摘要
旋轉環帶(rotator cuff)之鈣化性肌腱炎(calcifying tendonitis)為一不明原因之疾病，其特徵為細胞媒介(cell-mediated)之鈣質沉積，沉積物會隨著時間自然吸收，而後肌腱逐漸痊癒。鈣質沉積之過程中，病人可完全不痛，或僅輕微至中等度不適，但當鈣質被吸收之時，會出現急性疼痛。充分瞭解鈣化性肌腱炎之病理與臨床症狀，並配合適當之X光檢查，方能正確診斷，並正確治療。吾等報告四位鈣化性肌腱炎病例，所有病患皆肩部急性嚴重疼痛與動作限制。X光檢查可確立診斷，並定位鈣質沉積之位置。所有病患於類固醇與麻藥之局部浸潤後，皆立即減輕症狀；復經其他保守療法，包括口服止痛藥物與物理治療，而於數日內痊癒。

Calcifying tendinitis is characterized by cell-mediated calcium deposition in nondegenerative rotator cuff tendons. The deposits normally undergo spontaneous resorption followed by subsequent healing of the tendon. During the deposition of calcium, the patient may be either free of pain or suffer only a mild to moderate degree of discomfort; however, the disease becomes acutely painful when the calcium is being resorbed. Successful treatment strategies can be formulated based on the clinical and radiographic features, and an understanding of the pathology involved. Four patients with calcifying tendinitis of the rotator cuff are presented. All had an acute onset of severe shoulder pain and limitation of movement. A plain radiograph identified and localized the calcific deposit on individual tendons. Infiltration of triamcinolone and local anaesthetic into the calcified area itself brought dramatic improvement. Within a few days of conservative treatment, all patients had a substantial reduction in discomfort.
