Shoulder calcification is a common, often painful condition that can significantly disrupt daily life. It can be silent during the day and cause severe pain at night, so it shouldn’t be underestimated. The main problem, aside from the pain, is the gradual reduction in joint range of motion. While medical treatments can sometimes relieve symptoms, surgery may be necessary if this fails. What are the warning signs? What are the different treatments available before surgery? When should you consider surgery? And, most importantly, how is it performed? A comprehensive overview to better understand shoulder calcification.
Shoulder Calcification: What Are We Talking About?
A calcium deposit in the shoulder tendon
Shoulder calcification, also called calcific shoulder tendinopathy , is a condition characterized by the formation of a deposit of calcium crystals in one of the rotator cuff tendons—most commonly the supraspinatus . This deposit is not strictly speaking a “bone,” but an accumulation of calcium salts that infiltrate the tendon fibers, causing inflammation , pain , and sometimes compression of the surrounding structures . There are generally several phases in the evolution of calcification:
- A phase of deposit formation (often silent),
- A so-called resting phase , where calcification is stable but can begin to cause problems,
- A resorption phase , where the body tries to “digest” the calcification, which can cause very painful acute inflammation .
Who is affected? And why?
Shoulder calcification mainly affects women between the ages of 25 and 50 , but can also occur in other age groups or in men. It is independent of trauma , contrary to what one might think. The exact causes are still poorly understood, but several contributing factors have been suggested:
- Disorders of local vascularization of the tendon,
- Repeated microtraumas linked to certain professions or sporting activities,
- Hormonal imbalances ,
- Individual predispositions .
It is therefore not a “self-inflicted” disease, but rather a biological process that can occur spontaneously in healthy people.
Symptoms: When should you be concerned about shoulder calcification?
Sometimes very intense pain
The main symptom of shoulder calcification is pain . This can be moderate or severe , depending on the stage of calcification. It is often located on the front or outside of the shoulder , sometimes radiating to the arm, and exacerbated at night , which greatly disrupts sleep. During the spontaneous resorption phase (disappearance phase), we sometimes speak of an acute hyperalgic crisis : the pain then becomes sudden, very sharp, pulsating , making any movement difficult, often requiring major analgesic treatment with morphine. This is a common reason for going to the emergency room because the pain is so severe. This pain can occur without any obvious cause , or be triggered by a trivial movement.
Functional discomfort and loss of mobility
Besides pain, calcification can lead to a progressive loss of mobility , with:
- Difficulty raising or turning the arm,
- Loss of strength,
- Feeling of a “stuck” shoulder.
These limitations can become particularly disabling in everyday life: getting dressed, carrying a bag, driving, or simply grabbing an object from a cupboard can cause pain.
Treatments: from alternative medicine to surgery
The first options: rest, physiotherapy, injections
Before considering surgery, two specific medical procedures can be proposed to relieve pain and promote the resorption of calcification.
Subacromial infiltration
This technique involves injecting an anti-inflammatory (corticosteroid) into the bursa located just above the rotator cuff tendons, under a bony protrusion called the acromion . Performed in consultation or in interventional radiology, subacromial infiltration allows:
- Reduce local inflammation ,
- Reduce night pain ,
- Improve shoulder mobility in the short term.
It is a simple, quick and often well-tolerated procedure, which may be enough to relieve some patients, particularly during a painful crisis.
Puncture-crushing-infiltration of calcification under X-ray
When the calcification is clearly visible on X-rays and accessible, it is sometimes possible to perform a procedure called puncture-trituration-infiltration . It is performed in the radiology room, under X-ray guidance for greater precision. The procedure involves several steps:
- A puncture of the calcium deposit with a fine needle,
- Gentle trituration , that is to say a massage of the calcification with a needle to try to fragment it, to partially dissolve it by injecting physiological serum, and to aspirate it,
- A final infiltration of a corticosteroid to calm local inflammation.
This technique can effectively relieve pain and facilitate the natural resorption of the deposit, while avoiding surgery. It constitutes a relevant intermediate alternative between simple medical treatment and surgery.
When should surgery be considered?
When pain persists despite several months of well-conducted medical treatment, or when functional discomfort becomes significant, it may be advisable to remove the calcification surgically . Other criteria may justify the intervention:
- Bulky calcification,
- Hard shape and clearly visible on imaging,
- Professional or sporting context requiring rapid recovery.
In all cases, the decision for surgery is discussed on a case-by-case basis , after a precise clinical and radiological assessment (x-ray, ultrasound, MRI).
