Tendinopathy vôi hoá, hoặc viêm gân biển bị hóa vôi, IS một căn bệnh đặc trưng bởi vôi hóa đa ổ trung gian tế bào, các mô sống. Sau khi biến mất tự phát của tiền gửi vôi hoá hoặc, ít thường, phẫu thuật cắt bỏ, dây chằng ngoại quan cho chính nó. Chú ý đến biểu hiện lâm sàng và X quang | Calcific Tendinopathy of the Rotator Cuff Pathogenesis Diagnosis and Management Hans K. Uhthoff MD FRCSC and Joachim W. Loehr MD FRCSC Abstract Calcific tendinopathy or calcifying tendinitis is a disease characterized by multifocal cell-mediated calcification of living tissue. After spontaneous disappearance of the calcific deposits or less frequently surgical removal the tendon reconstitutes itself. Attention to the clinical presentation and the radiologic morphologic and gross characteristics of the calcium deposit will facilitate differentiation between the formative phase and the resorptive phase which is of paramount importance in the management of this disease. Should conservative treatment fail surgical removal may be indicated during the formative phase but only under exceptional circumstances during the resorptive phase. Aspiration and lavage of the deposit should be performed only during the latter phase. J Am Acad Orthop Surg 1997 5 183-191 Calcific tendinopathy or calcifying tendinitis of the rotator cuff is a common disorder of unknown etiology in which multifocal cell-mediated calcification of a living tendon is usually followed by spontaneous phagocytic After resorption or surgical removal of the deposit the tendon reconstitutes itself. During the deposition of calcium the patient may be free of pain or may suffer only a mild to moderate degree of discomfort. The disease becomes acutely painful only when the calcium undergoes resorption. Calcifying tendinitis must be distinguished from degenerative or dystrophic calcifications which occur at the insertion into bone but not in the midsubstance of the tendon. Radiologic signs of degenerative processes are extremely rare in calcific tendinop-athies. Pathogenesis The etiology of calcifying tendinitis is still a matter of controversy. Circumscribed tissue hypoxia and localized pressure have been invoked as causative factors. Two fundamentally different processes leading to formation of .
