Summary
Biopsy specimen from 18 patients suffering from calcifying tendinitis were stained with different histologic and histochemical techniques. The results of these examinations seem to indicate that we are not dealing with a dystrophic calcification, but with a cell-mediated calcification of a living tissue. The process resembles an incomplete endochondral ossification.
Zusammenfassung
Histologische und histochemische Untersuchungen der Supraspinatussehne von 18 Patienten mit calcifizierender Tendinitis. Der Verkalkungsprozeß wird eingeleitet durch eine Transformation der Tendinocyten in Chondrocyten begleitet von einer Anreicherung alkalischer Phosphatase. In einer zweiten Phase kommt es, unter Mitwirkung der Chondrocyten, zur granulären Verkalkung und gelegentlich auch zur Ossifikation vergleichbar der enchondralen Ossifikation. Für die Annahme einer dystrophischen Sehnenverkalkung ergeben sich keine Hinweise.