Surgery explained simply
Minimally invasive, arthroscopic surgery
The procedure is performed arthroscopically , a minimally invasive technique that allows access to the inside of the shoulder without opening it . The surgeon makes two to three small incisions of 5 to 10 mm around the joint, through which a mini-camera (arthroscope) and fine surgical instruments are inserted. The first step consists of performing a subacromial decompression : this involves slightly planing the acromion , a bony outgrowth located above the tendons, in order to eliminate the conflict between the bone and the tendon . This procedure, carried out with great precision, reduces pressure on the tendons and prevents friction that causes inflammation. Arthroscopy has several advantages over so-called “open” surgery:
- Almost invisible scars ,
- Respect for surrounding muscles and ligaments,
- Less post-operative pain ,
- Faster recovery of mobility,
- Reduced risk of infection .
Before removing the calcification, the surgeon takes care to check the integrity of the tendons , particularly that of the long biceps . This tendon, although not essential for the proper functioning of the shoulder, can be the source of pain when it is injured. If it is damaged, a tenotomy can be performed: the tendon is then cut cleanly to eliminate the pain without compromising the use of the arm. The excision of the calcification can then begin. Using a needle, the surgeon precisely locates the calcareous area within the tendon. This is often visible by transparency. A small incision is made in the axis of the tendon fibers, thus creating an exit path. Using a hook or a curette, the calcification is dislodged and extracted . It then spreads into the subacromial space, then is carefully suctioned to avoid any subsequent inflammatory reaction. At the end of the procedure, the joint is washed thoroughly , then the small incisions are closed. The whole process generally takes place in less than an hour, under general or local anesthesia, with a return home the same day .
Before the operation: surgical and anesthesiologist consultation
Before any intervention, a pre-operative surgical consultation is essential. It allows:
- Confirm the indication for surgery after analysis of imaging tests,
- Explain in detail the operating protocol , the expected benefits and any possible risks,
- Answer any questions or concerns the patient may have.
A preoperative assessment is carried out by the surgeon before the surgical procedure. The doctor will take care to examine all the tendons separately, then use X-rays and an MRI to check for tendon rupture, as well as to analyze the aggressiveness of the acromion on the rotator cuff. Then, a consultation with an anesthesiologist is organized, generally within 2 to 4 weeks before the procedure. Shoulder calcification operations are all performed under general anesthesia, and may even be combined with loco-regional anesthesia in order to minimize postoperative pain. These steps are important to calmly prepare for the procedure and ensure a personalized and reassuring journey. NB: It is imperative to stop smoking at least during the month preceding the operation. Nicotine absorption alters blood flow, which can lead to complications during and after the operation.
After surgery: recovery and results
After surgery, the shoulder needs time to heal in the best conditions. For the first 2 to 4 weeks , the arm is held in a compression sling , to be worn day and night . This sling helps limit movement and protect the tendons during the initial healing phase. When you are resting, sitting or in the shower , you can remove the sling briefly and let the arm rest alongside your body. However, it is strictly forbidden to actively raise your arm or spread it to the sides during this period. From the first few days, you will begin gentle self-rehabilitation with pendulum movements . These simple exercises, which consist of letting the arm swing gently under the effect of your body weight, help preserve the mobility of the joint without putting stress on the tendons. Dr. Levy will show you how to perform them correctly when you are discharged. The stitches are absorbable , which means they will fall off naturally after 15 to 20 days . Once the scars have closed, it is advisable to massage them regularly with a moisturizer to prevent adhesions from forming under the skin . Regular monitoring is provided by Dr. Levy, with scheduled post-operative consultations to assess the progress of recovery , adjust rehabilitation if necessary, and support you step by step until you fully resume your activities. Complete healing takes approximately 4 months , including 3 months of rehabilitation.
What patients often ask
Does calcification come back?
Recurrence of calcification in the same location is rare . Once surgically removed, the area is usually “cleaned,” and the deposits do not reform. However, it may happen that a new calcification appears on another tendon , especially if the initial contributing factors are not corrected, and especially on the contralateral shoulder. Regular monitoring and good joint hygiene can limit this risk as much as possible .
Is it a painful operation?
This is a legitimate question, and rest assured, the answer is no in the majority of cases. Thanks to current arthroscopy techniques, the procedure is minimally invasive , the tissues are preserved, and the pain is much less than that caused by the calcification itself. Post-operative care includes:
- Prolonged locoregional anesthesia is sometimes used for the first few hours after surgery,
- Suitable painkillers ,
- Progressive physiotherapy to avoid any stiffness.
In summary: the operation is well tolerated , and recovery is rapid in the vast majority of cases.
In conclusion
Shoulder calcification is a common but benign condition that can sometimes become extremely painful and disabling. While medical treatments are sufficient in many cases, surgery remains a simple, effective, and well-tolerated option when the situation requires it. Don’t hesitate to consult us if you have any questions: a precise and personalized assessment will allow you to quickly regain comfort and mobility.
