Calcific tendinitis of the shoulder.

Calcific tendinitis of the shoulder is a process involving calcium deposition commonly in the rotator cuff tendons. It is a cell-mediated process that is often chronic in nature, but it is usually self-limiting with regard to its acute pain states. Nonoperative management is still the treatment of choice and is successful in up to 90% of patients. When conservative measures fail, a needling technique or surgical removal may be indicated; the trend is toward arthroscopic management. Acromioplasty should not be performed without radiographic signs of impingement. If a resulting large rotator cuff defect is found after removal of the calcific deposit, it may be worthwhile to close the defect arthroscopically with suture to prevent cuff tear progression and to promote healing.
