Calcifying tendinitis of the rotator cuff is a common disorder; its underlying mechanism still remains unknown. Although details of the clinical presentation(s) and pathological changes which are associated with calcific tendinitis are available, conservative management of this condition remains a topic of debate. About 90% of the patients can be treated non - operatively, but as some are resistant to conservative treatment; newer techniques or surgery should be indicated. Rheumatologists and radiologists have often described this shoulder abnormality, leading to its progressive differentiation from other painful shoulder syndromes. The conservative treatment includes the use of non - steroidal anti - inflammatory agents, roentegen therapy, physical modalities for controlling the pain and for preventing loss of joint mobility, local steroid injections, and open or arthroscopic surgeries. Results of non - operative treatments have also been satisfactory. These include heat, cold, range of motion and pendulum exercises, diathermy, short - wave, and radiation therapy. Rest, immobilization with a sling, and oral non - steroidal and steroid anti - inflammatory medications have also been mentioned. This review aimed at looking at calcific tendinitis of the rotator cuff with a wide vision in the light of modern advances; while at the same time, not disregarding the past experiences.
