Calcifying tendinitis of the rotator cuff is a common disorder of the shoulder which affects mainly individuals between 30 and 50 years of age. The etiology is still a matter of speculation. The calcification is a reactive process actively mediated by cells in a viable environment. The deposit undergoes an evolution (precalcific stage - calcific stage with formative phase, resting period and resorption - postcalcific stage), which ultimately remodels normal tendon tissue. However, the evolutionary stages of the disease do not always follow the typical sequence. A symptomatic deposit may persist or postcalcific tendinitis develop. The treatment should be based on the knowledge of the natural history of the disease, which shows a strong tendency towards self-healing by spontaneous resorption of the deposit. The stage of evolution of the disease should be judged, combining pain history, morphology of the deposit on plain X-rays, and ultrasound findings. The therapeutic approach depends on the evolution of the disease. During the resorption phase we favor a conservative approach. For deposits which are not under resorption we propose a concept which consists of three steps: a conservative approach, extracorporal shock wave therapy (ESWT) or needling, and arthroscopic surgery. The efficacy of ESWT and needling has still to be proven. Patients with persisting pain after steps 1 and 2 are candidates for surgical removal of the deposit. We prefer the arthroscopic approach. In some cases an additional arthroscopic subacromial decompression (ASD) is indicated.
