Rotator Cuff Calcific Tendonitis Treatment
Calcific tendonitis is a condition in which calcium deposits form within the rotator cuff tendons of the shoulder — most commonly the supraspinatus tendon — causing inflammation, intense pain, and significant loss of range of motion that can be debilitating during acute flare-ups. The calcium deposits develop through a predictable biological process in which cells within the tendon undergo changes that lead to calcium accumulation over time. The condition most commonly affects adults between the ages of 30 and 60, occurs more frequently in women, and is more prevalent in patients with diabetes and thyroid disorders. While many cases of calcific tendonitis ultimately resolve on their own as the body reabsorbs the calcium deposits, the resorptive phase — when the deposits are actively being broken down — is often the most painful stage, and some patients develop chronic deposits that persist for months or years and require intervention.
Dr. Jonathan Glashow is a board-certified orthopedic surgeon and Clinical Associate Professor of Orthopedic Surgery at NYU Grossman School of Medicine, with a traveling shoulder fellowship under Dr. Charles Rockwood and Dr. Richard Hawkins and fellowship training in arthroscopic surgery at the Southern California Orthopedic Institute/UCLA. Calcific tendonitis requires accurate staging to determine the right treatment at the right time — because the calcium deposits go through distinct biological phases, and the treatment approach during the silent, pain-free formative phase is very different from the approach during the acutely painful resorptive phase or the chronic phase when deposits persist and fail to resolve. With over 30 years of experience, more than 15,000 procedures, and membership in the Arthroscopy Association of North America, Dr. Glashow offers the full spectrum of calcific tendonitis treatment — from ultrasound-guided needling to arthroscopic calcium removal and subacromial decompression — at his Upper East Side practice in New York City.
Stages of Calcific Tendonitis
Calcific tendonitis progresses through three predictable stages. Understanding which stage the patient is in is essential for selecting the right treatment approach.
Pre-Calcification Stage: The tendon undergoes cellular changes at the microscopic level that create the conditions for calcium deposition. There are no symptoms during this stage, and the process is typically not detectable on imaging.
Calcific Stage: Calcium is deposited within the tendon and forms visible deposits. This stage has two distinct phases:
- Formative Phase (Silent): The calcium deposits are chalk-like and well-defined. Patients are often asymptomatic during this phase — many calcific deposits are discovered incidentally on X-rays taken for other reasons.
- Resorptive Phase (Painful): The body’s immune system recognizes the calcium deposits and begins to break them down. The calcium transforms into a toothpaste-like consistency, and the resorptive process triggers intense inflammation within and around the tendon. This is typically the most painful phase — patients may experience sudden, severe shoulder pain that can be excruciating and may mimic a rotator cuff tear. The acute resorptive phase usually lasts one to four weeks.
Post-Calcification Stage: The calcium deposits are gradually reabsorbed and the tendon begins to remodel and heal. Pain resolves as the inflammatory process subsides, and the tendon progressively returns to a more normal appearance on imaging.
Symptoms of Calcific Tendonitis
- Sudden, severe shoulder pain — often described as the worst shoulder pain the patient has ever experienced
- Pain that may wake the patient from sleep or prevent sleeping on the affected side
- Significant loss of shoulder range of motion during acute episodes
- Pain with overhead reaching, lifting, and reaching behind the back
- Tenderness over the top or front of the shoulder
- Pain that may radiate down the upper arm
- Episodes of intense pain lasting days to weeks, sometimes alternating with pain-free periods
Treatment Options
The majority of calcific tendonitis cases are managed successfully without surgery, particularly when the calcium deposits are in the resorptive phase and the body is actively breaking them down.
Conservative Treatment: Anti-inflammatory medications, corticosteroid injections into the subacromial space, ice, and activity modification can provide significant relief during acute flare-ups. Physical therapy focused on gentle range-of-motion preservation and rotator cuff strengthening helps maintain shoulder function while the deposits are resolving.
