities allowed

Improvement is usually gradual over 4–12 weeks as calcium deposits reduce and tendon healing improves.

Is Shockwave Therapy Suitable for You?

Shockwave therapy may be suitable if you:

• Have confirmed calcific tendinitis on X-ray or ultrasound

• Experience persistent shoulder pain for more than 6–8 weeks

• Have limited response to physiotherapy or medication

• Want to avoid injections or surgery

It may not be suitable if you have:

• Acute fractures

• Bleeding disorders

• Pregnancy (local contraindication)

A thorough physiotherapy assessment is essential before treatment.
