Calcific tendinitis of the shoulder, medically known as tendinitis calcificans, is a condition in which calcium deposits develop in the rotator cuff tendons that help stabilise the shoulder joint. This can cause pain, inflammation, and restricted shoulder movement.
Symptoms may be caused not only by the calcium deposits themselves, but also by irritation and inflammation of the surrounding tissues.
Shoulder pain may develop suddenly, for example following overexertion or an awkward movement, or it may develop gradually over several weeks.
As the pain becomes more severe, it may also occur at night, and patients may find it difficult or impossible to lie on the affected shoulder. In addition to pain, the shoulder’s range of motion may also become restricted.
Calcific tendinitis of the shoulder is generally treated conservatively at first, without surgery. Treatment options may include anti-inflammatory medication, corticosteroid injections, or shockwave therapy.
If conservative treatments do not provide sufficient or lasting relief, surgical treatment may become necessary. During an arthroscopic procedure, the calcium deposits are removed, and, if necessary, surrounding scar tissue and adhesions are released and the space available for the rotator cuff is increased.