Ultrasound-Guided Needling (Barbotage): For deposits that are causing persistent symptoms or are not resolving on their own, Dr. Glashow offers ultrasound-guided needling — a minimally invasive procedure in which a needle is inserted directly into the calcium deposit under real-time ultrasound visualization. The needle mechanically breaks apart the deposit and aspirates (removes) as much of the calcium material as possible. A corticosteroid injection is typically administered at the same time to reduce surrounding inflammation. This procedure is performed in the office and does not require general anesthesia.
Arthroscopic Calcium Removal and Subacromial Decompression: When conservative treatment and needling have not provided adequate relief — or when the calcium deposit is large, dense, and resistant to resorption — arthroscopic shoulder surgery may be recommended. Dr. Glashow uses small instruments inserted through keyhole incisions to locate and remove the calcium deposit under direct visualization, debride any inflamed or damaged tissue, and perform a subacromial decompression to increase the space available for the rotator cuff tendons. This procedure is performed on an outpatient basis at Midtown Surgery Center.

Frequently Asked Questions About Rotator Cuff Calcific Tendonitis
What causes calcium deposits to form in the rotator cuff?
The exact cause is not fully understood. Calcific tendonitis appears to result from a cellular process within the tendon in which normal tendon cells undergo a transformation that leads to calcium deposition — it is not related to dietary calcium intake or calcium levels in the blood. Risk factors include age (most common between 30 and 60), female sex, diabetes, thyroid disorders, and possibly repetitive shoulder use. The condition is distinct from the degenerative calcification that can occur in aging tendons — calcific tendonitis follows a predictable biological cycle with the potential for spontaneous resolution.
Is calcific tendonitis the same as a rotator cuff tear?
No — they are different conditions, though they can produce similar symptoms. Calcific tendonitis involves calcium deposits forming within an otherwise intact rotator cuff tendon. A rotator cuff tear involves the tendon itself tearing or detaching from the bone. However, the two conditions can coexist — chronic calcific deposits can weaken the tendon and contribute to tearing over time. Dr. Glashow uses X-rays to identify calcium deposits and MRI to evaluate the structural integrity of the rotator cuff tendons, ensuring both conditions are diagnosed and addressed when present.
Will the calcium deposits go away on their own?
In many cases, yes. The natural history of calcific tendonitis includes a resorptive phase in which the body’s immune system actively breaks down and reabsorbs the deposits. However, this process can take months to years, the resorptive phase itself is often intensely painful, and some deposits — particularly those in the formative phase — may persist indefinitely without intervention. Dr. Glashow evaluates each patient’s stage of disease, deposit characteristics on imaging, and symptom severity to determine whether watchful management, needling, or surgical removal is the most appropriate approach.
What is ultrasound-guided needling?
Ultrasound-guided needling — also called barbotage — is a minimally invasive procedure performed in the office in which Dr. Glashow uses real-time ultrasound imaging to guide a needle directly into the calcium deposit. The needle mechanically fragments the deposit and the calcium material is aspirated (suctioned out) through the needle. A corticosteroid injection is typically administered afterward to reduce inflammation. The procedure takes approximately 15 to 30 minutes, does not require general anesthesia, and most patients experience significant improvement within days to weeks.
How long does recovery take after arthroscopic calcium removal?
Most patients experience significant pain relief within the first few weeks after arthroscopic surgery, as the source of inflammation has been directly removed. A sling is worn for comfort for a few days to one week, and gentle range-of-motion exercises begin almost immediately. Most patients return to daily activities within one to two weeks and to full shoulder function within four to eight weeks, depending on the extent of the procedure and whether a subacromial decompression was performed simultaneously. Physical therapy helps restore full range of motion and rotator cuff strength.
Can calcific tendonitis come back after treatment?
Recurrence is uncommon after successful treatment. Once the calcium deposit has been removed — either through the body’s natural resorption, needling, or arthroscopic surgery — the tendon heals and remodels. However, new deposits can occasionally develop in the same or opposite shoulder, particularly in patients with underlying risk factors such as diabetes or thyroid disease. If symptoms recur, Dr. Glashow can re-evaluate with imaging to determine whether new deposits have formed and recommend the appropriate treatment.
