Treatment of Calcific Tendinitis with Minimally Invasive Surgery (Shoulder Arthroscopy)

Calcific tendinitis is a very painful condition caused by the buildup of calcium deposits in the muscle-tendon structures of the shoulder (especially the supraspinatus tendon). Over time, these calcium deposits create pressure within or around the tendon, leading to restricted movement and night pain. It is more commonly seen in active individuals between 30–60 years old and is more frequent in women.

Although the exact cause of calcific tendinitis is not fully known, factors such as microtraumas (minor injuries), poor blood supply, and biochemical changes are thought to play a role. Symptoms typically include a sudden onset of severe shoulder pain, difficulty lifting the arm overhead, weakness in the shoulder, and pain that wakes the person from sleep at night. The calcium buildup is easily detected using X-ray or MRI imaging.

In mild to moderate cases, the first-line treatment preference is painkillers or steroid injections. However, surgical intervention is required for cases that do not respond to these treatments, when the calcium deposit is large, or when the pain severely impacts the patient’s quality of life.

With minimally invasive surgery (arthroscopic debridement, a “keyhole” procedure), the calcium buildup can be directly visualized and removed. During the operation, the calcium deposits within the tendon are evacuated using special instruments, and any irritation to the surrounding tissues is resolved. If necessary, a tendon repair is also performed during the same session. This method provides maximum benefit with minimal tissue damage.

Thanks to the arthroscopic method, the recovery process is faster compared to open surgery, the scars are smaller, and the patient can return to daily life more comfortably. The success rate is high, and the vast majority of patients regain a painless, functional shoulder.
